A taxonomic study was performed on a strain of soil bacteria which grew in a medium containing methyl acetate as a source of carbon. Although this strain is considered to be consistent with Brevibacterium vitarumen (Knutsen) Breed in many characters, it does not fit Brev. vitarumen (Knutsen) Breed with respect to the production of acid from sugars. Accordingly, this strain was considered to be belong to the strain resembling Brev. vitarumen (Knutsen) Breed. This strain assimilates various esters, alcohols (except for methyl alcohol), and n-paraffin hydrocarbons (C_<12>-C_<17>). The optimum initial pH and optimum concentration of methyl acetate as a source of carbon for microbial growth were ca. 7.0 and 1.5vol%, respectively. When methyl acetate was used as a source of carbon, the strain required thiamine. The strain first hydrolyzed methyl acetate to methyl alcohol and acetic acid, and utilized only acetic acid as a source of carbon. In this experiment, the maximum specific growth rate was 0.170hr^<-1>. The microbial yield to methyl acetate was 0.341,but the value obtained for the acetate portion in the substrate was 0.438. The essential amino acid content of dry cell matter almost satisfied requirements as a food protein. The elementary analysis of these cells showed a nearly mean value, compared with other bacteria.
