| Abstrak/Abstract |
Euglena is a microalga with the potential to be used as a renewable energy source. The biofuel-making potential is present in Euglenaspecies biomass's proteins, lipids, and carbohydrates. Therefore, optimizing microalgal growth under various physiological conditions is crucial to obtainingmore biomass. In this study, Euglenasp. was cultivatedon medium Cramer-Myers (CM) and subjected to various temperatures and acidities. Euglenasp. cultures were optimized at different pH levels, including 2.5, 3.5, and 5.5, and at 29 and 32°C. Then, treatments were evaluated on the culture's pace of cell development, total biomass, and amount of carbohydrates, protein, and lipids. Based on the results, Euglenasp. at pH 5.5 and 29°C had the optimal growth rate, biomass, carbohydrate, protein, and fat content compared to the other treatments. In a pH 5.5 at 29°C, the average biomass was 0.382±0.173 g/L, and the resulting concentrations of protein, carbohydrates, and lipids of 0.288±0.12, 0.201±0.052, and 0.182±0.083 g/L, respectively. |
