“…Azo dyes make up half of the dyes which are produced annually and are characterized by a nitrogen-nitrogen double bond (Stolz 2001). Bacterial treatment of textiles wastes would be beneficial over fungal treatment because the dyes contained in these effluents are highly variable and bacteria may continue to actively produce enzymes which degrade these dyes without great specificity for growth conditions or dye substrate (Anwar et al 2014;Stolz 2001).…”

“…Bacteria have been isolated from soil, wastewater, lignocellulose, and black liquor. These bacteria are capable of utilizing pulp and paper mill lignocellulosic waste to provide a variety of benefits including decolorizing pulp and paper mill effluent, producing low-molecular-weight compounds, and producing lignocellulose-degrading enzymes (Anwar et al 2014;Chandra 2001;Chandra et al 2007Chandra et al , 2008Chandra and Singh 2012;Chen et al 2012;Ko et al 2007;Mathews et al 2014;Morii et al 1995;Raj et al 2007a, b;Singh et al 2009;Shi et al 2013a, b;Yadav et al 2014). The majority of the bacteria isolated from pulp paper mill effluent are γ-proteobacteria (Acinetobacter, Azotobacter, Citrobacter, Enterobacter, Escherichia, Halomonas, Klebsiella, Pantoea, Providencia, Pseudomonas, and S er r a t i a ) .…”

Lignocellulose is a term for plant materials that are composed of matrices of cellulose, hemicellulose, and lignin. Lignocellulose is a renewable feedstock for many industries. Lignocellulosic materials are used for the production of paper, fuels, and chemicals. Typically, industry focuses on transforming the polysaccharides present in lignocellulose into products resulting in the incomplete use of this resource. The materials that are not completely used make up the underutilized streams of materials that contain cellulose, hemicellulose, and lignin. These underutilized streams have potential for conversion into valuable products. Treatment of these lignocellulosic streams with bacteria, which specifically degrade lignocellulose through the action of enzymes, offers a low-energy and low-cost method for biodegradation and bioconversion. This review describes lignocellulosic streams and summarizes different aspects of biological treatments including the bacteria isolated from lignocellulose-containing environments and enzymes which may be used for bioconversion. The chemicals produced during bioconversion can be used for a variety of products including adhesives, plastics, resins, food additives, and petrochemical replacements.

“…Several bacterial strains such as Providencia sp., Pseudomonas aeuroginosa, Acinetobacter junii, Enterobacter sp., Citrobacter sp., Brevibacillus laterosporus and Bacillus sp. were investigated in terms of their ability to degrade dyes (Wang et al 2009a,b;Kurade et al 2011;Phugare et al 2011;Anwar et al 2014;Yu et al 2015). Most of the studies on bacterial dye degradation are lab-scale investigations focusing on strains' decolourization ability with least attention towards the complexity of the dye biodegradation process in natural conditions.…”

“…Huang et al (2015) described the ability of Lactobacillus paracase CL1107 to coeliminate toxic chromium and Acid Black (ATT) azo dye. Anwar et al (2014) reported that A. junii strain FA10 used for reactive red 120 decolourization exhibited good tolerance to considerable levels of different heavy metals. Pseudomonas aeruginosa strain ZM130 was highly effective in simultaneously removing Cr 6+ and Reactive Red 120, Reactive Black 5, Reactive Yellow 2 and Reactive Orange 16 azo dyes from a simulated wastewater even in the presence of three other heavy metals, Zn, Pb and Cd (Maqbool et al 2016).…”

Aim The effect of heavy metals presence on the decolourization of Reactive Black 5 by Pseudomonas aeruginosa was evaluated. Methods and Results In the current study, a newly isolated strain identified as P. aeruginosa strain Gb 30 was selected for its ability to remove high concentration of Reactive Black 5 and resistance to several heavy metals (Cu2+>Zn2+>Cd2+>Cr6+). Strain Gb30 was used to assess the effect of heavy metals presence on RB5 decolourization. The strain growth exhibited different responses at a fixed concentration of EC50 (10 h) for each heavy metal. The addition of Zn2+ and Cd2+ had no effect on decolourization yield after 24 h of incubation, whereas Cr6+ and Cu2+ ions reduced decolourization up to 17%. In order to understand the relationship between heavy metals contamination and decolourization, experimental data relating the initial decolourization rate of RB5 to the concentrations of single and associated heavy metals were fitted to three different inhibition kinetic models. Conclusions In this study, we showed that P. aeruginosa strain Gb30 could be used for dye removal even at high concentrations of heavy metals. The developed models could provide basic information that may help for the best management of the bacteria‐mediated decolourization process at the industrial scale. Significance and Impact of the Study This study opens new directions for the management of textile industry wastewaters containing dyes and heavy metals using bioaugmentation by P. aeruginosa strain Gb30.
