Abstract/Description: | In this study, the effect of textile dye (Optilan Red) toward microalgae Chlorella vulgaris was monitored for a period of 96 hours. The parameters such as specific growth rate (SGR), EC50, protein, chlorophyll, carotenoid and elemental composition of the microalgae were recorded. Results showed that SGR for C. vulgaris decreased with increase in concentration of dye and a significant decrease was noticed upto 20 ppm however, further increase in concentration showed no growth of the organism. EC50 for Optilan Red was found to be 23.16 ppm. The protein level of treated C. vulgaris showed significant reduction in all the concentrations. Further significant increase in percentage protein inhibition was noticed with increase in dye concentrations. More than 50% reduction in level of both pigments evident at 50 ppm. Maximum percentage inhibition was 66.6% and 79.4% for total chlorophyll and carotenoid, respectively (at 50 ppm). It was noticed that elemental composition of C. vulgaris was reduced significantly as compared to the control. This study emphasizes that assessment of toxicity of textile dyes towards photoautotrophic organisms including micro-algae is of prime importance to assess the impacts of dye pollution in aquatic environment. |
