摘要:
Static tests were conducted to study and analyse the growing situation of M. aeruginosa and variation of dissolved total phosphorus in medium under laboratory condition. The results shows that the higher is the concentration of exogenous phosphorus, the longer log phase does M. aeruginosa have. The limiting concentration of phosphorus for growth of M. aeruginosa is O.lmg/L. As cultured with different phosphorus source, the specific growth rate of M. aeruginosa decreased in the following order K2HPO4> NaH 2PO4>Na3PO4. K2HPO4 is easily used for M. aeruginosa growing. © 2011 IEEE.
