Isolation and identification of obligately anaerobic bacteria in kusaya gravy obtained from a manufacturer in Niijima Island was carried out. The number of anaerobic viable cells in the gravy using GasPak anaerobic system was approximately 107/ml.Of 20 strains isolated from BP5C medium, 19 strains were confirmed to be obligate anaerobes and used for experiment.The 8 strains which can grow well on BP5C and modified GAM agar media among test strains were identified as genus Peptostreptococcus (5 strains) and genus Sarcina (3 strains). The remaining 11 strains which cannot grow well on the agar media were classified according to gram reaction, spore formation and morphological characteristics into genus Sarcina (8 strains), genus Clostridium (2 strains) and unidentified gram-positive rod (1 strain).
