Abstract:
Biofuels as liquid and gaseous fuels are derived from renewable sources. Algae are one of the most common source ofbiofuel. The aim of present study was to identify, characterize, and to select polysaccharide-rich microalgae from indigenous resources and to produce bioethanol in a photobioreactor. All algal samples were identified through microscopic examination. For bioethanol synthesis, the sample with highest concentration of carbohydrates, glucose, and reducing sugar were selected. Experiments were conducted to investigate the influence of various circumstances that were regulated for algal development in current study. Three methods (biological, physical and chemical) were used for pretreatment of algal biomass and biological method was chosen because of higher sugar production. For biological conversion, amylolytic enzymes from microbial sources were used to hydrolyze microalgae to produce large quantities of sugars. In this investigation, out of four algal samples collected, one algal specie was identified based on highest concentration of polysaccharides, glucose, and reducing sugar for further studyof bioethanol production. A comparative analysis of flask and reactor experiment was carried out todetermine the a mount of ethanol produced. It was concluded that amount of ethanol produced by algal biomass obtained from a bioreactor was higher as compared to flask.
