Abstract. The commercialization of biodieselldiesel blends on the market can cause environmental damages due to spills. This study aims to investigate the effectiveness of Pseudomonas putida as oil-biodegradable agent in soil contaminated with biodieseVdiesel blend (B20). The eflkctiveness on bioremediation have been conducted by examined several physico-chemical tests on biodieselldiesel-contaminated soil before and after seeding of P. putida. The spillage stimulation of B20 was conducted at laboratory scale for 24 days of incubation time. The results show that the bioremediation treatment able to remove up to 82%, 77%, 1676, and 10% of nitrogen, phosphate, sulfate and total organic carbon, respectively. The pH of soil sample was changed from pH 7.45 (Day 0) to 7.25 (Day 24) after the treatment. Meanwhile, the moisture content in the sample has increased from 44.11% (Day 0) to 50.35% (Day 24). All of these results show the good indication of quality improvement of polluted soil after treated with P. putida. It is apparent from the acquired results that the application of P. putih is suitable as effective microorganism and potentially exploits as useful oil-soil biodegradable agent in polluted soil.

Abstract:The aim of this study was to isolate, characterize, and evaluate the potential of petroleum hydrocarbon (PHC)-degrading bacterial strains from oil-contaminated soil in the Meerut region. Among 59 oil-degrading bacterial cultures isolated from the oil-contaminated soil samples, 1 Bacillus species, 2 species of Pseudomonas, and 1 species of Micrococcus, identified on the basis of biochemical and 16s rDNA sequencing, were found to have the ability to utilize PHCs such as benzene, diesel, toluene, anthracene, and naphthalene. These strains were selected for further study to measure the quantitative determination of PHC metabolization. Along with these selected strains, a mixed bacterial consortium was formulated and used for PHC degradation. Among the individual strains, Pseudomonas sp. APHP9 performed better than the other bacterial isolates. Maximum biodegradation of benzene and toluene was done by the bacterial consortium. The mean growth rate constant (K) of soil isolates also increased with a successive increase in PHC concentration. Moreover, Bacillus sp. APHP6, Pseudomonas sp. APHP9, Pseudomonas sp. APBP1, Micrococcus sp. APIO4, and the consortium resulted in a 54.8%, 60.2%, 40.9%, 32.5%, and 66.2% decrease in benzene concentration and a 61.2%, 68.4%, 53.7%, 39.3%, and 75.4% decrease in diesel concentration, respectively, after 6 days of incubation as estimated by HPLC analysis.

“…Esto demuestra que el biodiesel acelera la biodegradación del diesel por efecto del cometabolismo (Demirbas, 2008;Lisiecki et al, 2014;Mariano, et. al, 2008;Pasqualino et al, 2006;Yassine, Wu, Suidan & Venosa, 2013;Zhang et al, 1998).…”

“…En las transformaciones cometabólicas, los microorganismos utilizan un segundo sustrato de elevada biodegradabilidad (en este caso el biodiesel) como fuente de carbono y energía para degradar el primer sustrato (en este caso el diesel) (Alexander, 1994;Mariano et al, 2008;Pasqualino et al, 2006;Zhang et al, 1998). De este modo, el cometabolismo puede ser empleado en la eliminación de sustratos resistentes como el petróleo crudo.…”

Resumen: El biodiesel es un combustible basado en ésteres metílicos de ácidos grasos con numerosas ventajas ambientales. Una de las más importantes es su elevada biodegradabilidad y su habilidad para disolver el petróleo crudo. En este estudio, se prepararon mezclas de petróleo crudo pesado y biodiesel y se midieron las densidades y viscosidades de dichas mezclas con el fin de evaluar la facilidad de recolección de las mismas en una zona afectada por un derrame. Se encontró que la densidad de todas las muestras estaba por debajo de la densidad del agua de mar, lo que indica que estas flotarán en la superficie. La viscosidad de las mezclas fue inferior varios órdenes de magnitud con respecto a la viscosidad del petróleo crudo pesado; esto indica la posibilidad de bombear fácilmente las mismas. Adicionalmente, se estudió la biodegradabilidad de las mezclas mediante el método de evolución de CO2. En todos los casos, la biodegradabilidad se incrementó con la adición del biodiesel y mostró la presencia de efectos sinérgicos debidos a cometabolismo. La mezcla, que contenía 50 % de petróleo crudo, demostró el mayor efecto sinérgico. Finalmente, se plantearon diversas soluciones para el tratamiento de aguas y suelos afectados por un derrame de petróleo crudo pesado. Palabras clave: Biodegradación, biodiesel, cometabolismo, derrame de petróleo.Abstract: Fatty acid methyl esters based fuel, known as biodiesel, is a clean renewable fuel with many environmental advantages. One of the most important is its high biodegradability and the ability to dissolve crude oil. In this study, we prepared mixtures of heavy crude oil and biodiesel and measured the density and viscosity in order to evaluate the possibility of collecting them from an affected area. The density of all the mixtures was below the density of sea water and the viscosity was several orders of magnitude lower than the viscosity of the pure crude oil. We also studied the biodegradability of the mixtures using the CO2 evolution test. In all the cases, the biodegradability was increased by the addition of biodiesel, showing that synergic effects occur by means of cometabolism. The mixture with 50 % fuel oil had the highest synergic effect. Several solutions are proposed for treating soils and water affected by an oil spill.
