[Recruitment ability of Microcystis aeruginosa under low light-low temperature combination].

The responses of growth and PS II activities in Microcystis aeruginosa (FACHB 905) have been studied under a condition of low light-temperature combination use orthogonal experiment method. The contents and proportions of chlorophyll and carotenoid were determined by colorimetry, the PS II activities were assayed with a Water-PAM, and also, the photosynthesis recovery of M. aeruginosa was verified via reculture under a normal condition.
