摘要: This chapter reviews current knowledge of the bio-synthetic pathways for four vitamins (riboflavin, bio-tin, folic acid, and cobalamin) in Bacillus spp. Biosynthesis these has been studied subtilis, sphaericus, megaterium. Riboflavin, also called vitamin B2, is unique among because more known about riboflavin (rib) biosynthetic genes B. subtilis than any other bacterium. The discusses organization regulation presents results from laboratory on how this information can be used to enhance production by subtilis. molecular genetics enzymology biosynthesis biotin, B8 or H, bacteria have extensively. Enzymatic steps acid enteric extensively are outlined. focuses recently characterized involved biosynthesis. Vitamin B12, a complex organic molecule, largest all vitamins. Most genetic B12 cobalamin comes studies Salmonella typhimurium.
