Among them, tiny pale pinkish colonies were composed mainly of a filamentous bacterium, which was identified as Flexibacter sp. on the basis of bacteriological characterization. The isolates of Flexibacter sp. formed very tiny circular colonies on Z-CII agar, but they produced large thin rhizoidal colonies on yeast extract-enrichment solution (YES) agar. The agar media containing various kinds of peptones, sugars, organic acids or nucleic acid bases yielded very slow growth of bacterial colonies as compared with those on YES agar. The isolates were shown to have an essential vitamin B_<12> requirement for growth. Maximum growth yield of the isolates was observed at 26℃ and they could not grow above 40℃.}, pages = {15--22}, title = {シャトネラ・マリーナの保存株から分離されたフレキシバクターの増殖挙動}, volume = {44}, year = {} }
