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。

关键词: 溶藻菌, 溶藻微生物, 凝聚, 细胞裂解, 生物降解

Abstract: The growth inhibition of cyanobacteria by bacterium (strain B5) was studied. The results show that one strain of bacterium (strain B5) with obviously algae-lytic can be separated from the eutrophic lake. It can effectively remove Anabaena by coagulation, cell lysis and biodegradation. The flocculation and further biodegradation of Algae cell was preformed through the direct contact of strain B5 and its thermo-stability and algae growth inhibitive extracellular secretory compounds.

Key words: algae-lysing bacteria, algae-lysing microorganism, coagulation, cell lysis, biodegradation
