Scaling up of enzyme production requires optimization of the fermentation process. Most enzymes are produced under aerobic conditions, and as a result, require constant oxygen input, impacting fermenter design. Due to variations in the distribution of dissolved oxygen, as well as temperature, pH, and nutrients, the transport phenomena associated with these parameters must be considered. The highest possible productivity of the fermenter is achieved at maximum transport capacity of the fermenter.

Fermentation lock on homebrewing fermentation vessel A fermentation lock or airlock is a device used in beer brewing and wine making that allows carbon dioxide released during fermentation to escape the fermenter, while not allowing air to enter the fermenter, thus avoiding oxidation. There are two main designs for the fermentation lock. These designs work when half filled with water. When the pressure of the gas inside the fermentation vessel exceeds the prevailing atmospheric pressure the gas will push its way through the water as individual bubbles into the outside air.

On December 1, 2006, the water became contaminated after a slurry accident. A fist-sized crack in the fermenter of the Biogas Plant in Borgentreich-Natzungen brought large quantities of fermentation substrate into the Eselsbach and thus into the Bever, causing a massive fish die out. Trout, eels, grayling, crayfish, and other aquatic animals died, which also affected the adjacent fishpond sites.

The vat is kept at a constant temperature, also optimized for growth; the fungus can double its mass every five hours. When the desired amount of mycoprotein has been created, the growth medium is drawn off from a tap at the bottom of the fermenter. The mycoprotein is separated and purified. It is a pale yellow solid with a faint taste of mushrooms.

It is composed mainly of heavy fats, coagulated proteins, and (when in fermenter) inactive yeast.Charles W Bamforth, Beer: Tap Into the Art and Science of Brewing, 2nd ed. (Oxford University Press, 2003), p. 56. The term has its origins in the German word trübe (also trüb), which means cloudy, via the brewing and winemaking terms Trubstoff (cloudy + material) and Weintrub (wine + cloudy).

1:P. pastoris is able to grow on simple, inexpensive medium, with high growth rate. P. pastoris can grow in either shake flasks or a fermenter, which makes it suitable for both small- and large-scale production. 2:P. pastoris has two alcohol oxidase genes, Aox1 and Aox2, which include strongly inducible promoters. These two genes allow Pichia to use methanol as a carbon and energy source.

Since the typical fecal specimen is not sterile, the use of selective plates is mandatory. XLD agar, DCA agar, or Hektoen enteric agar are inoculated; all give colorless colonies as the organism is not a lactose fermenter. Inoculation of a TSI slant shows an alkaline slant and acidic, but with no gas, or production. Following incubation on SIM, the culture appears nonmotile with no production.

In 1989, after a trial on the balcony a fermenter of 20 cubic meters was developed. He founded in 1991, funded by the Canton of Zurich, the company Kompogas, which produces biogas and compost from vegetable waste. Schmid first had to prevail against numerous politicians to get green waste. As early as 2005, the Handelszeitung wrote that rising energy prices would help in the future for such projects.

Brewers of more common beer styles would ensure that no such bacteria are allowed to enter the fermenter. Other sour styles of beer include Berliner weisse, Flanders red and American wild ale.Lambic (Classic Beer Style) – Jean Guinard In winemaking, a bacterial process, natural or controlled, is often used to convert the naturally present malic acid to lactic acid, to reduce the sharpness and for other flavor-related reasons.

The discovery of penicillin ushered in a new age of antibiotics derived from microorganisms. Penicillin is an antibiotic isolated from growing Penicillium mold in a fermenter. The mold is grown in a liquid culture containing sugar and other nutrients including a source of nitrogen. As the mold grows, it uses up the sugar and starts to make penicillin only after using up most of the nutrients for growth.

Particularly exothermic fermentations may require the use of external heat exchangers. Nutrients may be continuously added to the fermenter, as in a fed-batch system, or may be charged into the reactor at the beginning of fermentation. The pH of the medium is measured and adjusted with small amounts of acid or base, depending upon the fermentation. For aerobic (and some anaerobic) fermentations, reactant gases (especially oxygen) must be added to the fermentation.

