抗菌素对海洋微藻静置培养生长和保存的影响

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2d内对三角褐指藻有抑制作用，在5d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5d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。

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

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