Among 21 amino acids, dl-glutamic acid, dl-isoleucine, dl-leucine, dl-serine, dl-threonine, dl-tryptophan and l-tyrosine were found to be essential for the growth of Hiochi-kin in synthetic non-alcohol medium, while l-arginine, 1-cystine (or l-cysteine), l-histidine and dl-phenylalanine exerted a stimulative action on the growth of bacteria. The relation between the amount of amino acid and bacterial growth was examined; the prescribed concentrations [This Journal, 31,502 (1953)] of dl-glutamic acid, dl-isoleucine, dl-leucine, dl-tryptophan and l-tyrosine were sufficient for the bacterial growth, while in the lower part of the response curve of dl-serine there was found a lag section, and dl-threonine (over 200 μg. per ml) was rather inhibitory. In alcohol-containing medium, Hiochi-kin T 107 likewise required several amino acids which were necessary in non-alcohol medium.