Fluidized Bed Gasifier in Güssing Burgenland Austria The gasification process does not rely on chemical decomposition of the cellulose chain (cellulolysis). Instead of breaking the cellulose into sugar molecules, the carbon in the raw material is converted into synthesis gas, using what amounts to partial combustion. The carbon monoxide, carbon dioxide and hydrogen may then be fed into a special kind of fermenter. Instead of sugar fermentation with yeast, this process uses Clostridium ljungdahlii bacteria.

Biological methanation can take place as an in-situ process within a fermenter (see fig. 3.1) or as an ex-situ process in a separate reactor (see fig. 3.2 to 3.4). Biological methanation in a biogas or clarification plant with a gas processing system (in-situ process) Hydrogen is added directly to the fermentation material during a fermentation process and the biological methanation takes place subsequently in the thoroughly gassed fermentation material.

The lush, workable fur was made into a number of products, most notably hats. Demand for furs for hats drove beavers nearly to the point of extinction, and the North American species was saved principally by a sudden change in style. The beaver possesses continuously (or endlessly) growing incisors, and is a hindgut fermenter whose cecum, populated by symbiotic bacteria, helps to digest plant-based material. These traits are not unique to beavers, and are in fact present among all rodents.

Flying Bison Brewing Company is a brewery in Buffalo, New York, USA. The brewery incorporated in 1995, opened for business in 2000, was started by two majority partners, Phil Internicola and Tim Herzog, along with 25 individual investors. The brewery began operations as a 20-barrel facility. In early 2004, it installed a full bottling line and upgraded its production capacity by adding a 40 barrel fermenter. The brewery has since expanded by more than 200% adding 4 more 40 barrel fermenters.

K. aerogenes is an outstanding hydrogen producer. It is an anaerobic facultative and mesophilic bacterium that is able to consume different sugars and in contrast to cultivation of strict anaerobes, no special operation is required to remove all oxygen from the fermenter. K. aerogenes has a short doubling time and high hydrogen productivity and evolution rate. Furthermore, hydrogen production by this bacterium is not inhibited at high hydrogen partial pressures; however, its yield is lower compared to strict anaerobes like Clostridia.

Klebsiella pneumoniae is a Gram-negative, non-motile, encapsulated, lactose- fermenting, facultative anaerobic, rod-shaped bacterium. It appears as a mucoid lactose fermenter on MacConkey agar. Although found in the normal flora of the mouth, skin, and intestines, it can cause destructive changes to human and animal lungs if aspirated, specifically to the alveoli resulting in bloody, brownish or yellow colored jelly like sputum. In the clinical setting, it is the most significant member of the genus Klebsiella of the Enterobacteriaceae.

Traditionally, the most common sahti brewing process is using a long step infusion mash that may last up to six hours, after which the wort is lautered through the kuurna. Unlike most beers, traditional sahti wort goes straight from the lauter tun to the fermenter without boiling. This increases the chances of infection by lactic bacteria somewhat, and the very low usage of hops also tends to make it keep poorly. However, this is only one of several brewing processes that have traditionally been used.

Hammermills grind the mix of corn, rye and barley malt to break it down for easier cooking. The mix is then moved into a large mash cooker where water and set back are added. The "set back" is a portion of the old mash from the previous distillation—the key step of the sour mash process, ensuring consistency from batch to batch. From the cooker, the mash heads to the fermenter where it is cooled to 60–70 °F and yeast is added again.

Sorbitol MacConkey agar is a variant of traditional MacConkey agar used in the detection of E. coli O157:H7. Traditionally, MacConkey agar has been used to distinguish those bacteria that ferment lactose from those that do not. This is important because gut bacteria, such as Escherichia coli, can typically ferment lactose, while important gut pathogens, such as Salmonella enterica and most shigellas are unable to ferment lactose. Shigella sonnei can ferment lactose, but only after prolonged incubation, so it is referred to as a late- lactose fermenter.

