Abstract：This study focused on the impacts of trace elements copper (Cu) and molybdenum (Mo) on the growth of Microcystis aeruginosa,researching the growth of algae by measuring the biomass and total sugar content of culture medium which contains trace elements Cu(Ⅱ)and Mo(Ⅵ) with different concentrations.The results show that when the concentration of Cu(Ⅱ) and Mo(Ⅵ) are 10 μg/L and 50 μg/L,the condition of Microcystis aeruginosa is the best,with the biggest in the maximum biological existing amount and the maximum total sugar content.Result of correlation analysis shows a good correlation between sugar content of biological biomass and the growth of algae,and the correlation is more significant with a good condition of algae.The influence of trace elements Cu,Mo on the growth of Microcystis aeruginosa is not consistent with the traditional kinetic models by growth kinetics analysis,and through the curve fitting an equation is given about trace elements influence on growth of Microcystis aeruginosa.
