Abstract:
With the potential of being deconstructed to produce biofuels and platform chemicals, algae and water hyacinth has been boasted to be an attractive renewable and sustainable resource. For hydrolysis of biomass (algae and water hyacinth) two different chemicals with varying concentration and time were tried using an autoclave. For algal biomass hydrolysis, 5% acetic acid for 60 minutes was found to be the best and for water hyacinth, 2% nitric acid for 60 min treatment was found optimum. C:N:P ratio was higher in the hydrolysate prepared from water hyacinth (60:10:1) than algae (23:1:5). The hydrolysates containing high amount of solubilized carbohydrate and nutrients were used to grow Chlorella sorokiniana (isolated from municipal wastewater treatment plant grow optimally at pH 9). Different light intensities and light-dark cycle were used as the parameters to optimize the lipid and carbohydrate accumulation. For the enhancement of lipid and biomass production of algae, amount of external sugar and inorganic carbon addition were varied to find the optimal values of those parameters. Lipid analysis was carried out after transesterification and saturated and unsaturated fatty acids were detected in the Chlorella sorokiniana.
