“…. The spectral setup observed was found similar to that reported in other photodegradation reports (Gahlout et al, 2013;Neoh et al, 2015). recombination sites have to be reduced by synthesizing a photocatalysts with better crystallinity (Ângelo et al, 2013).…”

Lenzites elegans, a ligninolytic enzyme producing white rot fungus with proficient synthetic dye decolourization ability was isolated from decaying wood. To the extent of our knowledge, this is the first report of laccase (362.7 IU/mL) and lignin peroxidase (5.17 IU/mL) production by L. elegans KSG32. The synthetic dye decolorizing ability of the fungus was checked using solid and liquid media. The organism showed greater ability for decolourization of naphthol green B (97%) and bromophenol blue (88%) in the submerged condition followed by partial decolourization for two azo dyes, namely, orange G (70%) and congo red (62%). This is an indicative of the potential application of L. elegans KSG32 in decolourization of colored industrial effluent. The FTIR analysis of the decolourized dye sample showed that major bonds in the dye were broken and oxidation process also increased. The analysis of biomass content showed no growth inhibition of L. elegans KSG32 in the presence of dyes, indicating the less toxicity of these dyes on fungal growth. for 15 min. The moisture content was adjusted to 90% using 0.1 M citrate buffer (pH 5). Three mycelial plugs of size 1 cm2 from 6 days old PDA plate culture were used as inoculum. Inoculated flasks were incubated at room temperature for 5 days. Keywords: Extraction of crude enzymeAfter incubation, the crude enzyme was extracted by adding 50mL 0.1 M citrate buffer (pH 5) to each flask. The culture supernatant was collected after centrifugation at 10,000 rpm for 10 min at 4 C and stored at 4 C.

“…In addition, some studies have reported the presence of carbon and nitrogen sources acting as co-substrates, favoring decolorization and stimulating enzyme production (Levin et al 2010, Andrade et al 2013, Gahlout et al 2013. Hou et al (2004), reported laccase production associated with low nitrogen concentration in culture.…”

Reactive dyes are found in the final effluents of the textile industry and cannot be removed by conventional treatment processes. The use of basidiomycetes appears to be an effective strategy to degrade dye molecules. In this paper, the parameters that favor decolorization of diazo dye were assessed using basidiomycetes immobilized in Luffa cylindrica. Different concentrations of saccharose and urea were assessed, in addition to the introduction of an enriched synthetic effluent. Results showed that the best decolorization occurred at the highest concentration of saccharose and the lowest of urea. It was observed a high biosorptive capacity of the solid support, which decreased when the effluent was enriched with saccharose and urea due to consequent increase in microbial activity. Using the enriched effluent, Pleurotus ostreatus decolorized about 70% within 48 hours, and Trametes villosa decolorized 58% after 240 hours. Peniophora cinerea did not respond to the conditions tested.
