種々の温度における塩濃度と好塩性細菌の増殖との関係

Incubation temperature was shown to have an effect on the optimal concentration of NaCl in forty-eight strains isolated from solar salt. Of these, twenty-one strains did not grow in 5% NaCl at 35°C, but grow at 27°C and 22°C. These mainly belonged to the genus Flavobacterium. The remaining six strains were unable to grow in less than 10% NaCl at 35°C, in spite of growing in 10% NaCl at 27°C and 22°C. These belong to the genus Brevibacterium. The optimal concentration of NaCl in some strains among the Brevibacterium and Flavobacterium was found to decrease with lowering temperature.
