“…Together with K. oxytoca, they also isolated Acinetobacter baumannii and Stenotrophomonas maltophilia. Used alone, K. oxytona was able to remove only 11% of the phenantrhere contaminant, whereas in a consortium, the three microorganisms degraded 80% PHE in 360 h. It is interesting to note that K. oxytoca is reported by Khalid et al (2009) and Kim et al (2009) as having the ability to degrade compounds like PHE and 4-nitroaniline which have cyclic closed carbon rings. In the present report, this microorganism was isolated in an enrichment process with a linear hydrocarbon molecule.…”

“…and Citrobacter freundii) that were able to grow on 4-nitroaniline from textile dye wastewater. This microorganism consortium was able to remove 100% of 4-nitroaniline in 72 h. Kim et al (2009) have isolated K. oxytoca from phenanthrene (PHE) which is a polycyclic aromatic hydrocarbon composed of three fused benzene rings. Together with K. oxytoca, they also isolated Acinetobacter baumannii and Stenotrophomonas maltophilia.…”

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.

“…Thus, the degradation of paracetamol could be performed by the single isolates, but is greatly stimulated by a synergistic interaction of the consortium obtained from the same paracetamol-degrading culture. In fact, microbial mixed cultures are generally considered to be potentially more efficient in the biodegradation of recalcitrant compounds (Kim et al 2009). A co-culture of three different bacterial species was shown to be necessary for complete fluorobenzene mineralization (Carvalho et al 2002).…”

Three bacterial strains utilizing paracetamol as the sole carbon, nitrogen, and energy source were isolated from a paracetamol-degrading aerobic aggregate, and assigned to species of the genera Stenotrophomonas and Pseudomonas. The Stenotrophomonas species have not included any known paracetamol degraders until now. In batch cultures, the organisms f1, f2, and fg-2 could perform complete degradation of paracetamol at concentrations of 400, 2,500, and 2,000 mg/L or below, respectively. A combination of three microbial strains resulted in significantly improved degradation and mineralization of paracetamol. The co-culture was able to use paracetamol up to concentrations of 4,000 mg/L, and mineralized 87.1 % of the added paracetamol at the initial of 2,000 mg/L. Two key metabolites of the biodegradation pathway of paracetamol, 4-aminophenol, and hydroquinone were detected. Paracetamol was degraded predominantly via 4-aminophenol to hydroquinone with subsequent ring fission, suggesting new pathways for paracetamol-degrading bacteria. The degradation of paracetamol could thus be performed by the single isolates, but is stimulated by a synergistic interaction of the three-member consortium, suggesting a possible complementary interaction among the various isolates. The exact roles of each of the strains in the consortium need to be further elucidated.
