H strain isolated from Microcystis aeruginosa in the Taihu Lake. The results indicated that within the experimental scope the factors affecting the growth of Bacillus sp. H strain were arranged in the order: organic carbon>temprature>phosphate>ammonium. Of the four factors, organic carbon and temperature most significantly affected the growth of Bacillus sp. H strain. It was also found that with the raising of temperature, concentration of organic carbon or the ratio of N/P, the growth of Bacillus sp. H strain would become better. The optimum conditions for the growth of Bacillus sp. H strain in this experiment were:temperature 30℃, concentration of ammonium 0.520 g/L , concentration of peptone 2.0 g/L , phosphate 0.088 g/L , and organic carbon 2.28 g/L. Fig 4, Tab 2, Ref展开更多
