Abstract

Highlights: Cultivation of microalgae Chlorella sp. with livestock waste compost was investigated. Biomass productivity ranged from 184.22 to 288.84 mg L −1 day −1 . As the initial nutrient concentration decreased, the lipid content increased. Lipid productivity ranged from 84.76 to 104.89 mg L −1 day −1 . The livestock waste compost medium with 2000 mg L −1 COD was optimal for algal growth. Abstract: Cultivation of microalgae Chlorella sp. with livestock waste compost as an alternative nutrient source was investigated in this present study. Five culture media with different nutrient concentrations were prepared. The characteristics of algal growth and lipid production were examined. The results showed that the specific growth rate together with biomass and lipid productivities was different among all the cultures. As the initial nutrient concentration decreased, the lipid content of Chlorella sp. increased. The variations in lipid productivity of Chlorella sp. among all the cultures were mainly due to the deviations in biomass productivity. The livestock waste compost medium with 2000 mg L −1 COD provided an optimal nutrient concentration for Chlorella sp. cultivation, where the highest productivities of biomass (288.84 mg L −1 day −1 ) and lipid (104.89 mg L −1 day −1 ) were presented.
