The objective of this study was to find a cheap, nutrient rich alternate to cultivate freshwater microalgae. Materials and Methods: Vermiwash at a concentrations of 25, 50, 75 and 100% were used to cultivate microalgae isolated from fresh water habitats. Specific growth rate and biomass concentrations were determined to evaluate the effect of vermiwash medium in comparison with Bold’s basal medium. Results: A total of 13 microalgae that belonged to the family Cyanophyceae and Chlorophyceae were isolated. Growth rate and biomass of microalgae were increased with higher concentrations when the vermiwash was used at a concentration of 25, 50 and 75%. At the same time, both the parameters were declined in undiluted vermiwash indicating the algal growth inhibition under high levels of nutrients. Conclusion: Utilization of vermiwash is feasible to cultivate fresh water microalgae thereby fulfilling the nutrient requirements and reducing the use of inorganic fertilizers.]]>Varela, J.C., H.
