        abstract = {Algal biomass-based bioethanol offers a viable path towards environmentally responsible and sustainable biofuel production. Algal species, especially microalgae, are perfect third-generation biofuel feed stocks because of their high carbohydrate content, quick growth rates, and lack of competition with food crops. The process of turning algal biomass into bioethanol by enzymatic saccharification and microbial fermentation is examined in this work. In order to break down cell walls and increase enzyme accessibility, the pre-treatment procedure included alkaline treatment and acid hydrolysis using diluted sulphuric acid. Cellulase was used in enzymatic hydrolysis to convert complicated polysaccharides into fermentable sugars, which were then fermented by Saccharomyces cerevisiae.The amounts of sugar and ethanol were measured analytically using techniques like the DNS test and potassium dichromate test, respectively. The ethanol content increased steadily, reaching a peak of 0.367 mg/ml after 27 hours, according to the results. The viability of using algal biomass as a substrate for the generation of ethanol is confirmed by this investigation. High processing costs and variations in algal composition, however, continue to be obstacles to process expansion. Process viability can be increased by further research on choosing resilient algae strains, enhancing enzymatic efficiency, and optimising fermentation conditions. According to the research, bioethanol derived from algae has the potential to be a clean substitute for fossil fuels, supporting the objectives of the circular bio economy and sustainable energy.},
