Abstract
A bacterium strain (K-173-10) which was isolated from waste soil of Korea brewing factory, could be grown on acetate as the sole carbon source and accumulated a considerable amount of L-glutamic acid in the medium. This strain was identified as the new species Brevibacterium ammoniagenes. This study was concerned not only with the culture condition for the production of L-glutamic acid and the cell growth, but also with the effects on concentration of various kind of organic substances, growth factors and penicillin. The results obtained were summarized as follow; 1. It was found that the concentrations of acetate and ammonium ions affected the growth of the bacterium as well as its L-glutamate accumulation. The optimum conditions of the composition of grown media for the growth of the bacterium and its glutamic acid production was found to be 40 g/l of total acetate,
