“…Moreover, microorganisms present in these sites could be selected by controlling the adequate environmental factors, such as pH, salinity and organic matter content (Al-Saleh et al 2009). Vieira et al (2007) selected different undefined mixed microbial consortia from petroleum pollutes sites, and evaluated their diesel biodegradation efficiencies. Nikakhtari et al (2009) also used indigenous mixed microbial consortia from polluted sites, whose degradation ability was compared with commercial and donated consortia.…”

Three microbial consortia were isolated from three polluted soils located at an oil refinery and acclimated to grow on diesel fuel as the sole carbon source. Batch experiments were then conducted with the three consortia to study the kinetics of diesel biodegradation. The effects of temperature (25, 30 and 35°C) and diesel concentration (0.5, 1 and 3 %) on the biodegradation of diesel were analysed. Several species were identified in the acclimated microbial consortia, and some of them appeared in more than one consortium. Thermal inhibition was observed at 35°C. In the rest of experiments, over 80 % of the substrate was degraded after 40 h of treatment. These results proved the good feasibility of using the polluted sites as sources of mixed consortia for hydrocarbon degradation. However, diesel degradation efficiencies and rates were very similar, suggesting that the acclimation process produced mixed consortia with very similar characteristics; in this context, origin of the soil sample was not a decisive factor. A simple Monod-type kinetic model was used to simulate the biodegradation process, and accurate results were obtained. The l max values were between 0.17 and 0.34 h -1 . The results of this study revealed that the consortia can function at high concentrations of hydrocarbons without any sign of growth inhibition, which is important for the design of bioreactors for wastewater treatment with high concentrations of fuel.

“…Inicialmente, foi utilizada a cultura mista denominada C1 empregada nos trabalhos de Vieira et al (2007de Vieira et al ( e 2010. Essa cultura foi isolada do solo de uma lagoa que recebe o efluente gerado na lavagem do pátio e dos caminhões de uma distribuidora de combustíveis situada na cidade de Uberlândia-MG. O lodo denominado de C2 foi gentilmente cedido pela Souza Cruz -Fábrica Uberlândia-MG da unidade de tratamento anaeróbio de efluentes.…”

RESUMO A intensiva busca por fontes alternativas de energia e processos sustentáveis visando a redução da poluição ambiental e o aquecimento global do planeta tem estimulado o mercado mundial de combustíveis limpos como o biodiesel, que representa uma alternativa renovável e ambientalmente segura aos combustíveis fósseis. Mas, decorrente deste aumento de produção as possibilidades de ocorrência de acidentes são grandes e consequentemente as contaminações do ambiente são crescentes. Os processos biológicos, envolvendo uma grande gama de microrganismos de fontes diferentes adaptadas podem se tornam uma alternativa interessante no tratamento de efluentes contaminados por biodiesel. Portanto, este trabalho avalia a potencialidade de microrganismos de fontes diferentes biodegradar o biodiesel como fonte de carbono. Foram testadas duas culturas, uma mista (C1) facultativa advinda de local contaminado por derivados de petróleo (óleo diesel e gasolina), e outra cultura (C2) advinda de lodo de sistema de tratamento anaeróbio de efluentes da indústria de produção de cigarros, ambas previamente adaptadas ao biodiesel em meio líquido. Cada uma das culturas apresentaram meios de cultivo (M1 para cultura mista e M2 para o lodo), previamente preparados e esterilizados e condições de processos diferenciados, em função dos microrganismos empregados. As variáveis de resposta foram pH e remoção de DQO. Dentro desta concepção, a cultura que apresentou maior capacidade em biodegradar o biodiesel foi a cultura C2 no tempo de 7 dias de processo. Estes resultados mostram que a fonte do tipo de cultura interfere na capacidade de remoção do contaminante e isto está associado a seu potencial metabólico. INTRODUÇÃOCom o crescimento da produção de biodiesel aumenta-se significativamente a probabilidade de derramamentos acidentais durante o processo, transporte e armazenagem, potencializando o risco de contaminação do ambiente (solo e água). Devido a isso, técnicas de tratamento de solo e água contaminado por hidrocarbonetos derivados do biodiesel têm sido alvo de inúmeros estudos e constituem um grande desafio para a comunidade científica que busca obter métodos eficazes, economicamente viáveis e compatíveis com os aspectos socioambientais atuais. Devido à complexidade e diversidade das contaminações, não há uma regra que determine o melhor tratamento a ser utilizado. Cada caso deve ser analisado individualmente, avaliando suas particularidades. Em geral, o sucesso da técnica empregada

“…This confirms the results of Shabir et al (2008) who showed that, generally, hydrocarbons in kerosene are not inhibitory to microbial activity and will biodegrade significantly, provided that sufficient amounts of essential nutrients are present. Moreover, Vieira et al (2007) demonstrated that n-alkane compounds are the most susceptible to microbial attack, followed by branched alkanes, aromatics of low molecular weight. The isolated strains belonged to the genera Bacillus, Staphylococcus and Pseudomonas; all are well known to biodegrade a large spectrum of hydrocarbons, and are frequently isolated from polluted sites; the predominance of one genus is related to environmental conditions such as pH and salinity (AL-Saleh et al, 2009).…”

“…In this study, all reservoirs contained, at least, one strain of Pseudomonas. Indeed, Pseudomonas strains have frequently been found in various sites polluted by petroleum and petroleum derivatives (AL-Saleh et al, 2009;Floodgate, 1984;Richard and Vogel, 1999;Vieira et al, 2007), suggesting that this genus, effectively, metabolizes hydrocarbon molecules and may dominate bacterial populations in media where petroleum pollution has occurred. Only five strains were isolated from diesel oil reservoir.…”

The petroleum reservoirs are commonly exposed to bacterial contamination. The proliferation of several bacterial species, could modify the product quality, change viscosity, help other sulfatereducing, iron reducing bacteria to grow, and accelerate reservoir biocorrosion. Thus, companies of storage and transport of petroleum frequently use biocides to prohibit bacterial proliferation. However, the use of the appropriate biocide, need an obvious knowledge of bacterial population harbouring the reservoir. Thus, in this study, we intended to isolate and identify the aerobic bacterial population existing in different reservoirs of petroleum derivatives in the refinery of Bizerte, Tunisia. The isolation and identification of these microorganisms may be of great interest in bioremediation of polluted sites. Besides, it could inform about hydrocarbon specificity of these microorganisms and therefore lead to the use of suitable biocides to clean these storage reservoirs. 25 different bacterial strains were isolated from water collected from reservoirs of crude oil, gasoline, diesel oil and kerosene. The different strains were identified using morphological and biochemical characterization, as well as sequencing of 16S rRNA. The systematic study of these strains showed that they belong to six different genera. The highest strain number was affiliated to the genera of Pseudomonas and Bacillus followed by genera of Staphylococcus, Enterobacter Comamonas and Paenibacillus. The results of this study are discussed in terms of the ecological significance of these microorganisms in relation with physicochemical conditions of reservoirs and hydrocarbon composition.
