Cultivation of Microalgae Chlorella vulgaris in Open Reactor for Bioethanol Production

Microalgae have a high growth rate, CO2 absorption capacity, and content of chlorophyll, proteins, vitamins, mineral salts, carbohydrates, antioxidant substances, fatty acids. In recent years, Chlorella vulgaris has been widely used as feedstock for producing third-generation biofuels, such bioethanol. Thus, this work aims to develop strategy increase the production scale microalgae grown in distilled reused water, supplemented with modified BG-11 medium, use biomass The total cultivation 72 L presented concentration 0.415 g·L−1·d−1, 61.32 g final biomass. To improve carbohydrate extraction, was pre-treated sulfuric acid at different concentrations (1.5% 3% v/v). hydrolyzed solution YPD (yeast extract peptone dextrose) medium inoculated Saccharomyces cerevisae yeast, initiating fermentation. each sample, Brix degree, cell concentration, reducing sugar alcohol were analyzed. sample 1.5% v/v one that best result, after distillation 68 °GL (Gay-Lussac). It appears scale-up, potential biofuel.
