Microbial consortia are natural associations adopted by microbial communities, acting together and generating complex systems that generate benefits for them. The main objective of the research was to obtain an oil biodegrading microbial consortium from the thermal waters of Contamana. The sample selection criterion was the temperature of the surface waters, which were higher than 40°C. Microbial consortia were cultured in Erlenmeyer flasks with BH culture medium and crude oil and evaluated for 30 days. The microbial consortia were observed with gram staining by fluorescence microscopy, the growth profile and crude oil degradation were quantified by spectrophotometry. The results show that the most common bacterial forms present in the samples are cocci and Coccobacillus, both gram positive and gram negative. The microbial growth profile was gradual, obtaining values greater than 0.070 nm. of absorbance, compared to the control group that maintained lower values. The estimation of oil degradation through the quantification of total polyphenols, showed results that fluctuated between 40.20 and 13.20 mg/L. In conclusion, the results indicate that microbial consortia from hot springs have the ability to degrade crude oil.
