The Cost

The need for clean and low-cost algae production demands for investigations on algal physiological response under different growth conditions. In this research, we investigated the growth, biomass production and biochemical composition of Chlorella vulgaris using semi-continuous cultures employing three growth media (LC Oligo, Chu 10 and WC media). The highest cell density was obtained in LC Oligo, while the lowest in Chu medium. Chlorophyll a, carbohydrate and protein concentrations and yield were highest in Chu and LC Oligo media. Lipid class analysis showed that hydrocarbons (HC), sterol esthers (SE), free fatty acids (FFA), aliphatic alcohols (ALC), acetone mobile polar lipids (AMPL) and phospholipids (PL) concentrations and yields were highest in the Chu medium. Triglyceride (TAG) and sterol (ST) concentrations were highest in the LC Oligo medium. The results suggested that for cost effective cultivation, LC Oligo medium is the best choice among those studied, as it saved the cost of buying vitamins and EDTA associated with the other growth media, while at the same time resulted in the best growth performance and biomass production.

Physical And Chemical

Isolation and characterization of Chlorella vulgaris (green alga) and Anabaena variabilis (cyanobacterium) were made from natural and artificial water bodies of Dhaka University and Khulna, Bangladesh from March through December 2014 using modified Chu-10D medium to determine their potential as feedstock for biofuel production. Optimum growth measured as total chlorophyll and optical density under varying physical and chemical environments was determined. The optimum growth for C. vulgaris was obtained at pH 6.5 under light intensity of 110 μE m-2 s-1 and one and a half times the concentration of the Chu-10D. Compared to this, the optimum growth for A. variabilis was obtained at 7.0 pH, 90 μE m-2 s-1 light intensity and normal Chu 10D. Both organisms were grown at 25o C temperature. Aeration of medium showed a significant positive growth for both the isolates. Supplementation of medium with vitamin B1, B6, B7 and B12 would yield higher biomass of C. vulgaris as biofuel feedstock. Vitamins were not required for growing A. variabilis. Asiat. Soc.
