【Abstract】 Porphyridium purpareum was inoculated in five different nitrogen resources which contained same quantity of nitrogen. The effects of five different nitrogen resources on Porphyridium purpareum growth were observed. The results indicated that : nitrate can improve Porphyridium purpareum cell’s growth; ammonium salt was disadvantage to its growth and the effects of urea on Porphyridium purpareum growth were between that of nitrate and ammonium.更多还原
