利用放射性P（32 P）和绿色荧光蛋白标记的假单胞菌，研究了铜绿微囊藻（Microcystis aeruginosa）与附着的假单胞菌（Pseudomonas）之间的磷转移。M.在个别实验中，磷饥饿条件下的铜绿假单胞菌对水体中32 P的吸收率最高（70%），而32 P饱和条件下的铜绿假单胞菌对水体中32 P的吸收率约为50%。而32 P饱和的M.将铜绿假单胞菌转移至P-饥饿细菌。饥饿的M。铜绿假单胞菌对磷的吸收能力优于细菌，在以细菌为生物磷源的组合培养中，铜绿假单胞菌的生长速率和丰度均高于细菌。磷从细菌向蓝藻的转移速率较慢。P周期主要在M之间。铜绿假单胞菌和假单胞菌在水中变化不大。这种能力对M.铜绿假单胞菌，特别是如果水中的磷酸盐浓度低，在水华期间。
Phosphorus (P) transfer between Microcystis aeruginosa and the attached bacterium Pseudomonas was studied using radioactive P (32P) and green fluorescence protein-labeled Pseudomonas. M. aeruginosa in P-starved condition took up most 32P (70%) in water and about 50% of 32P in 32P-saturated bacteria in individual experiments. However, only 26% of 32P in the 32P-saturated M. aeruginosa was transferred to P-starved bacteria. The P-starved M. aeruginosa had an advantage to take up P over the bacteria and its growth rates and abundance were higher in combined cultures, with bacteria as the biotic P source. The rate of P transfer from bacteria to the cyanobacteria was slow. P cycles predominantly between M. aeruginosa and Pseudomonas with little variation in the water. This ability is very useful for the colony-forming M. aeruginosa, especially if phosphate concentrations in water are low during water bloom periods.
