“…It was also reported previously that the biodegradation of Nap, Ant, Phe and Pyr fitted for the first-order kinetics [24][25][26], met the result in this study. The reaction rate constant Àb stands for speed of the chemical reaction, suggesting a lower stability of the compounds with a higher b value.…”

“…The higher relative abundance of Actinobacteria in PAH amended soil appears to have been driven largely by an increase in the abundance of a single unclassified OTU from the family Micrococcaceae (OTU 1). Members of the Micrococcaceae such as Arthrobacter phenanthrneivorans (Kallimanis et al, 2009 ) and Arthrobacter oxydans (Thion et al, 2013 ) have been associated with PAH degradation, both in pure culture and in the environment (Aryal and Kyriakides-Liakopoulou, 2013 ). Although considerably less relatively abundant than the Micrococcaceae , unclassified Microbacteriaceae were also significantly more abundant in phenanthrene-amended soil, and this group has also been associated with PAH degradation in soil (Jacques et al, 2008 ; Jie et al, 2011 ).…”

Bioremediation offers a sustainable approach for removal of polycyclic aromatic hydrocarbons (PAHs) from the environment; however, information regarding the microbial communities involved remains limited. In this study, microbial community dynamics and the abundance of the key gene (PAH-RHDα) encoding a ring hydroxylating dioxygenase involved in PAH degradation were examined during degradation of phenanthrene in a podzolic soil from the site of a former timber treatment facility. The 10,000-fold greater abundance of this gene associated with Gram-positive bacteria found in phenanthrene-amended soil compared to unamended soil indicated the likely role of Gram-positive bacteria in PAH degradation. In contrast, the abundance of the Gram-negative PAHs-RHDα gene was very low throughout the experiment. While phenanthrene induced increases in the abundance of a small number of OTUs from the Actinomycetales and Sphingomonadale, most of the remainder of the community remained stable. A single unclassified OTU from the Micrococcaceae family increased ~20-fold in relative abundance, reaching 32% of the total sequences in amended microcosms on day 7 of the experiment. The relative abundance of this same OTU increased 4.5-fold in unamended soils, and a similar pattern was observed for the second most abundant PAH-responsive OTU, classified into the Sphingomonas genus. Furthermore, the relative abundance of both of these OTUs decreased substantially between days 7 and 17 in the phenanthrene-amended and control microcosms. This suggests that their opportunistic phenotype, in addition to likely PAH-degrading ability, was determinant in the vigorous growth of dominant PAH-responsive OTUs following phenanthrene amendment. This study provides new information on the temporal response of soil microbial communities to the presence and degradation of a significant environmental pollutant, and as such has the potential to inform the design of PAH bioremediation protocols.

“…Surfactants are amphiphilic molecules that can enhance the apparent solubility of PAHs by forming micelles when present at concentration above the critical micelle concentration (CMC). Some researchers have reported enhancement in biodegradation of PAHs in presence of surfactants (Prak and Pritchard, 2002;Zheng and Obbard, 2002;Aryal and Liakopoulou-Kyriakides, 2013;Chen et al, 2013). However, sometimes no beneficial effect/detrimental effect have been observed (Laha and Luthy, 1991;Margesin and Schinner, 1999;Mesbaiah et al, 2015).…”
