摘　　要：对程海螺旋藻玻璃温室 -半封闭跑道式循环培养池中的细菌进行研究 ,结果发现 ,细菌总数通常为10 4 ～ 10 7个 /mL ,并且随培养时间呈一定规律性波动 ;池子报废与细菌总数有一定关系 ,与藻种抗逆性及水环境的富营养化关系更大 ;经鉴定 ,优势菌为奈瑟氏球菌属 (Neisseria)、葡萄球菌属 (Staphylococcus)、微球菌属(Micrococcus)、肠杆菌科 (Enterobacteriaceae)等 ;少数菌株能明显抑制或促进螺旋藻生长 ,主要是通过其代谢产物作用于藻体 ;对 5株菌进一步研究表明 ,其最适生长温度为 37℃或 2 5～ 37℃ ,pH7～ 9。Bacteria in the spirulina culture pools in Chenghai were reported,which showed that the enumeration of total bacteria is 10 4—10 7/mL,the enumeration curve showed certain regularity with the culture time.The pollution of spirulina had major relation to the resistance of its species & the nourishing of cultivating water,and certain relation to the total bacteria enumeration.After identification,the dominant bacteria were Neisseria,Staphylococcus,Micrococcus ,Enterobacteriaceae and so on.A few strains obviously inhibited or promoted the growth of spirulina chiefly through their metabolite;the research of 5 strains showed that,the best growth conditions were 37℃ or 25—37℃,pH 7—9,which were conformed to the cultivating environment of Chenghai.
