Effect of phosphorus on the production of microcystin].

Effect of phosphorus on the production of microcystin was researched. The effects of soluble reactive phosphorus (SRP) on the growth of cells and on the production of Microcystin were studied. In addition, the efficiency of four different phosphorus compounds was researched. The results showed that microcystin increased with the increase of SRP, and c(TP) = 0.55 mg x L(-1) was the best growth concentration. When c(TP) < or = 0.55 mg x L(-1), the microcystin production increased with the increase of phosphorus concentration and was the lowest without phosphorus. Moreover, when c(TP) > 0.55 mg x L(-1), the microcystin was restrained by the content of phosphorus. At the same time, the effects of three inorganic substance of different phosphorus forms (K3PO4, K2HPO4, and KH2PO4) were no significant difference, but their effects on the production of microcystis were larger than organic phosphorus of sodium beta-glycerophosphate (GP).
