The relationship between bacteria and microalgae in water environment and its practical application

The relationship between bacteria and microalgae and its action mechanism was summarized. The progress in research on the following aspects was addressed: inhibition effect of bacteria against harmful microalgae; inhibition effect of microalgae against pathogenic bacteria; the application research situation of bacteria and microalgae in water purification. Aiming at the aquaculture we put forward suggestions for the research on the relationship between bacteria and microalgae and its development and application.
