“…Most of the bacterial isolates from KTM were previously reported to be used in the degradation of dyes and related products [57][58][59][60][61][62][63]. Bacterial isolates sequentially adapted against higher concentration of four different dyes (Ar 151, Or II, Sb and Db K 2 RL) on solid medium exhibited varying MRLs ranging from 50 to 750 mg l −1 .…”

“…It has been reported that Aeromonas sp. could degrade azo dyes under either anaerobic or aerobic conditions (Du et al, 2015;Idaka et al, 2008;Shah, 2014). However, A. jandaei strain SCS5 could decolorize and degrade MR under both anaerobic and aerobic conditions suggesting that A. jandaei strain SCS5 would have high potential in the removal of azo dye MR.…”

a b s t r a c tIn this study, the decolorization and degradation of methyl red (MR) by suspended and immobilized cells of Aeromonas jandaei strain SCS5 under anaerobic and aerobic conditions have been investigated. The complete decolorization of MR at a concentration of 100 mg L À1 by A. jandaei strain SCS5 was obtained within 6 h for both anaerobic and aerobic suspended cultures, where the decolorization rate was faster in acidic conditions than basic conditions. The decolorization efficiency under 6 h increased with increasing cell mass of inoculation and decreased with increasing initial dye concentrations. Immobilized cells of A. jandaei strain SCS5 could decolorize MR, and the decolorization rate was significantly enhanced by cells immobilized with mediators such as anthraquinone-2,6-disulphonate and magnetic Fe 3 O 4 nanoparticles compared to immobilized cells only. Moreover, the immobilized bacterial beads with mediators retained high decolorization activity up to more than 10 repeating cycles. UVevisible spectra (200 e800 nm) and gas chromatography-mass spectrometry analysis demonstrated that MR was degraded by A. jandaei strain SCS5 through reductive cleavage of azo bond. MR degradation products showed less phytotoxicity against Triticum aestivum and Phaseolus mungo compared to untreated MR. This study has demonstrated that A. jandaei strain SCS5 could be a promising microbiological agent for the removal of azo dyes from the environment.

“…The result of the study also supports the findings of this study. Linear relationships amongst these parameters were observed [7,8,9]. Most of these parameters are found to exceed beyond permissible limit and warrants treatment.…”

Pulp and paper are manufactured from raw materials containing cellulose fibers, generally wood, recycled paper, and agricultural residues. In developing countries, about 60% of cellulose fibers originate from nonwood raw materials such as bagasse (sugar cane fibers), cereal straw, bamboo, reeds, esparto grass, jute, flax, and sisal. Large amount of toxic effluent is released during process of paper production. Pulp and paper mill spent wash (raw effluent) is highly acidic in nature with high BOD, COD, TDS, TSS, phenol, sulphate, nitrogen, phosphorus, potassium and metals viz. Mn Zn Cu Ni Fe and Na . Effluent was treated with chemicals FeCl 3 and KMnO 4 . pH was found to increase from 7.8 to 8. 4
