Levaduras oleaginosas aisladas de dos lagos de la Universidad del Valle
(Universidad Santiago de Cali, 2020) Benavides León, Tatiana Andrea; Ramírez Castrillón, Mauricio; Osorio Cadavid, Esteban
In Colombia, the study of the biotechnological, microremediative, and industrial potential of the yeast community has been limited, since most of the research has only focused on species of clinical interest. Some yeasts are oleaginous by accumulating lipids between 20 to 70% of their weight, showing great potential in the biofuel and food industry. The objective of this study was to evaluate and characterize the lipid composition of yeasts previously isolated from two lakes of the Universidad del Valle. This study gravimetrically evaluated 25 yeast strains, where 52% showed oleaginous capacity with a range between 0.045 g/L and 0.598 g/L. The selected strains with lipid accumulation potential were identified at the molecular level. The Aureobasidium sp. LC112 is suggested as promising due to its high biomass production, lipid yield of 38.2% and a lipid profile with 50% saturated fatty acids, 25% monounsaturated and 25% polyunsaturated. Therefore, this strain has great potential in the biofuel, pharmaceutical, food and cosmetic industries
