Abstract
- Various phosphatesolubilizing bacterial strains were isolated from the Hippochaete ramo sissimum rhizosphere in Tongguanshan copper tailings in Tongling of Anhui Province, East China. After many times of screening and purification, a strain B25 with stronger phosphatesolubilizing ca pability was obtained, which belonged to Bacillus genus, as identified by transmission electron microscope and DNA molecular approaches. A culture experiment was conducted to study the phosphate-solubilizing capability of the B25 within 168 h and the variations of the medium pH and B25 growth as well as the phosphate-solubilizing capability of B25 under different culture conditions. A weak correlation was observed between the phosphate-solubilizing capability of B25 and the medium pH. The B25 displayed a better phosphate-solubilizing capability when the carbon source was glucose, medium initial pH was 7. 0, and culture temperature was 30 °C. [ABSTRACT FROM AUTHOR]
