“…In fact, biodegradation of pollutants relies on integrated activities of enzymes, cells, and microorganisms communities, whose regulation and kinetics are highly specific, though also greatly variable in space and time. Since biodegradation depends on environmental factors, including nutrients levels, availability of substrates, predation, population density, contaminant concentration, pre-exposure, and bioavailability [7], active microbial communities must often be either sustained with either metabolic substrates or specifically potent external communities.…”

Background: Bioremediation is a low-cost technology, whose efficacy is often enhanced with preliminary mild physical-chemical remediation methods. A further advantage of bioremediation resides in its eco-compatibility and, thus, sustainability. Two autochthonous microbial strains, Methylobacterium populi VP2 and Aspergillus sydowii VP4, were isolated from a soil of a highly contaminated industrial site and used to degrade the aqueous extract of contaminants (AEC) obtained from the same polluted soil. Results:The AEC incubation with both strains produced a significant removal of most organic pollutants, although the degradation capacity decreased with increasing AEC concentration in the minimal selective liquid medium (MSML) of the experiments. At 30 % of AEC, M. populi VP2 determined the removal of most pollutants and the appearance of new products due to oxidation and enzymatic degradation. Incubation of A. sydowii VP4 at the same AEC concentration in MSML removed the same pollutants but also the derived degradation products. Our results showed that the strains isolated from a highly contaminated soil maintained the capacity to use organic contaminants as metabolic carbon in aqueous extracts from the same soil. The greater biodegradation efficiency of the fungal strain in comparison to M. populi VP2 may be caused by a modification of the A. sydowii VP4 cell surface that increases cell permeability to hydrophobic compounds and thus enhances the extent of pollutants degradation. Conclusions:This work indicates that two specific strains, M. populi VP2 and A. sydowii VP4, isolated from the soil of a highly contaminated site are not only useful in the treatment of leaching polluted waters but may also be used in bioaugmentation practices during remediation of contaminated soils.

Phenol represents a huge problem in industrial wastewater effluents and needs to be removed due to its toxic and carcinogenic nature. The removal of phenol from the wastewater is often both expensive and time consuming; there is therefore a requirement for a more effective, sustainable solution for the removal of phenol from wastewaters.Bioaugmentation or the addition of phenol degrading microorganisms to contaminated effluents is one such sustainable approach being considered. Here, we describe how bioaugmentation has been applied for the biological treatment of phenol in industrial wastewaters.

“…Therefore, treatment of phenol effluents is critical to maintaining both human and wildlife environments. Several methods to remove these chemicals from environmental matrices currently exist including activated carbon adsorption, electrochemical, ozonization, and biological and chemical procedures (Dąbrowski et al 2005;Mahmoud and Ahmed 2009;Deborde et al 2008;Santos et al 2009;Lin et al 2009). Among these methods, biological degradation is generally preferred because of its lower costs, environmental friendliness, practical and economic viability as it allows forming less hazardous byproducts and realizing complete mineralization of phenol (Chung et al 2003;Nuhoglu and Yalcin 2005).…”

An aerobic microorganism with an ability to utilize phenol as sole carbon and energy source was isolated from phenol-contaminated wastewater samples. The isolate was identified as Bacillus amyloliquefaciens strain WJDB-1 based on morphological, physiological, and biochemical characteristics, and 16S rDNA sequence analysis. Strain WJDB-1 immobilized in alginate-chitosan-alginate (ACA) microcapsules could degrade 200 mg/l phenol completely within 36 h. The concentration of phenol was determined using differential pulse voltammetry (DPV) at glassy carbon electrode (GCE) with a linear relationship between peak current and phenol concentration ranging from 2.0 to 20.0 mg/l. Cells immobilized in ACA microcapsules were found to be superior to the free suspended ones in terms of improving the tolerance to the environmental loadings. The optimal conditions to prepare microcapsules for achieving higher phenol degradation rate were investigated by changing the concentrations of sodium alginate, calcium chloride, and chitosan. Furthermore, the efficiency of phenol degradation was optimized by adjusting various processing parameters, such as the number of microcapsules, pH value, temperature, and the initial concentration of phenol. This microorganism has the potential for the efficient treatment of organic pollutants in wastewater.
