| Abstract | A strain of Azotobacter species was isolated from the surface sea water of Kwang-yang Bay in Korea and was identified as Azotobacter insignis. In order to reveal the natural habitat of this microorganism, growth at various salt concentrations was tested with the result of 3% NaCl beings optimum. Only slight growth was detected in the absence of NaCl. This result was thought to prove (in part) that the natural habitat of the strain dealt with is sea water. Fairly good growth was obtained at 6% NaCl concentration. The study of effects of salt on the growth of this strain to various temperatures and pHs has shown that temperature 30℃ and pH 7.0 are Optimum. | ||
