Adding biochar to soil has environmental and agricultural potential due to its long-term carbon sequestration capacity and its ability to improve crop productivity. Recent studies have demonstrated that soil-applied biochar promotes the systemic resistance of plants to several prominent foliar pathogens. One potential mechanism for this phenomenon is root-associated microbial elicitors whose presence is somehow augmented in the biochar-amended soils. The objective of this study was to assess the effect of biochar amendment on the root-associated bacterial community composition of mature sweet pepper (Capsicum annuum L.) plants. Molecular fingerprinting (denaturing gradient gel electrophoresis and terminal restriction fragment length polymorphism) of 16S rRNA gene fragments showed a clear differentiation between the root-associated bacterial community structures of biochar-amended and control plants. The pyrosequencing of 16S rRNA amplicons from the rhizoplane of both treatments generated a total of 20,142 sequences, 92 to 95% of which were affiliated with the Proteobacteria, Bacteroidetes, Actinobacteria, and Firmicutes phyla. The relative abundance of members of the Bacteroidetes phylum increased from 12 to 30% as a result of biochar amendment, while that of the Proteobacteria decreased from 71 to 47%. The Bacteroidetes-affiliated Flavobacterium was the strongest biochar-induced genus. The relative abundance of this group increased from 4.2% of total rootassociated operational taxonomic units (OTUs) in control samples to 19.6% in biochar-amended samples. Additional biochar-induced genera included chitin and cellulose degraders (Chitinophaga and Cellvibrio, respectively) and aromatic compound degraders (Hydrogenophaga and Dechloromonas). We hypothesize that these biochar-augmented genera may be at least partially responsible for the beneficial effect of biochar amendment on plant growth and viability.

“…Aerobic degradation is a multiple step process and may include autoxidation, desulfonation, demethylation and deamination reactions (Oturkar et al, 2011;Singh, 2006). Gan et al (2011) reported that different enzymes such as protocatechuate dioxygenases and aromatic ring hydroxylases are responsible for the cleavage of aromatic rings. Similarly, Dawkar et al (2008) reported that laccases are involved in the demethylation of aromatic compounds.…”

“…Overall, there is a wide variation in the oxidative degradation of different aromatic amines. For example, in one study, Gan et al (2011) depicted the mineralization of 4-aminobenzensulfonate by Ralstonia and Hydrogenophaga sp. In this mineralization process, oxygen was introduced and degradation occurred through aromatic ring hydroxylation carried out by dioxygenase enzymes following a beta-ketoadipate pathway (Parales & Resnick, 2006).…”

Azo dyes and their intermediate degradation products are common contaminants of soil and groundwater in developing countries where textile and leather dye products are produced. The toxicity of azo dyes is primarily associated with their molecular structure, substitution groups and reactivity. To avoid contamination of natural resources and to minimize risk to human health, this wastewater requires treatment in an environmentally safe manner. This manuscript critically reviews biological treatment systems and the role of bacterial reductive and oxidative enzymes/processes in the bioremediation of dye-polluted wastewaters. Many studies have shown that a variety of culturable bacteria have efficient enzymatic systems that can carry out complete mineralization of dye chemicals and their metabolites (aromatic compounds) over a wide range of environmental conditions. Complete mineralization of azo dyes generally involves a two-step process requiring initial anaerobic treatment for decolorization, followed by an oxidative process that results in degradation of the toxic intermediates that are formed during the first step. Molecular studies have revealed that the first reductive process can be carried out by two classes of enzymes involving flavin-dependent and flavin-free azoreductases under anaerobic or low oxygen conditions. The second step that is carried out by oxidative enzymes that primarily involves broad specificity peroxidases, laccases and tyrosinases. This review focuses, in particular, on the characterization of these enzymes with respect to their enzyme kinetics and the environmental conditions that are necessary for bioreactor systems to treat azo dyes contained in wastewater.

“…Therefore, bacteria are not easily taken up by these compounds (Tan et al, 2005). In textile industries, sulfonated azo dyes are commonly used since they bond more strongly to the fiber and have lower toxicity than their non-sulfonated analog (Gan et al, 2011). Besides, the lower hydrophobicity of aromatic amines leads to less inhibitory among N-substituted aromatics, which are generally reactive toxicants (Razo-Flores et al, 1997;Chen et al, 2008).…”

a b s t r a c tA lab-scale UASB reactor was operated for the treatment of p-acetamidobenzene sulfonyl chloride (p-ASC)-containing wastewater with and without ethanol for 210 days. The influence of the organic loading rate on the performance of reactor by step-decreasing HRT reduction/step-increasing the concentration of p-ASC was evaluated. Almost complete degradation of 50 mg/l p-ASC and COD removal efficiency (79.5%) was noticed with a COD removal of 79.5% at HRT of 0.5 day or longer and an applied p-ASC loading rate below 120 mg/l/day. No inhibition to the performance of this reactor was observed even at a p-ASC concentration up to 1000 mg/l. Of interest that despite the absence of sulfate in the feed, a certain quantity of sulfate and sulfide was simultaneously generated in the effluent. The trial result in the absence of ethanol demonstrated that p-ASC could be used as the sole source of carbon and energy. Clone libraries for the archaeal and bacterial communities were constructed for a biomass sample taken on day 190. The majority of bacterial clones were represented by Proteobacteria, followed by Thermotogae, Bacteroidetes and Firmicutes. Bacterial groups within the phyla Clostridia might be responsible for the desulfonation of p-ASC.
