“…Therefore, our findings are in agreement with several publications that report that microorganism consortium is capable of transforming the environment where they are placed and/or found (Binks et al, 1996;Kanaly et al, 2000;Carvalho et al, 2002;Haruta et al, 2002;Li and Gu, 2007;Itah et al, 2009;Khalid et al, 2009;Kim et al, 2009;Fang et al, 2010;Hua et al, 2010;Radwan et al, 2010;Rajasekar et al, 2010;Jandandhu and Fulekar, 2011;Sakultantimetha et al, 2011;Waranusantigul et al, 2011;Chanthamalee and Luepromchai, 2012;Juárez-Ramirez et al, 2012;Turgay et al, 2012;Shin et al, 2012;Simarro et al, 2013).…”

“…It has been reported that it can also accumulate heavy metal (Fang et al, 2010;Kanaly et al, 2000;Turgay et al, 2012;Rajasekar et al, 2010), grow on explosives such as pentaerythritol tetranitrate (PETN) and 2,4,6-trinitrotoluene (TNT) as sole nitrogen source (Binks et al, 1996;French et al, 1998) and it can decontaminate water from herbicides (Chena et al, 2009;Sakultantimetha et al, 2001;Ngigi et al, 2012). Also, this microorganism has been isolated from materials contaminated with crude oil.…”

“…Sphingobacterium is known by its ability to degrade pollutants such as pesticides, textile dyes and petroleum and its derivatives (Kanaly et al, 2000;Carvalho et al, 2002;Macbeth et al, 2004;Fang et al, 2010;Nagata et al, 2010;Tamboli et al, 2010;Janbandhu and Fuleka, 2011). Polycyclic aromatic hydrocarbons (PHA) can be found in oil, coal and tar deposits, and they are also produced as byproducts of fuel burning.…”

As the world population increases, the need for energy resources increases and for decades, petroleum has sustained this demand. Oil spill during petroleum extraction and processing has a negative impact on the environment. Methods that can decrease the impact of xenobiotic compounds on the environment have been developed. Among many bioremediation methods described, microbial remediation is of great importance. Our previous work demonstrated that Organic Waste Composting Unit (OWCU) located at the São Paulo Zoo Foundation (FPZSP) had a great diversity of microorganism. In the present work, we viewed this environment searching for xenobiotic degrading microorganisms by sampling the composting at various stages of the process with the aim of isolating the bacteria that would break down n-hexadecane, a model compound for hydrocarbon degradation. Two bacterial collections were assembled and tested in a 96-well plate model using n-hexadecane as a sole carbon source. Among the 418 isolates screened, eight were selected based on their ability to assimilate nhexadecane. Molecular identification revealed their genus and species which are associated with xenobiotic degradation activities in different microbial consortia. However, these microorganisms have not being isolated from the same transforming process. Future studies with these isolates may shed light on the bacteria hydrocarbon degradation mechanism.

In this study, the dechlorination efficiency was nearly 100% within 102 h which was much higher than the mentions above.…”

a b s t r a c tA novel non-dsrAB (without dissimilatory sulfite reductase genes) sulfate-reducing bacterium (SRB) Clostridium sp. BXM was isolated from a paddy soil. Incubation experiments were then performed to investigate the formation of reduced sulfur compounds (RSC) by Clostridium sp. BXM, and RSC-induced dechlorination of p,p 0 -DDT in culture medium and soil solution. The RSCs produced were 5.8 mM and 4.5 mM in 28 mM sulfate amended medium and soil solution respectively after 28-day cultivation. The p,p 0 -DDT dechlorination ratios were 74% and 45.8% for 5.8 mM and 4.5 mM RSCs respectively at 6 h. The metabolites of p,p 0 -DDT found in the two reaction systems were identified as p,p 0 -DDD and p,p 0 -DDE. The dechlorination pathways of p,p 0 -DDT to p,p 0 -DDD and p,p 0 -DDE were proposed, based on mass balance and dechlorination time-courses. The results indicated that RSC-induced natural dechlorination may play an important role in the fate of organochlorines.Crown

“…Investigations have demonstrated that bioremediation is a feasible solution for treating organic contaminants including PCB, PCNB, DDT, DDE and DDD (Fang et al, 2010;Li and Yang, 2013;Liu et al, 2010;Wang et al, 2016a). High efficiency degradation strains are a key factor for bioremediation of organic pollutants.…”
