查询词典 green algae

Porphyridium cruentum were treated with some antibiotics which were used as genetic selected marks in genetic engineering. The results showed that the algae cells could resist high concentration of Penicillin,Streptomycin,Gentamicin and Kanamycin, without any influence at the dose below 100 u/mL of which can kill bacterium adhere to the algae cells . These antibiotics can be used to repress bacterium in purifying algae strain.Porphyridium cruentum is high sensitive to Erythromycin,Terramycin and Ofloxacin....
