Six strains of white rot fungi were tested for their biodegradation ability of low chlorinated polychlorinated biphenyl (PCB) commercial mixture (Delor 103) in real soil system. Phanerochaete chrysosporium and Trametes versicolor did not show any ability to degrade PCBs in soil. On the contrary, four strains of Pleurotus ostreatus were able to remove about(More)
The ability to decolorize eight chemically different synthetic dyes (Orange G, Amaranth, Orange I, Remazol Brilliant Blue R (RBBR), Cu-phthalocyanin, Poly R-478, Malachite Green and Crystal Violet) by the white rot fungus Dichomitus squalens was evaluated on agar plates. The fungus showed high decolorization capacity and was able to decolorize all dyes(More)
Laccases (benzenediol: oxygen oxidoreductases, EC are copper-containing enzymes that catalyze the oxidative conversion of a variety of chemicals, such as mono-, oligo-, and polyphenols and aromatic amines. Laccases have been proposed to participate in the transformation of organic matter and xenobiotics as well as microbial interactions. Several(More)
The ability to decolorize four synthetic dyes (Phenol Red, Evans Blue, Eosin Yellowish and Poly B411) in fivePleurotus ostreatus strains (a parental strain and four isolates derived from it) was determined. Two of the isolates had markedly higher and other two substantially lower production of ligninolytic enzymes and hydrogen peroxide that the parental(More)
Thirteen basidiospore-derived isolates of Pleurotus ostreatus f6 strain differing in the level of ligninolytic enzyme production and other characteristics (mycelium extension rate, colony morphology) from the parental strain were cultivated on natural substrates. Under these conditions ligninolytic enzyme activity, loss of organic mass, polycyclic aromatic(More)
Thirty different white rot strains were screened for Orange G and Remazol Brilliant Blue R (RBBR) decolorization on agar plates. Three promising strains, Dichomitus squalens, Ischnoderma resinosum and Pleurotus calyptratus, selected on the basis of this screening, were used for decolorization study in liquid media. All three strains efficiently decolorized(More)
The effect of enhanced laccase (Lac) activity (obtained after copper addition to cultivation media) on decolorization of azo dye Orange G in two basidiospore-derived monokaryotic isolates ofPleurotus ostreatus was determined. The high Lac-producing isolate efficiently decolorized Orange G. The low-producing isolate showed only poor decolorization ability(More)
Laccase and other ligninolytic enzyme higher-producing dikaryons of Pleurotus ostreatus were obtained after crossing of compatible basidiospore-derived monokaryons selected from the parental basidiospore population on the basis of exceptionality in enzyme production, mycelium extension rate and/or colony morphology. As all detected changes in enzyme(More)
A new alternative method using perlite as a particulate solid carrier in the growth medium with a cryoprotectant was successfully tested for cryopreservation of several basidiomycete species from different genera (Armillaria, Pleurotus, Pluteus, Polyporus) which failed to survive or retain their properties in cryopreservation procedures routinely used in(More)
A set of 50 randomly chosen fungal strains belonging to different basidiomycete species was tested for H2O2 and ligninolytic enzyme production and for decolorization of synthetic dyes Orange G and Remazol Brilliant Blue R. The decolorization capacity of individual strains was influenced by the level of H2O2 and laccase activity. The strains producing H2O2(More)