Benkei was born in 1923 into a poor day labourer family. After finishing four elementary classes, he worked as a manual worker (engine fitter assistant, then tobacco fermenter) in Nyíregyháza. From August 1944, he served in the Royal Hungarian Army during the Second World War and was captured on the Eastern Front and deported to the Soviet Union as a prisoner of war in January 1945. He returned to Hungary in July 1948, and soon he involved in the tobacco fermenting trade union. He joined Hungarian Working People's Party (MDP), the ruling Communist party in 1950.

Flagellates are a feature of all termite families except Termitidae, the so-called "higher termites". They are found exclusively in the hindgut, especially the paunch, an enlarged section of the hindgut with an anaerobic interior that serves as a fermenter. In R. flavipes, wood eaten by the termite is first broken up with the mandibles, treated with host endoglucanases from the salivary glands, ground up into small particles in the gizzard, and then treated with additional host cellulases in the midgut, freeing glucose for immediate absorption. It then passes into the paunch, where flagellates take up the partly-digested wood particles through endocytosis.

Arthur Dehon Little is credited with the approach chemical engineers to this day take: process-oriented rather than product- oriented analysis and design. The concept of unit operations was developed to emphasize the underlying similarity among seemingly different chemical productions. For example, the principles are the same whether one is concerned about separating alcohol from water in a fermenter, or separating gasoline from diesel in a refinery, as long as the basis of separation is generation of a vapor of a different composition from the liquid. Therefore, such separation processes can be studied together as a unit operation, in this case called distillation.

On May 8, 1944 the Army Special Projects Division (SPD) directed the Vigo Plant to convert its facilities for full-scale biological agent production. The plant was converted for biological warfare (BW) use by the H.K. Ferguson Construction Company; they added fermenter tanks, slurry heaters, laboratories and the other necessities of a biological warfare facility. The plant was to be the first U.S. anthrax factory and would be utilized filling a British order for anthrax bombs. In March 1944 the British had placed an order for 500,000 of these bombs which Winston Churchill, remarked, should only be considered a "first installment".
|
|
When it was conceived, the initial plan was for the Vigo Plant to be a production facility for anthrax and botulinum toxin. The 1944 order converting the plant to a BW facility directed that it become a factory capable of producing 275,000 boutlin bombs or one million anthrax bombs per month. The core of the Vigo Plant's BW operation was the anthrax fermenters installed during the renovations in 1944. There were 12 20,000 gallon fermenter tanks at Vigo, the total of 240,000 gallons which made it the largest bacterial mass-production line anywhere in the world at the time.

In some breweries, the hopped wort may pass through a hopback, which is a small vat filled with hops, to add aromatic hop flavouring and to act as a filter; but usually the hopped wort is simply cooled for the fermenter, where the yeast is added. During fermentation, the wort becomes beer in a process which requires a week to months depending on the type of yeast and strength of the beer. In addition to producing ethanol, fine particulate matter suspended in the wort settles during fermentation. Once fermentation is complete, the yeast also settles, leaving the beer clear.

If it is not removed, then the digesters can be blocked and will not function efficiently. This contamination issue does not occur with dry digestion or solid-state anaerobic digestion (SSAD) plants, since SSAD handles dry, stackable biomass with a high percentage of solids (40-60%) in gas-tight chambers called fermenter boxes.A Technological Overview of Biogas Production from Biowaste, Science Direct It is with this understanding that mechanical biological treatment plants are designed. The higher the level of pretreatment a feedstock requires, the more processing machinery will be required, and, hence, the project will have higher capital costs.

Like its perissodactyl relatives, the horses, tapirs, and other rhinoceroses, Paraceratherium would have been a hindgut fermenter; it would extract relatively little nutrition from its food and would have to eat large volumes to survive. Like other large herbivores, Paraceratherium would have had a large digestive tract. Granger and Gregory argued that the large incisors were used for defence or for loosening shrubs by moving the neck downwards, thereby acting as picks and levers. Tapirs use their proboscis to wrap around branches while stripping off bark with the front teeth; this ability would have been helpful to Paraceratherium.

