L-glutamic acid fermentation

Abstract

A study was made on the differences between Brevibacterium thiogenitalis No. 653 and its oleic acid-requiring mutant D-248 in some physiological characteristics. The most important difference of the characteristics was found in their intracellular fatty acid contents. Namely, the cellular oleic acid content of D-248 was scarcely affected by biotin but limited by the oleic acid which was added to the medium. On the other hand, various enzyme activities and rates of oxygen uptake for several organic acids were found to be slightly different between the two strains. These observations suggest that oleic acid has an important role for the production of L-glutamic acid. © 1967, Japan Society for Bioscience, Biotechnology, and Agrochemistry. All rights reserved.
