“…LT10 and its 16S rDNA sequence was deposited in NCBI Genebank with accession number KY492394. The previous published data indicated that few bacteria, which belong to genus Pseudomonas have already been reported for their potential to declorize several dyes (Jadhav et al, 2010;Maqbool et al, 2016;Hafeez et al, 2018). However, the bacteria isolated in this study i.e., Pseudomonas sp.…”

“…Such variation might be due to variation in decolorizing capabilities of the isolates and their involved enzymatic systems. Such variation has also been described in different studies dealing with bacterial decolorization of several azo dyes (Maqbool et al, 2016;Hafeez et al, 2018;Maqbool et al, 2018). However, this study is different from others because in this study the decolorization was conducted in the existence of 200 mg/L of Zn.…”

“…LT10 is exceptional in the sense that it has considerable ability for RY2 decolorization even in the presence of Zn. Very recently, Hafeez et al (2018) reported the decolorizing ability of a bacterium, which belonged to genus Pseudomonas in the presence of lead (Pb). Hence, the isolation of Pseudomonas sp.…”

“…Moreover the existence of metal ions including zinc, cadmium, chromium, copper, nickel etc. significantly affect the dye decolorizing activity of bacterial strains (Hafeez et al, 2018;Maqbool et al, 2018). As these metal ions are also a component of the textile wastewaters, hence, there is need to isolate and characterize bacterial strains able to decolorize azo-dyes while tolerating the existence of such metal ions.…”

The textile effluents contain the synthetic dyes, which are mostly discharged into water resources without prior treatment. These dyes are very harmful for aquatic life and microorganisms but also for human beings. These harmful effects become further severe because the metal ions are present along with the dyes. Hence, there is need to deal these pollutants simultaneously. Therefore, present study was carried out to isolate and characterize a bacterium, which showed efficient color removal of reactive yellow-2 (RY2) in occurrence of zinc (Zn). For this purpose, Zn tolerant bacterial strains were isolated and examined for efficient color removal of RY2 in occurrence of Zn. Among the isolated bacterial strains, degrading capabilities of most effective strain, Pseudomonas sp. strain LT10 were characterized under different conditions. In existence of Zn, the strain LT10 exhibited significant decolorization of RY2 and other azo dyes. Moreover, yeast extract as a carbon co-substrate, showed efficient color removal of RY2 at pH 7.5-8.5 by the strain LT10. Moreover, the strain LT10 also revealed considerable decolorization of RY2 even at high levels of Zn. On the basis of results, it can be concluded that Pseudomonas sp. LT10 can be an efficient bioresource for treating textile wastewaters containing azo dyes and metal ions.

Reactive dyes are pernicious pollutants in textile effluent, which are to be treated passably before discharging into the environment. In the present study, a potential dye degrading bacterial strain Pseudomonas guariconensis was isolated from paddy rhizosphere and was characterized by 16S rRNA gene sequencing. The biodegradation ability of the strain was evaluated by time‐based study with immobilized bacterial cells in calcium alginate biocarrier matrix and also with free cells. The results indicated that the strain exhibited maximum degradation of 91% when immobilized in the biocarrier matrix. The enzymatic study revealed the production of oxidoreductase enzymes. The degraded products were identified as 2‐amino‐3‐phenylpropanoic acid and benzoquinone by gas chromatography–mass spectroscopy (GC‐MS) analysis, and a degradative pathway was derived based on the enzymatic profile. A packed bed column was designed using P. guariconensis VITSAJ5 immobilized in calcium alginate beads as a biosorbent for the removal of Reactive Red 120. The immobilized bacterial cells exhibited 87% uptake of RR120, whereas the nonimmobilized bacterial cells exhibited a maximum uptake of 37%. The phytotoxicity analysis by seed germination assay revealed an enhanced plumule and radicle length, indicating the nontoxic byproducts after the treatment of Reactive Red 120 by VITSAJ5 compared to the untreated Reactive Red 120 solution. Practitioner points Current study is the first report on Pseudomonas guariconensis capable of degrading reactive dyes (Reactive Red 120) It was observed that the degradation potential was maximum when cells were immobilized with Ca‐Ag biocarrier matrix Breakdown metabolism of Reactive Red 120 was derived through pathway prediction Employing immobilized bacteria in a packed bed column found to possess a prominent biosorption ability on the matrix enhancing the degradation process Toxic reactive dye was converted into nontoxic compounds, evidenced by phytotoxicity studies
