Abstract: | The authors have carried out a series of studies on l-glutamic acid fermentation with a strain of Brevibacterium divaricatum nov. sp. in the previous papers.In this paper, some metabolism of l-glutamic acid and oxidative decomposition of several organic acids concerning the tricarboxylic acid cycle by the resting cells have been studied. The results suggest that l-glutamic acid is one of the final fermentative products of this bacterium, and the tricarboxylic acid cycle is working as a glutamic acid forming cycle.The presence of glucokinase, phosphoglucoisomerase, phosphofructokinase, aldolase, DPN-linked glyceraldehyde-3-phosphate dehydrogenase, and TPN-linked glucose-6-phosphate dehydrogenase in cell-free extracts of this bacterium was also demonstrated. |