The process of storing, or conditioning, or maturing, or aging a beer at a low temperature for a long period is called "lagering", and while it is associated with lagers, the process may also be done with ales, with the same result – that of cleaning up various chemicals, acids and compounds. ;Secondary fermentation During secondary fermentation, most of the remaining yeast will settle to the bottom of the second fermenter, yielding a less hazy product. ;Bottle fermentation Some beers undergo an additional fermentation in the bottle giving natural carbonation. This may be a second and/or third fermentation.

This use began with a renewed interest in Belgian style ales and later formed new styles altogether (Brewers Association, 2007 Great American Beer Festival Style Guidelines, section 13a, 16). Some breweries use 100% Brettanomyces for the fermentation of some of their beers, and omit Saccharomyces from the recipe. Some American brewers that use Brettanomyces may also include lactic acid producing bacteria such as Lactobacillus and Pediococcus in order to provide sourness to the beer. While Brett is sometimes pitched into the fermenter, aging in wood barrels previously inoculated with Brettanomyces is another method used to impart the complexity contributed by these strains of yeast.

A sanitizing solution, sulphur dioxideExplanation of the effects of sulfur dioxide (in German) or alcohol is sometimes placed in the fermentation lock to prevent contamination of the beverage in case the water is inadvertently drawn into the fermenter. This device may take the form of a tube connected to the headspace of the fermenting vessel into a tub of sanitized liquid or a simpler device mounted directly on top of the fermentation vessel. Currently, a popular fermentation lock that mounts on top of the fermentation vessel is the three-piece fermentation lock. Other models contain three bulbous chambers allowing for a broader range of pressure equalization.

A bacterium that is a non-lactose fermenter and ferments glucose, initially causes a yellow slant/yellow bottom (acid/acid reaction) after 8 hours but then converts to a red slant/yellow bottom after 24 hours (alkali/acid reaction). Whereas if it ferments both lactose and glucose, it results in a yellow/yellow tube and remains that way due to the large amount of acid produced in the reaction. Blackening of the bottom due to H2S production may mask the acid reaction (yellow) in the bottom of the tube. Salmonella enterica serovar Typhi may result in blackening of the medium at the interface of bottom and the slant.

Conditioning tanks at Anchor Brewing Company After an initial or primary fermentation, beer is conditioned, matured or aged, in one of several ways, which can take from 2 to 4 weeks, several months, or several years, depending on the brewer's intention for the beer. The beer is usually transferred into a second container, so that it is no longer exposed to the dead yeast and other debris (also known as "trub") that have settled to the bottom of the primary fermenter. This prevents the formation of unwanted flavours and harmful compounds such as acetaldehyde. ;Kräusening Kräusening is a conditioning method in which fermenting wort is added to the finished beer.

Hindgut fermenters generally have a cecum and large intestine that are much larger and more complex than those of a foregut or midgut fermenter. Research on small cecum fermenters such as flying squirrels, rabbits and lemurs has revealed these mammals to have a GI tract about 10-13 times the length of their body. This is due to the high intake of fiber and other hard to digest compounds that are characteristic to the diet of monogastric herbivores. Unlike in foregut fermenters, the cecum is located after the stomach and small intestine in monogastric animals, which limits the amount of further digestion or absorption that can occur after the food is fermented.

Since 1998, the United States Department of Agriculture, Agricultural Research Service (ARS) has experimented with using the fungus Myrothecium verrucaria as a biologically based herbicide against kudzu. A diacetylverrucarol spray based on M. verrucaria works under a variety of conditions (including the absence of dew), causes minimal injury to many of the other woody plants in kudzu-infested habitats, and takes effect quickly enough that kudzu treated with it in the morning starts showing evidence of damage by midafternoon. Initial formulations of the herbicide produced toxic levels of other trichothecenes as byproducts, though the ARS discovered growing M. verrucaria in a fermenter on a liquid diet (instead of a solid) limited or eliminated the problem.

