Coupling dye degradation and biodiesel production by Geitlerinema sp TRV27. Indian Journal of Biochemistry and Biophysics. 2019 Aug; 56 (4): 309-3150975-09590301-1208http://imsear.searo.who.int/handle/123456789/190057In this study, the dye degrading the ability of marine cyanobacteria, Geitlerinema sp TRV27 was tested against the textile dye Acid black 52. Optimum conditions like pH, temperature, dye concentration for acid black 52 dye degradation were studied and were found to be pH 7, 25±2°C. More than 50% of degradation was observed for the tested maximum dye concentration, 100 ppm. The degraded dye intermediate was found to be naphthalene by GC-MS analysis and their toxicity on seed germination was studied. The dye treated biomass was used for the production of biodiesel and the physicochemical properties of biofuel were found to be within the standard limits.Journal ArticleIndiaDepartment of Biotechnology, Sathyabama Institute of Science and Technology, Chennai- 600 119, Tamil Nadu, India
