英文摘要	Little is known about interactions of iron with temperature, light, nitrate and ammonium on physiology of the freshwater species Microcystis aeruginosa (Cyanobacteria). Results showed that growth and photosynthesis of M aeruginosa were inhibited by Fe limitation in all cultures beside nitrogen-treatment groups. Relatively low or high temperature and light intensity could impair the growth and photosynthesis of M aeruginosa despite Fe concentration in media. Under Fe-replete conditions, both the OD665 and chlorophyll a reached peaks at 30 degrees C and light intensity of 30 mu mol photons m(-2) s(-1). Nitrate is proven to be the main nitrogen source for growth of M. aeruginosa collected from Lake Dianchi. Yield, ETRmax, alpha and I-k also reached highest values at light intensity of 30 mu mol photons m(-2) s(-1) and high FeNO3- conditions, but at a temperature of 20 degrees C. Our results can be used to help control blooms of M. aeruginosa in Lake Dianchi and other water-bodies.
