Aislamiento e identificación de bacterias y levaduras resistentes a petróleo

Abstract

Different microorganisms were isolated from various rivers of the Huasteca Potosina, in Mexico that grow in the presence of petroleum as the sole carbon source. The activity of alcohol oxidase was determined by a colorimetric method. The most common bacteria present in the samples were Pseudomonas aeruginosa (50%) and only one type of yeast was found, Candida albicans (6.25%). Furthermore, they show good activity of alcohol oxidase in the cytosolic fraction with different substrates. It was concluded that this microorganisms could be used for decontamination of aquatic habitats polluted with petroleum.
