| Abstract | The levels of different organic carbon supplements in a mixotrophic culture were optimised to enhance biomass and lipid accumulation in Scenedesmus sp. AARL G022. The supplement nutrients, viz. glucose, glycerol and sodium acetate, were compared with non-organic carbon supplement (photoautotrophic culture). The most suitable carbon source was found to be 0.05M glucose, giving a yield of 2.78 ? 0.86 g.L-1 of biomass and 233.68 ? 35.34 mg.L-1 of crude lipid. The highest yield of biomass (4.04 ?0.36 g.L-1) was obtained from a light-dark cycle of 24:0 hr. The highest crude lipid yield of 396.35 ? 11.60 mg.L-1 was obtained from a light-dark cycle of 16:8 hr. The optimized condition for culturing Scenedesmus sp. AARL G022 is to cultivate it under a mixotrophic condition using 0.05M of glucose supplement with a light-dark cycle of 16:8 hr. |
