“…Further increase in temperature results in decreased the percentage decolorizations in both Coriolus versicolor and Pleurotus ostreatus. This study was in consistent to the study by Asgher et al (2009);Naghdi et al (2013) and Venkatachalam and Venkatachalam (2008), whom observed that decolorization of dye stuffs by white rot fungi work best at moderate temperatures. The decrease in decolorization at higher temperatures could be due to denaturation of enzymes resulting from the breakdown of the weak ionic and hydrogen bonding that stabilizes the 3-dimensional structure of the enzyme active site.…”

Synthetic dyes are widely used by different industries with over 7 ×10 5 metric tons produced globally each year. Dyes pose adverse effects including chemical oxygen demand, visual pollution, cytotoxicity, genotoxicity, mutagenicity and carcinogenicity on various types of living organisms. The versatile white rot fungi (basidiomycetes fungi) have developed specialized ligninolytic enzymes for reductive cleavage of dyes and xenobiotics. The present study optimized the decolorization of Remazol brilliant blue royal (RBBR) dye by enzymatic extracts of Coriolus versicolor and Pleurotus ostreatus. Experiments were carried out by varying one parameter i.e. pH (2.5-6.5), temperature (30 o C-60 o C), enzyme activity (3.3U-20U), dye concentration (10mg/L-125mg/L) and time (0-480mins), while others constant to study its effects on decolorization of RBBR. From the results obtained, the optimum conditions for decolorization of RBBR by extracts of C. versicolor and P. ostreatus were pH 4.0, temperature of 30 0 C, enzyme activity 20U, dye concentrations of 100mg/L and 50mg/L for C. versicolor and P. ostreatus respectively at the end of 480 minutes. At the optimized conditions, decolorizations for C. versicolor and P. ostreatus were 80.42% and 70.42% respectively. Highest laccase activity (19.50U) was recorded in C. versicolor compared to P. ostreatus (1.41U).

“…The electrical properties of polymeric phthalocyanine are of interest because of their conjugated structure and stability against light, heat, moisture, and air. Hence polymeric phthalocyanines are suitable candidates for use as environmentally stable electrically conductive materials [11][12][13][14].…”

A novel indigenous strain, Phanerochaete chrysosporium IBL-03, with high manganese peroxidase (MnP) activities was used for decolorization of a reactive textile dye, Drimarine Blue K2R, which is used extensively in textile units of Pakistan. The initial experiment was run for seven days with 0.01% (w/v) dye solution prepared in Kirk's basal nutrient medium. Samples were removed after every 24 h and the extent of dye decolorization was determined at lambda(max) of the dye. The study revealed that P. chrysosporium caused 65% decolorization of Drimarine Blue K2RL in seven days. By process optimization, 97% colour removal could be achieved in three days using 0.005% (w/v) Drimarine Blue K2RL solution at pH 4.0 and 30 degrees C in defined Kirk's medium with 0.9% (w/v) molasses and 0.2% (w/v) ammonium dihydrogen phosphate added as carbon and nitrogen sources, respectively. Manganese peroxidase was found to be the major enzyme (560 IU/mL) involved in dye decolorization of Drimarine Blue K2RL by P. chrysosporium. The dye adsorption studies showed that the dye initially adsorbed on fungal mats disappeared later on, possibly by the action of MnP secreted by the fungus in secondary metabolism.