A home-brewing setup showing accumulated trub, or lees, at the bottom of the carboy In the process of brewing beer, trub is the term used for the material, along with hop debris, left in the whirlpool or hopback after the wort has been boiled then transferred and cooled. Brewers generally prefer that the bulk of the trub be left in the whirlpool rather than stay in contact with the fermenting wort. Although it contains yeast nutrients, its presence can impart off-flavors in the finished beer>. Trub may also refer to the lees, or layer of sediment, left at the bottom of the fermenter after the yeast has completed the bulk of the fermentation.

While foregut fermentation is generally considered more efficient, and monogastric animals cannot digest cellulose as efficiently as ruminants, hindgut fermentation allows animals to consume small amounts of low-quality forage all day long and thus survive in conditions where ruminants might not be able to obtain nutrition adequate for their needs. Hindgut fermenters are able to extract more nutrition out of small quantities of feed. The large hind-gut fermenters are bulk feeders: they ingest large quantities of low- nutrient food, which they process more rapidly than would be possible for a similarly sized foregut fermenter. The main food in that category is grass, and grassland grazers move over long distances to take advantage of the growth phases of grass in different regions.

Quorn (it derives its name from the Leicestershire village of Quorn)Oxford Dictionary of English (2010), page 1459 was first marketed in 1985 by Marlow Foods (named after Rank Hovis McDougall's headquarters in Marlow, Buckinghamshire), a joint venture between RHM and Imperial Chemical Industries (ICI), who provided a fermenter left vacant from their abandoned single-cell feed programme. The two partners invested in patents for growing and processing the fungus, and other intellectual properties in the brand. Quorn entered distribution in the UK in 1993, and was introduced to other parts of Europe in the 1990s, and to North America in 2002. The initial advertising campaign for Quorn featured sports personalities, including footballer Ryan Giggs, rugby player Will Carling, and Olympic runner Sally Gunnell.

BioAmber produced bio-based succinic acid from January 2010 to December 2014 at a large demonstration plant owned and operated by the Company's former joint venture partner, ARD. The demonstration plant operated at the 350,000 liter fermenter scale, which at the time was one of the largest scale fermentations among start-up companies in the field of bio-based chemicals. BioAmber claim to have gained extensive experience from operating this plant for five years and incorporated the learning and improvements into the design of its commercial plant in Sarnia, Canada. BioAmber established a joint venture with Mitsui & Co. to build and operate a bio-succinic acid plant in Sarnia, Ontario with a manufacturing capacity of per year, with BioAmber owning 60% of the venture.

Yeast were termed top or bottom cropping, because the yeast was collected from the top or bottom of the fermenting wort to be reused for the next brew. This terminology is somewhat inappropriate in the modern era; after the widespread application of brewing mycology it was discovered that the two separate collecting methods involved two different yeast species that favoured different temperature regimes, namely Saccharomyces cerevisiae in top-cropping at warmer temperatures and Saccharomyces pastorianus in bottom-cropping at cooler temperatures. As brewing methods changed in the 20th century, cylindro- conical fermenting vessels became the norm and the collection of yeast for both Saccharomyces species is done from the bottom of the fermenter. Thus the method of collection no longer implies a species association.

When a beer has been brewed using a cool fermentation of around , compared to typical warm fermentation temperatures of , then stored (or lagered) for typically several weeks (or months) at temperatures close to freezing point, it is termed a "lager". During the lagering or storage phase several flavour components developed during fermentation dissipate, resulting in a "cleaner" flavour. Though it is the slow, cool fermentation and cold conditioning (or lagering) that defines the character of lager, the main technical difference is with the yeast generally used, which is Saccharomyces pastorianus. Technical differences include the ability of lager yeast to metabolize melibiose, and the tendency to settle at the bottom of the fermenter (though ales yeasts can also become bottom settling by selection); though these technical differences are not considered by scientists to be influential in the character or flavour of the finished beer, brewers feel otherwise - sometimes cultivating their own yeast strains which may suit their brewing equipment or for a particular purpose, such as brewing beers with a high abv.
