Chlorella vulgaris cultivation in photobioreactor using municipal wastewater for biofuel
746-752Microalgae, with their potential applications, particularly in food industry and Livestock feed as well as biofuel, has
gained considerable attention in recent decades. As their culture using commercial media is expensive, an integrated
approach using municipal wastewater is considered for simultaneous biomass production. Therefore, in this study, we
evaluated the growth and biochemical composition of the green microalgae Chlorella vulgaris grown in municipal
wastewater. Cultures in vertical column photobioreactor in outdoor/indoor conditions were also compared. C. vulgaris
showed significantly higher (P <0.05) cell density, biomass, specific growth rate, lipid and carbohydrate in indoor culture
condition than outdoor comparatively. Saturated fatty acids and polyunsaturated fatty acids containing 14-18 carbon
molecules were significantly higher (P <0.05) in indoor culture. The result suggests that wastewater could be used as a low
cost medium to grow C. vulgaris to obtain higher biomass and lipids
