| | Process for producing 5'-inosinic acid by fermentation - Patent 5164306 |
 | | A process for producing 5'-inosinic acid by culturing 5'-inosinic acid-producing bacteria in a medium containing inosine, and cane molasses, sucrose or glucose as the main carbon source and containing at least one of L-methylglycine, N,N-dimethylglycine, N,N,N-trimethylglycine and (2-hydroxyethyl)trimethylammonium in an amount effective to enhance the yield of 5'-inosinic acid, and harvesting the 5'-inosinic acid produced. |
| | L-Amino acids such as L-glutamic acid, L-lysine, L-glutamine, L-arginine, L-phenylalanine, L-threonine, L-isoleucine, L-histidine, L-valine, L-serine, L-ornithine, L-citrulline, L-tyrosine, L-tryptophane and L-leucine, etc. and 5'-inosinic acid have hitherto been produced by fermentation using microorganisms belonging to the genus Brevibacterium, the genus Corynebacterium, the genus Bacillus or the genus Escherichia, etc. in an industrial scale. |
| | Further, in the L-amino acid fermentation using choline as a main carbon source, choline is used as only one main carbon source and the yield of L-amino acid is merely trace. |
