ABSTRACT
Toxic effects of L7 lyophilized powder of extracellular active components (L7-LPEAC), extracted from the Algae-lysing bacteria L7, on Chlorella pyrenoidosa were studied according to the changes of effective photosynthesis rate (EPR), the protein content, the chlorophyll a content and the MDA content of algae. The results showed that the growth of alga was promoted at low concentrations of L7-LPEAC (0.80 g/L, 1.25 g/L). The 96 h-EC50 and 120 h-EC50 upon Chlorella pyrenoidosa are 5.75 g/L and 2.55 g/L, respec tively. The chlorophyll a content increased firstly and then decreased at high concentrations of L7-LPEAC (≥2 g/L), so did the protein content. Compared with the control group, there is a significant statistics diff erence (P
