| The effects of 6 biocides on the growth of Chlamydomonas reinhardii in pure culture were studied. For the batch culture assay of biocides, the growth rate in control tubes should be compared with in the test tubes and the effective concentration calculated on the basis of the percent decrease in growth rate at the different toxicant concentration. The concentrations at which 50% decrease in growth rate was observed are $40{mu}g$/l for butachlor and $350{mu}g$/l for alachlor in herbicide, $900{mu}g$/l for phenazine-5-oxide and $3,400{mu}g$/l for isoprothiolane in fungicide, and $3,330{mu}g$/l for fenthion and $332,500{mu}g$/l for trichlorfon in insecticide. The inhibitory effect on the growth of Chlamydomonas reinhardii by the treatment of various biocide concentrations was decreased in order of herbicide>fungicide>insecticide. Chlorophyll and carotenoid content per cell were increased, whereas chlorophyll a/b ratio was hardly affected by biocides. The effects of biocides on pigment content were also decreased in order of herbicide>fungicide>insecticide, which suggested the relationship between the effect of biocides on the pigment content and inhibition of growth rate. |
