Abstract

Water pollution is an environmental problem, the waters are accompanied by organic matter, nutrients and trace amounts of metals. The physicochemical treatments allow partial removal of the organic load, however the costs are high, therefore it is advisable the use of other processes as the biologic. Contaminated rivers represent an interesting source of microorganisms capable of degrading different substrates, considering candidates for isolation and purification processes used in contaminated water. The strategy of bioremediation technologies is the use of different metabolic pathways and increased degradation of native processes to eliminate or reduced the contaminating substances. The isolates were monitored in medium with different substrates (carbohydrates, proteins and glycerol). Nineteen bacterial isolates from the three monitored water bodies were obtained, the percentage of capacity to assimilate strains with different carbohydrates varied depending on the compound, 100% of the strains degraded dextrose and sucrose, degraded 86% starch, 66% casein and none of the isolates showed hydrolysis of gelatin and lipase production. Results are in close relation to the place of done these bacteria were isolated; as different levels of contamination may influence the bacteria present characteristics to adapt to the use of a wide range of carbohydrates. Although the degradation of pollutants in nature is often the result of the activity of a microbial consortium rather than a single organism, the potential degrader consortium depends on the potential that microorganisms present individually in their interaction with specific pollutants, for this reason have isolated autochthonous capacity to remove organic matter is a pathway for future use.
