Fermentation a process traditionally known for the anaerobic conversion of sugar to carbon dioxide and alcohol by yeast now refers to an industrial process of manufacturing a wide variety of metabolites and biomaterials by using microorganisms or mammalian cells in a controlled culture environment Fermentation in food processing is the process of converting carbohydrates to alcohol or organic acids using microorganisms—yeasts or bacteria—under anaerobic conditions Fermentation usually implies that the action of microorganisms is desired The science of fermentation is known as zymology or zymurgy The term fermentation sometimes refers specifically to the chemical conversion of

Enhanced Sorbitol Production under Submerged Fermentation using Lactobacillus plantarum Several process variables were evaluated on sorbitol production including carbon sources (glucose fructose maltose sucrose) carbon concentrations (5 10 20 and 25 g l-1) nitrogen sources (peptone tryptone yeast extract beef extract and organic nitrogen mix) temperatures (25 29 33 37 41C

Enhanced ethanol production from Kinnow mandarin

01/01/2011Simultaneous saccharification and fermentation (SSF) is considered an ideal process for ethanol production because of its inherent advantages which include use of a single vessel for saccharification and fermentation a very low probability of catabolite repression the simplicity of operation low capital investment and improved process economics (Faga et al 2010 Hari Krishna et

Thereafter the production phase was initiated by supplementing fructose and switching to anaerobic conditions by discontinuing aeration and decreasing the speed of agitation The strategy of two-stage fermentation significantly enhanced the production of mannitol up to 240 g l⁻ which is the highest among all fermentative production processes and corresponds to 81 % yield and 4 g l⁻ h

The History and Fermentation Process of Lager Beer All beers are made of ale or lager which are the two main branches of the beer Ales are thousands of years older than the lager beer The lager beer type is different from the ale beer and other types of beer it is rich and more natural in taste Most beer consumers consider it to be of more premium quality than any other type of beer

Studies on the production of L-arginine by fermentation using mutants of Corynebacterium (Brevibacterium) Bacillus and Serratia have been conducted since the 1960s More recently the breeding of L-arginine production strains by gene recombination techniques using Escherichia coli has been investigated To produce L-arginine efficiently by fermentation it is necessary to breed strains
