Cyanobactenia may experience dormancy, recruitment and growth processes in response to temperature changes during seasonal alteration. The effects of temperature on the photosynthesis, growth and buoyancy regulation of two cyanobacteria, Microcystis flos-aquae and Planktothrix mougeotii, were investlgated in a batch culture experiment. M, flos-aquae could not grow below 13℃ , but grew slowly at 16℃, In contrast, P, mougeotii could grow slowly at 10℃ and grew well above 16℃, The growth rate of both algae increased with temperature from 10℃ ...
