fermentation

 [fer″men-ta´shun]
the anaerobic enzymatic conversion of organic compounds, especially carbohydrates, to simpler compounds, especially to lactic acid or ethyl alcohol, producing energy in the form of ATP.

fer·men·ta·tion

(fĕr'men-tā'shŭn),
1. A chemical change induced in a complex organic compound by the action of an enzyme, whereby the substance is split into simpler compounds.
2. In bacteriology, the anaerobic dissimilation of substrates with the production of energy and reduced compounds; the mechanism of fermentation does not involve a respiratory chain or cytochrome, hence oxygen is not the final electron acceptor as it is in oxidation.
[L. fermento, pp. -atus, to ferment, from L. fermentum, yeast]

fermentation

(fûr′mən-tā′shən, -mĕn-)
n.
Any of a group of chemical reactions induced by microorganisms or enzymes that split complex organic compounds into relatively simple substances, especially the anaerobic conversion of sugar to carbon dioxide and alcohol by yeast.

Judging from the comparison between biomass and the percentage of P(3HB) content resulting from the fermentation process using rice straw stew as a carbon source decreased biomass while the percentage of P(3HB) levels increased.
Cover liquors were formulated for each fermentation process to create finished products that equilibrated to the processor's desired product specifications such that cucumbers fermented in Ca[Cl.sub.2] and cucumbers fermented in NaCl would be stored as finished product with equivalent concentrations of NaCl, Ca[Cl.sub.2], vinegar, and flavors.
Thus, the aim of this research was to extract fermentable sugars from oil palm mesocarp fibers using alkaline pretreatment and enzymatic hydrolysis process and then to find the optimum parameter for biohydrogen production via light independent fermentation process.
Today, fermentation processes that use no antibiotics for bacterial control are less effective than those observed using Kamoran, the well known antibacterial agent already established in the market.
Surplus carbon supplies often have an effect on osmotic dehydration of microorganisms in an anaerobic fermentation process. A momentous rise in the ratio of butyrate to acetate is found in bio-butyric acid fermentation process with limited amount of glucose and C.
The RSM allows optimised mathematical models to be developed that can improve the quality of process; however, to improve production and optimise a fermentation process, to either increase yield or productivity, experimental studies must be conducted to observe the influence of the variables on the process (SILVA et al., 2008).
Typical applications would be: H2 generator cooling systems (power generation), H2 in heat treatment furnaces (metals), H2 in NH3, methanol or chlorine (chemical), CO2 in fermentation process (food), CO2 in biogas, H2 in blast furnace top gas (steel), H2 in hydrocarbons (petrochemical) or He recovery (industrial gas).
asserted that any raw material that contains hexose sugars or can be converted to these sugars can be used as the feedstock for fermentation process. Using corn as a substrate in fuel production is of benefits including relatively high production efficiency, vast geographical farming area, and a high ratio of energy output to input.
Penicillin fermentation process is a typical biochemical reaction process with the features of nonlinearity and dynamic, which is caused by the factors such as genetic variation of somatic cell, microbial sensitivity to environment changing, and instability of raw material and seed quality that bring about serious nonlinearity and uncertainty [20].
Butanol is commonly produced in acetone-butanol-ethanol (ABE) fermentation process. ABE fermentation process is one of the main biochemical processes of biofuel production which has found industrial application [5].
The process converts sugars into BDO in a patented direct fermentation process. Says Hartwig Meier, head of global product and application development for Lanxess' high-performance materials business unit, "This is a strong signal to the market and a tremendous step forward in our future plans to offer our Pocan in a biobased version.
