查询词典 experiments

We selected copper chlorophyll and copper sodium chlorophyllin to have experiments of culturing microalga, under the same of illumination and the concentration of nutrition, comparing with copper ion. The results show that under the condition of illumination, a certain quantity of photosensitizer can produce a great quantity of active oxygen, which has strong effect of death; Copper chlorophyll and copper sodium chlorophyllin have very strong influence to growth of microalga.
