摘要
从西太湖梅梁湾分离出野生水华微囊藻，得到水华微囊藻在半固体培养基上的纯藻株研究太湖水华微囊藻在室内不同氮、磷浓度下的生长特征，发现在氮浓度为 １７ｍｇ，Ｌ^（－１），磷浓度为１７ｍｇ·Ｌ^（－１）左右时，微囊藻日增长率最大比较自然状态和室内培养条件下微囊藻的生长情况，可知野生微囊藻一般能形成较大的群体，室内液体培养基的营养盐浓度远高于野外，却难以得到大群体微囊藻，从此实验结果来看，营养盐浓度与微囊藻大群体的形成似乎无直接关系．
This study deals with the growth characters and pure culture of Microcystis from Taihu Lake. It is found that Microcystis flos-aquae can grow in solid medium. The results also show that both phosphorus and nitrogen play an important role during the growth period of Microcystis flos-aquae. The maximum growth rates appear when the PO_(4~3)- concentration reach 1. 7 mg' L^(- 1) and the TDN concentration reached 17 mg' L^(-1). Comparing the indoor culture of Microcystis with the Microcystis in the lake, there is a clear difference in their growth characters. The Microcystis in the lake normally appears as big colony while it appears only single cell or small colony with ten cells in indoor culture.
