利用小麦秸控制赤潮生物生长的研究

以球形棕囊藻为研究对象,探讨了小麦秸用于赤潮生物控制的可行性,研究了微生物、吸附作用在抑藻效应中的可能作用,运用扫描电子显微镜观察了小麦秸对藻细胞形态的影响,对小麦秸抑藻机理进行了分析和讨论。结果表明,小麦秸是一种比较理想的抑藻材料,无需微生物的降解,适度切割后能够吸附藻细胞、释放出抑藻活性物质,从而有效控制赤潮生物——球形棕囊藻的生长。抑藻活性物质的释放是小麦秸抑藻的主要机制。

Studies on wheat straw to inhibit the growth of Phaeocystis globosa

In order to explore the possibility that wheat straws were used to control HABs, the inhibition of wheat straws after physical disruption on the growth of Phaeocystis globosa was investigated.The possible mechanism was put forward though assessment of the roles of microorganism and adsorption of chopped straws, and morphological observation by SEM in the growth inhibition. The results shown that finely chopped straws have an excellent algistatic activity, adsorption of straws and inhibition compounds from the straws might be responsible for the inhibition.wheat straws may be a potential candidate for HABs control.
