Abstract
In order to study the algae-dissolving effect of algae-lysing bacteria S7 on cyan bacteria, the algae-alkali test was carried out on bacteria S7 grown for 24 hours. The algae-alkali bacteria with different volume fractions were added to observe the algae-dissolving effect. The experimental results show that the occurrence of algae action has a lower limit on the volume fraction of bacteria S7, and only when this lower limit is reached or exceeded; there is obvious algae-dissolving phenomenon. When the lower limit is reached, the algae-dissolving phenomenon is delayed or not obvious. When the lower limit is reached, the algae-dissolving phenomenon is delayed or not obvious. The larger the initial volume fraction is, the more obvious the algae-dissolving phenomenon and the shorter the algae-dissolving time are. In order to achieve better algae-removing effect, the dosage ratio of bacterial S7 was determined to be 1:10.
