dc.description.abstractWE 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 RESPONSES ALLOW UBIQUITOUS FUNGI TO DEVELOP IN MARINE, FRESHWATER, AND TERRESTRIAL ENVIRONMENTS. WE ANALYZED VARIATIONS IN THE CONTENT OF FATTY ACIDS AND STEROLS, IN A BATTERY OF CULTURE MEDIA AT DIFFERENT TEMPERATURES, SALINITY AND PH. THE CONTENT OF FATTY ACIDS AND STEROLS WAS ANALYSED USING GAS CHROMATOGRAPHY COUPLED TO MASS CHROMATOGRAPHY (GC-MS). CHANGES IN TEMPERATURE SHOWED NO SIGNIFICANT CHANGES IN THE FATTY ACID CONTENT; NEVERTHELESS, STEROL CONTENT WAS SIGNIFICANTLY AFFECTED BY THIS FACTOR AT JUST PH 4, INCREASING DIVERSITY OF STEROLS IN FRESHWATER AT 25°C. SALINITY GENERATED CHANGES IN THE LIPID COMPOSITION (I.E., C16:0; C16:1; C18:2 AND C18:3). AS FOR PH, THIS FACTOR HAS A SIGNIFICANT EFFECT ON THE COMPOSITION OF FATTY ACIDS AND STEROLS. WE DEMONSTRATE THAT E. NIGRUM IS CAPABLE OF CHANGING ITS COMPOSITION OF STEROLS AND FATTY ACIDS AS AN ADAPTIVE RESPONSE THAT MAY ENABLE CO-INHABITING MARINE AND TERRESTRIAL SUBSTRATES.
