Production of algal biomass

Abstract

Among renewable resources, algae have proven to be an attractive feedstock for rapid generation of carbohydrates and lipids by utilizing its photosynthetic ability to present itself as an alternative energy source. Different species of algae, being environmental friendly, are strong candidates for generation of biomass, and are used in production of biogas and biofuel. Continuous efforts are being made to increase its large-scale production by application of specific methods chosen on the basis of desired downstream processing and final application of algal biomass. Biomass production is dependent upon cultivation methods for harvesting, followed by quantification of biochemical composition of biomass. Harvesting of algal mass is a major concern playing crucial role in determination of process economy required for further applications including biofuel production. Although algal biomass appears to be an efficient substrate for biofuel production, the progress is hindered by ammonia inhibition and ion toxicity. Further research is needed to replace the continuously depleting energy sources with renewable, eco-friendly sources.
