“…Though similar in gross morphology, they have diverse anatomical, physiological, and molecular biological characteristics [15]. Phanerochaete chrysosporium is the most extensively studied white rot fungus due to its effi ciency in attacking a range of condensed aromatic pollutants and lignin [16][17][18][19]. Broader studies of this resupinate group address their biodegradative capabilities [10], and specifi c focus has centered on Dichomitus squalens, Irpex lacteus, and Bjerkandera adusta [2,[20][21][22].…”

Resupinate white rot fungi were isolated from across Thailand (seven provinces) and evaluated for their ability to degrade the recalcitrant and toxic dye reactive black 5 (RB5). Seven of the 13 isolates decolorized RB5 (100 mg/L) within three days (greater than 50%). One isolate, Phanerochaete sordida PBU 0057, yielded complete decoloration within three days. It was active under environmental conditions in which waste dyes are discharged. The degradation of RB5 by P. sordida PBU 0057 was confi rmed by spectrophotometric and HPLC analyses. The degradation was associated with the activities of laccase and lignin peroxidase. Manganese peroxidase was additionally active in the comparative control strain of P. chrysosporium. The degradation dye products produced by P. sordida PBU 0057 were not phytotoxic towards Phaseolus vulgaris, Sorghum bipolar, and Zea mays. Overall, P. sordida PBU 0057 showed somewhat greater dye-degradative activities when compared to the control reference strain P. chrysosporium ATCC 24725 under practical environmental conditions. P. sordida PBU 0057 has potential for application in the biological detoxifi cation treatment of waste dye residues.

“…There are about 10,000 different dyes that are used globally [18]. The textile industry releases about 10% of the above-mentioned value as their effluents in fresh water which was toxic to the environment [15]. The dyes from textile dyeing effluents pose a serious threat to environment even at a very low concentration (1mg/L).…”

|V o l u m e 1 3 N u m b e r 3 J o u r n a l o f A d v a n c e s i n c h e m i s t r in ABSTRACTThe present study was aimed to test the ability of Penicillium citrinum MTCC 8009, Aspergillus terreus MTCC 3006, Bacillus cohnii and their consortia to decolorize basic violet dye. Different parameters such as initial dye concentration, dye to inoculum ratio and period of incubation were studied for the decolourization of the dye. The developed fungal-bacterial consortia exhibited maximum percent decolorization (92%) ability when compared to the treatment of dyes by individual microbes. Percent decolorization of basic violet dye (92%) was more efficient using fungal-bacterial (Penicillium citrinum and Bacillus cohnii) consortia than with individual cultures. Phyto-toxicity results indicated that bacterial-fungal consortia (Penicillium citrinum and Bacillus cohnii) treatment was believed to degrade the dyes to non-toxic intermediates. The FTIR analysis also revealed that decolorization of basic violet dyes was due to its degradation.

“…During disposal, different toxic products can be generated and evacuated through effluents into the environment. Alternative treatment methods, using bacteria or fungi (energy efficient and economical), are currently widely studied [1,5]. Enzymes from certain fungi (laccase, lignin peroxidases and manganese peroxidases) have shown a high ability of degradation of synthetic dyes [3,6].…”

The fungus Pycnoporus sanguineus MUCL 51321 white rot isolated in Gabon showed a high ability to decolorize and degrade two synthetic dyes. On solid and liquid media, the fungus had different enzyme activities (laccase and manganese (Mn) peroxidase) in the presence of different substrates. At concentrations of 0.05 g/L (Orange G) and 0.3 g/L (reactive blue 4), the respective rates of decolorization of 81% and 97% were observed after 15 days of incubation in liquid media. In the same time interval, changes on the spectra (UV-vis and FTIR) and chromatograms (HPLC) showed that these decolorizations were due to the degradation of dyes by fungus with the production of new compounds. The study revealed the possibility of the use of this fungal strain in the microbial degradation process of synthetic dyes. Aldrich (Sigma-Aldrich, St. Louis, MO, USA). All reagents used were of the analytical grade. Journal of Bior emediation & Biodegradation Culture ConditionsThe composition of the solid growth medium used was as follows: 0.2% glucose, 0.2% malt extract, 0.01% MgSO 4 , 0.01% MnCl 2 , 0.03% NH 4 NO 3 , 0.026% KH 2 PO 4 , 0.026% Na 2 HPO 4 , 0.01% CaCl 2 .2H 2 O, 0.0001% FeC1 3 .6H 2 O, 0.0001% ZnCl 2 , 1.6% and 1.6% agar in 1 L of distilled water. The pH was adjusted to 5.5 with hydrochloric acid (0. 5 N) before autoclaving (at 121°C for 15 min). The culture medium was transferred into 4 Erlenmeyer flasks (200 mL each) and each reagent (enzymatic revelation) or dye, depending on its final concentration was added. The mixture was shaken, then about 15 mL were distributed in a Petri dish (diameter 8.5 mm); each test was replicated three times. 50 mL of liquid culture media in flasks of 100 mL were constituted in almost the same way as the solid culture media described above, except for the absence of agar. Each test was conducted three times. Decolorization experimentsDyes decolorization on solid medium: Solid culture media contained different concentrations of each dye (0.05 g/L to 1.5 g/L). Various controls were also prepared: some Petri dishes with fungus alone and others with dye alone to assess possible abiotic decolorization. One square portion of agar (1 cm of diameter) containing the fungus was placed at the centre of each Petri dish. The fungal growth diameters and the halos of decolorization were measured every day during one week at constants temperature (30°C) and humidity (75%). After these measures, different ratios and rates (decolorization or inhibition) were determined as described by . The optimum temperature of decolorization was evaluated using different growth temperatures (15, 22, 30, 35, 40 and 45°C). Moreover, the optimal concentrations for decolorization (0.05 g/L for the Orange G and 0.3 g/L for the RB4) were obtained after one week. All tests were conducted three times (averages are presented with the corresponding standard deviations).Dyes decolorization on liquid culture medium: For each Erlenmeyer flask (100 mL) containing liquid culture medium (50 mL) and dye (0.05 g/L Orange G or 0.3...
