摘要
从富营养化湖泊分离获得的 1株菌 (B5) ,具有明显的溶藻效果。通过凝聚、细胞裂解和生物降解作用能有效去除鱼腥藻细胞。B5菌可能是通过直接接触导致藻细胞的凝集及进一步的生物降解 ,同时存在一种具有热稳定性且能抑制藻类细胞生长的胞外分泌物。
The growth inhibition of cyanobacteria by bacterium (strain B 5) was st udied. The results show that one strain of bacterium (strain B 5) with obviousl y algae-lytic can be separated from the eutrophic lake. It can effectively remo ve Anabaena by coagulation, cell lysis and biodegradation. The flocculation and further biodegradation of Algae cell was preformed through the direct contact of strain B 5 and its thermo-stability and algae growth inhibitive extracellular secretory compounds.
