In orfer to find out an organism to be used for the fermantative production of glutamic acid, samples of soil and sewage were collected from various parts of Taiwan. Of 2522 strains isolated from 458 samples, 94 formed 1-glutamic acid at a yield of more than 5% from glucose. These were further subjected to the screening with locally available materials as culture media. Sixteen strains out of 94 were able to produce more than 10% of the acid from glucose, and 5 of them gave a yield of more than 20%. These strains were stabilized through repeated plate cultures in the productivity of 1-glutamic acid.From the culture broth of strain No. 1942,the crystals of 1-glutamic acid were isolated, and then confirmed by the analytical data showing the known constants of this acid.
