Comparación de eficiencia entre Pseudomonas aeruginosa y Pseudomonas putida, y su masificación para la remediación de hidrocarburos totales de petróleo en los pasivos ambientales de AQ-LAB en Puerto Francisco de Orellana.

Abstract

This research is intented to evaluate the efficiency of total pretroleum hydrocarbon degradation TPHs, through the Pseudomona aerogynose and the Pseudomona putida ad their masification for the environmental liabilities remediation from the Landfarming technique applied in the AqLab from Puerto Francisco de Orellana. Throughout this study laboratory analysis, the efficiency of 12 experimental cases were tested by codifying two of them like the study aim as 1 and 2, the other ten cases were divided by two as 1a, 1b, 1c, 1d and 1e for the Pseudomona aerogynosa ATCC 15442TM* treatment, and 2a, 2b, 2c, 2d, 2e for the Pseudomona putida ATCC 31483TM* treatment, in regarding the pH, temperature and wetness parameters. Which results. Which results accounts for an efficiency of 89,8% in the 1a and 2e experimental cases whereas it increases to 94% in the 2c experimental case. The TPHs degradation was carried out though Pseudomona putida masification which were inoculated into the soil sample stimulated by applying the Landfarming technique that gave a degradation of 123630,66 mg/Kg – 2400 mg/Kg considering the final disposition in regarding the limit parameters stated on the Chart 6, concerning with Environmental Regulation on Ecuadorian Hydrocarbon Operations and Agriculture (RAOHE) of Ecuadorian Legislation, from which the TPHs degradation rate accounted for 98,24%. Therefore, we can conclude that the Pseudomona putida is more efficient that Pseudomona aerogynose but comparing them whit ANOVA as an independent factor, the efficiency of both treatments is statistically equal. Thus, for further researches is advisable to make a comparison of treatments from other different species.
