8种微藻抗菌活性研究Antimicrobial Activities in8Species of Microalgae
江红霞,郑怡
摘要(Abstract)：
实验室培养的 3种海洋微藻和 5种淡水微藻 ,用甲醇和甲苯 ( 3∶ 1 )混合液进行提取 ,亚心形扁藻和紫球藻还另用乙醚和丙酮 2种溶剂进行了提取 .提取物用圆形纸片法对 4种细菌和 3种真菌的生长进行了抑制实验 ,结果表明 :在 8种微藻中 ,有 2种微藻 (铜绿聚球藻和塔胞藻 )的抗菌谱最广 ,分别对 4种菌的生长有抑制作用 .铜绿聚球藻的甲醇和甲苯 ( 3∶ 1 )提取物对枯草芽孢杆菌的抗性最强 .在所有的菌中 ,黑曲霉对微藻提取物最敏感 .不同的微藻对革兰氏阳性菌和革兰氏阴性菌有不同的抑制作用 .微藻对细菌的抑制作用大于对真菌的抑制作用
关键词(KeyWords)： 微藻;提取物;抗细菌活性;抗真菌活性
