Production of glutamic acid from glucose firstly gets oxidized to ketoglutaric acid, which in turn get aminated to produce glutamic acid and production of lactic acid from glucose by yeast and Lactobacillus lactis, production of -carotene jointly by (+) and (-) strains of either choaenophoracucurbitarum or Blakesleea trispora are three very good examples. In fermentation, the only energy extraction pathway is glycolysis, with one or two extra reactions tacked on at the end. Fermentation is the commonly used term to refer to a bioprocess carried out inside a bioreactor. The regulation of biosynthesis of secondary metabolites differs significantly from that of primary metabolites. It does not store any personal data. The first is simply to do with availability. During NADH regeneration, the two pyruvate molecules are first converted to two acetaldehyde molecules, releasing two carbon dioxide molecules in the process. Reaction conditions are mild, in aqueous media and most reaction steps occur in one vessel. Aerial photograph of coastal waters with blooms of sulfate-reducing bacteria appearing as large patches of green in the water. Fermentation allows glucose to be continuously broken down to make ATP due to the recycling of NADH to NAD+. Fermentation only produces two ATP per glucose molecule through glycolysis, which is much less ATP than cellular respiration. Lactic acid (i.e., lactate) fermentation occurs in some strains of bacteria and in skeletal muscle and produces lactic acid (i.e., lactate).
