Mangrove PSB:Isolation,Culture and Phosphate-dissolving Ability

Ten phosphate solubilizing bacterial(PSB) strains were isolated from the mangrove rhizospere.The culture condition of the selected most effective strain ZB0211 was examined from 4 aspects.The experimental results showed that the optimal carbon and nitrogen sources were respectively sucrose (10 g·kg-1) and NH4Cl ((1 g·kg-1)),the optimal concertration of NaCl was 1%,and optimal pH 7.5.The potential relationship among pH level,bacterial rowth and phosphate-dissolving ability was also discussed.
