Study on Growth Pattern of Typical Cyanobacteria and Chlorophyta in Urban Water Bodies of Beijing under the Heat Wave Scenarios
Taking Beijing urban water as medium,the effects of the growth pattern of Microcystis aeruginosa and Chlorella pyrenoidosa at different levels of temperature and alkalinity were studied under the heat wave scenarios.The results showed that Microcystis aeruginosa had strong abilities to adapt to the change of temperature and alkalinity,and its optimum growth temperature was 35 ℃,and it was better to grow when added the alkalinity of 10 mmol/L.The tolerance of Chlorella pyrenoidosa for high temperature was worse than Microcystis aeruginosa,and the optimum temperature of Chlorella pyrenoidosa was 30 ℃.In addition,low alkalinity level promoted the growth of Chlorella pyrenoidosa when the temperature was low.With the increasing of temperature,improving the alkalinity of water was needed to ensure the strong proliferation of Chlorella pyrenoidosa at the same time;otherwise it would produce a certain degree of inhibition.
