摘要
以分光光度法测定3株溶藻菌(AL-1、AL-6和AL-8)对水华鱼腥藻(Anabaena flos-aquae)生长效应和光合色素的影响。结果表明:3株溶藻菌均能显著抑制水华鱼腥藻的生长,对其生长速率、干重的抑制效应明显,并表现出一定的浓度相关性;且3株溶藻菌均能影响水华鱼腥藻的色素吸收光谱。3株溶藻菌溶藻方式略有不同,AL-1和AL-6可以通过分泌热稳定的物质和热不稳定的物质间接起到溶藻效果,而AL-8可同时通过直接和间接方式溶藻。
The effects of 3 algae-lysing bacterial strains （AL-1, AL-6 and AL-8） on the growth and photosynthetic pigments of Anabaena flos-aquae were determined by spectrophotometry. The results showed that all the 3 bacterial strains could significantly inhibit the growth of A. flos-aquae and their inhibiting effects had a certain correlation to their concentrations. Also the 3 bacterial strains could in- fluence for A. flos-aquae ＇s pigments to absorb light spectrum. The 3 bacterial strains were somewhat different in algae-lysing mode.AL-1 and AL-6 indirectly played an algae-lysing role through secreting heat-stable and heat-labile substances while AL-8 played an algae-lysing role directly and indirectly.
