“…These findings were similar to the study of Goudar and Strevett 18 who degraded BTEX using a respirometry. In this study biodegradation rate increased in the order of B<X<E<T, this finding slightly varied from You et al 19 who showed degradation by Psuedomonas putida YNS1 increased in the order of X<B<E<T and stated that this difference may be due to strains that can degrade BTEX in different pathway. Maximum growth yield of the isolate MVSV3 was found to be 2.6 g/L.…”

Monoaromatics, such as benzene, toluene, ethylbenzene and xylene (BTEX), are simple aromatic compound that are highly toxic due to their high solubility nature. Many chemical and physical methods for their degradation and breakup into nontoxic products are available, but still use of microorganism is preferred over these processes. In this present study Bacillus pumilus MVSV3 (Accession number JN089707), a less explored bacteria in the field of BTEX degradation, isolated from petroleum contaminated soil is utilized for BTEX degradation. At optimized conditions the isolate degraded 150 mg/L of BTEX completely within 48 h. GC-MS analysis revealed that the microorganism produces catechol and muconic acid during degradation indicating an ortho pathway of degradation. Enzyme assays were carried out to identify and characterize catechol 1, 2-dioxygenase (C12D

“…Removal of phenol from contaminated soil and industrial effluents by bioremediation techniques can be achieved through aerobic biodegradation, by microorganisms utilizing this toxic aromatic compound as a sole source of carbon and energy. Pseudomonas putida has been the most extensively studied bacterium for aromatic compound biodegradation (Morasch et al 2002; Reardon et al 2002; Wang et al 2008; You et al 2013). Alcaligenes eutrophus (NRRL B 75940) (Hill et al 1996), Bacillus stearothermophilus BR219 (Gurujeyalakshmi and Oriel 1989), and some bacterial strains belonging to Acinetobacter spp., Citrobacter spp., and Shigella spp.…”

In this study, the potential of selected psychrotolerant yeast strains for phenol biodegradation was studied. From 39 strains isolated from soil and water samples from Rucianka peat bog, three psychrotolerant yeast strains, A011, B021, and L012, showed the ability to degrade phenol. The result shows that all three yeast strains could degrade phenol at 500 and 750 mg l−1 concentration, whereas strains A011 and L012 could degrade phenol at 1000 mg l−1 concentration. The time needed for degradation of each phenol concentration was no longer than 2 days. Strains A011, B021, and L012 were identified based on 26S rDNA and ITS sequence analysis as belonging to species Candida subhashii, Candida oregonensis, and Schizoblastosporion starkeyi-henricii, respectively.

“…For instance, P. aeruginosa can grow in the presence of a variety of aliphatic and aromatic compounds such as lactate (Gao et aromatic fl uoranthene, phenanthrene (Zhang et al 2011), hexadecane, benzene, toluene (S Mukherjee et al 2010), paracetamol (Hu et al 2013), and 4-chlorobenzoate (Hoskeri et al 2011). Similar wide range of assimilation of substrates has been reported with other species of the same genus, such as Pseudomanas putida with biodegradation of aromatic compounds (Diaz et al 2008, Ebrahimi and Plettner 2013, El-Naas et al 2009, Fernandez et al 2012, Hwang et al 2009, Li et al 2011, Q Lin and Jianlong 2010, Phale et al 2013, Takeo et al 2006, You et al 2013) and alkane derivatives (Dunn et al 2005, Johnson and Hyman 2006, Smith and Hyman 2004. In line with previous reports, Pseudomonas aeruginosa strain N7B1 had a wide range of substrate specifi city, thus is an important bacterium that could be used in bioremediation strategies.…”

Bioremediation is based on microorganisms able to use pollutants either as a source of carbon or in co-metabolism, and is a promising strategy in cleaning the environment. Using soil contaminated with petroleum products from an industrial area in Saudi Arabia (Jubail), and after enrichment with the polycyclic aromatic hydrocarbon (PAH) naphthalene, a Methylobacterium radiotolerans strain (N7A0) was isolated that can grow in the presence of naphthalene as the sole source of carbon. M. radiotolerans is known to be resistant to gamma radiation, and this is the fi rst documented report of a strain of this bacterium using a PAH as the sole source of carbon. The commonly reported Pseudomonas aeruginosa (strain N7B1) that biodegrades naphthalene was also identifi ed, and gas chromatography analyses have shown that the biodegradation of naphthalene by M. radiotolerans and P. aeruginosa did follow both the salicylate and phthalate pathways.
