In several cases, proteomic surveys were also employed to examine the catabolic pathways associated with biodegradation of organic pollutants (Loh and Cao 2008; Cao and Loh 2008; Kim et al. 2006; Verhoef et al. 2010; Yun et al. 2011).
Next to the proteomic and genomic based pathogen differentiation is a differentiation by metabolic profiling, as metabolism of microorganisms is associated with biodegradation of substrates to products.
Several dioxygenases putatively associated with the biodegradation of aromatic compounds were identified particularly in the known aromatic compound degrader strains based on both phylogenetic tree and similarity search approaches, providing valuable information for strain engineering in the field of bioremediation.
Bacteria belonging to the genus Novosphingobium are often associated with the biodegradation of aromatic compounds such as phenol, aniline, nitrobenzene, 4-chlorobenzene, phenanthrene, pyrene, carbofuran, dibenzofuran and estrogen [ 2- 10].
Given what is known about the β-etherase pathway in Sphingobium sp. strain SYK-6, we sought to investigate whether or not this pathway could be utilized for β-ether catabolism by other sphingomonads (bacteria from genera: Novosphingobium, Sphingobium, Sphingomonas, and Sphingopyxis), organisms that are often associated with the biodegradation of aromatic compounds in the environment.
The evaluation of the decline in crude oil quality associated with biodegradation has become critical in recent years as offshore drilling has progressed into deeper water horizons.
Increased desorption of DOM in the form of extracellular polymeric substances (EPS) from EPS Al(OH 3 complexes correlates with an increase in biodegradation of EPS associated with Al(OH 3, suggesting that desorption enhances microbial utilization of DOM [106].
Biodegradation of pollutions is associated with microbial growth and metabolism, i.e., factors that have an impact on the process.
The presence of reduced cysteine residues is often considered as an indirect measure of keratin biodegradation, and is associated with proposed mechanisms of keratinolysis that involved synergistic action of enzymatic or chemical reducing factors (Korniłłowicz-Kowalska and Bohacz 2011).
Also, the group Betaproteobacteria might be associated with benzotriazole biodegradation as this group was, even at the end of the experiment, still the dominant one.
