Bacterial Colonie Characterization from a Perforation Waste and Isolation from a Bacterial Consortium with Hydrocarbonclastyc Capacity

Microorganisms performance is of great importance in areas as the production of food, the medicine and the agriculture. In environmental area, bioremediation method is the most recommended in the recovery of soils impressed with petroleum hydrocarbons, due to its effi ciency and relative low cost. Also the potential utility of c ertain microorganisms is of interest for the petroleum industry to better recovery of perforatio n waste, thanks to the synthesis of biosurfactantes that in a ddition possess application in areas as medicine, food, cleanlines s, construction and the environmental one, among others. Bacterial colonies were isolated from a base oil perforation waste and characterized micro-macromorphologicall. Different enzymatical responses were studied. Colonies with hydrocarbonclastyc, lipolytic, beta hemolytic, ureasic, and proteolytic activity and producing of gas were found, but no colonies sulfate - reducers. A degradator culture was conformed and submit to test of effi ciency in the degradation of gasoil diesel. Aerobic mesophyles were quantified and to the concentration oil and grease diminished in 73, 7 % in 20 days. Bacterial consortium demonstrated to have potential for the recovery of soils contaminated with hydrocarbons of the oil.
