利用九龙江口、黄河口悬浮物和厦门湾、泉州湾近岸表层沉积物作为磷源，用分批培养法培养中肋骨条藻（Ｓｋｅｌｅｔｏｎｅｍａｃｏｓｔａｔｕｍ），聚生毛角藻（Ｃｈａｅｔｏｃｅｒｏｓｓｏｃｉａｌｉｓｔ），小球藻（Ｃｈｌｏｒａｌｌａ），均可正常生长，说明在磷饥饿状态下，样品中潜在生物可利用磷可转化并释放到水相，以供藻类生长之需．培养体系中藻类对磷的摄取与磷自样品中的转化释放处于动态平衡状态．藻类在稳定生长期大量排出胞外产物．胞外产物中的强螯合基团与样品中铁等金属元素的络合作用，是培养体系中潜在生物可利用磷转化释放的可能机制之一．
Using the surface sediments from the Jiulongjiang estuary, the Yellow River estuary suspended sediment, and the coastal surface sediments of Xiamen Bay and Quanzhou Bay as the phosphorus source, Skeletonemacostatum, Chaetocerosocialist and Chlorella Chloralla, all grow normally, indicating that under starvation conditions, potentially bioavailable P in the sample can be converted and released into the aqueous phase for algae growth. Algae in culture system of phosphorus uptake and phosphorus from the sample transformation and release in a state of dynamic equilibrium. Algae excrete extracellular products in a steady growth phase. The complexation of strong chelating groups in extracellular products with metal elements such as iron in the sample is one of the possible mechanisms for the conversion and release of potential bioavailable phosphorus in culture system.
