Variation of sterols and fatty acids as an adaptive response to changes in temperature, salinity and pH of a marine fungus Epicoccum nigrum isolated from the Patagonian Fjords

We isolated and identified a marine fungus strain from samples of sediments obtained from a sector of the Patagonian fjords. The LQRA39-P strain was identified as Epicoccum nigrum using microscopy techniques and corroborated using molecular techniques. We expect to prove that metabolic variation res...
