Involvement of ligninolytic enzymes of Myceliophthora vellerea HQ871747 in decolorization and complete mineralization of Reactive Blue 220

In the present work, we have reported a sustainable and effective method for the degradation of a textile dye Reactive Red 31 (RR31) using synthesized titanium nanoparticles. Titanium dioxide nanoparticles were synthesized using a noxious weed, Parthenium hysterophorus, as reducing and capping agent for the first time. The synthesized nanoparticles were characterized and confirmed as TiO 2 nanoparticles by using X-ray diffraction spectroscopy, Fourier transformation infrared spectroscopy, and scanning electron microscopy analysis. A glass reactor was designed and developed for the degradation of dye under solar radiations. Photocatalytic degradation of Reactive Red 31 was carried out at different concentrations using synthesized nanoparticles. UV-vis spectroscopy, total organic carbon, and total inorganic carbon analysis were carried out for the determination of dye degradation. The results reveal that biogenic TiO 2 nanomaterial acts as a good photocatalyst for the degradation of textile dye Reactive Red 31.

“…These findings contradict with the previous report of Wang et al (2008), that the degradation of RB5 azo bond by Rhodopseudomonas palustris led to the formation of toxic aromatic compound 7-amino-8-hydroxy-1,3-naphthoquinone-3,6-disulfonate-1,2-diimime. The loss of amino compound (-NH 2 ) that bearing by RB5 was likely mediated by deamination and hydroxylation as these mechanisms were main role of laccase in degrading substrate (Patel et al, 2013). Then, the desulphonation of sulphuric acid mono-[2-(toluene-4-sulfonyl)-ethyl] ester led to the formation of 1,2,4-trimethylbenzene (I) which was detected in the culture extract at earlier incubation.…”

“…In the recent years, a number of studies have focused on using some microorganisms (Chen et al., 2003; Acuner and Dilek, 2004; Mishra and Malik, 2014; Shen et al., 2015; Kurade et al., 2017; Veena et al., 2019) for degrading and absorbing dyes from wastewater. A wide variety of microorganisms including bacteria, fungi, yeast and algae are able to decolorize and degrade a wide range of dyes (Ayed et al., 2010; Kabra et al., 2011; Patel et al., 2013; Saratale et al., 2013; Veena et al., 2019). Under certain conditions, bacteria can rapidly degrade and even completely mineralize many reactive dyes (Chen et al., 2003; Asad et al., 2007; Jadhav et al., 2011; Kurade et al., 2012; Barapatre et al., 2017).…”

Bacteria were isolated from effluents of textile industries and screened by their capability to decolorize at least one of eight reactive dyes used in the textile industries. Three isolates having the capability to decolorize the highest number of dyes with more than 25% of decolorization were identified as Alcaligenes faecalis AZ26, Bacillus cereus AZ27 and Bacillus sp. AZ28 based on morphological, cultural, biochemical characteristics, and 16S rDNA sequence analysis. The decolorization capability of these three bacterial isolates was optimized under different physicochemical conditions by using Novacron Super Black G (NSB-G), one of the eight reactive dyes commonly used in textile industries. These bacterial isolates grew well in the presence of up to 500 mg L −1 of NSB-G and showed decolorization of approximately 90% at 200 mg L −1 of NSB-G after 96 h of cultivation at 37 °C and pH 8.0 under static condition. Decolorization of NSB-G by the bacterial isolates was investigated using UV-VIS spectrophotometry and Fourier Transform Infrared Spectroscopy (FTIR) analysis. The UV-visible absorbance spectra and the FTIR spectrum of the decolorized NSB-G significantly differed from those of the parent dye, indicating that the NSB-G was degraded by the bacterial isolates. High decolorization extent supports the notion that the bacterial isolates reported herein might have potential in the biological treatment of dyeing mill effluents.
