抗菌素对海洋微藻静置培养生长和保存的影响

The Effects of Antibiotics on Growth and Restoration of Marine Micro-algae

分别用不同的抗菌素处理常用的海洋微藻 ,观察对海洋微藻生长和保存的影响。结果表明：青霉素在开始 2 d内对三角褐指藻有抑制作用，在 5 d之后抑制作用不明显，青霉素有利于湛江等鞭藻、等鞭藻和亚心形扁藻的生长。硫酸链霉素在开始 5 d内对三角褐指藻、扁藻、湛江等鞭藻、等鞭藻在不同程度上有抑制作用。硫酸庆大霉素在一定程度上有利于湛江等鞭藻、等鞭藻生长。氯霉素在较高浓度时能抑制湛江等鞭藻、等鞭藻生长。青霉素、硫酸链霉素在湛江等鞭藻、等鞭藻的保存中有一定的作用。以青霉素和硫酸链霉素共同处理的效果最好。

Marine micro-algae were treated with different concentration of antibiotics and the effects of antibiotics on growth and restoration was observed. Penicillin could inhibit growth of Phaeodactylum tricornutum Bohl in 2 days. The inhibition decreased after 5days. Penicillin could accelerate the growth of Isochrysis Zhanjiangensis Hu＆ Lui sp.nov, Isochrysis galbana Parke and Platymonas subcordiformis increased in the present of Penicillin. Streptomycin can be inhibit growth of Platymonas subcordiformisin , Isochrysis Zhanjiangensis Hu＆ Lui sp.nov, Isochrysis galbana Parke and Phaeodactylum tricornutum Bohl, in different degree. Dingdameisu could promote the growth of Isochrysis Zhanjiangensis Hu＆ Lui sp.nov, Isochrysis galbana Parke in some degree. Chloramphenicol could inhibit growth of Isochrysis Zhanjiangensis Hu＆ Lui sp.nov, Isochrysis galbana Parke. Penicillin and Streptomycin were important in restoration of Isochrysis Zhanjiangensis Hu＆ Lui sp.nov, Isochrysis galbana Parke.
