Abstract
The protection of the alloys of deep pipelines in the oil industry and similar coated with derivatives of aliphatic and aromatic hydrocarbons such as asphalt, tar and polyethylene are necessary to prevent damage to the different types of alloy in the pipes that are established in liquid environments such as water, or solid environments such as soil under abiotic and biotic conditions that cause corrosion and considerable economic losses in the restoration of fuel and water conduction systems: such as temperature, pH, concentrations of mineral salts, oxygenation level, etc. in which aerobic heterotrophic microbial activity. Therefore, the objectives of this work were i) to analyze the resistance to biodegradation of asphalt, tar and polyethylene tapes in the soil ii) to analyze the capacity of soil microorganisms to use these tapes as a source of carbon and energy iii) to identify the biochemistry of the microorganisms that attack these coatings. To this end, asphalt, tar, and polyethylene tapes were introduced into non-sterile soil to analyze what types of microorganisms use as a source of carbon and energy to biodegrade its destruction leading to corrosion. The microorganisms responsible for this biodegradation were then identified. The results show that a wide variety of microorganisms exist in the soil that biodegrade these tapes, utilizing them as a source of carbon and energy. These results support the need for chemical modifications to increase resistance to biodegradation and prevent damage to thousands of kilometers of deep-water pipelines used for various important human-industrial activities.
