Basidiocarps of Trametes versicolor with an epiphytic flora (including Trebouxia sp.) collected from north-central Rhode Island were incubated in an atmosphere of C labeled CO2 for 6 hours. Using autoradiography, the location of the fixed CO2 was determined at 6h, 12h, 24h, 48h, 96h, and 192h. The fixed C was recorded in the epiphytic algae after 6h, and at all subsequent times. After 192h the ...
Separation of Trametes versicolor laccase from a commercial preparation was carried out using Three-Phase-Partitioning (TPP) technique. The conditions were optimized and the most favorable ammonium sulphate concentration (70% w/v), crude to t-butanol ratio (1.0:2.0) and pH (4.5) resulted in 56.22% yield with 1.65-fold purity of laccase. For further improvement in purification, an improved versi...
Trametes species have been used for thousands of years in traditional and conventional medicine for the treatment of various types of diseases. The goal was to evaluate possible antigenotoxic effects of mycelium and basidiocarp extracts of selected Trametes species and to assess dependence on their antioxidant potential. Trametes versicolor, T. hirsuta, and T. gibbosa were the species studied. ...
This paper reports the production of ligninase enzymes by a new strain of Trametes versicolor IBL-04 producing a novel pattern of ligninolytic enzymes with highest MnP activities followed by LiP and laccase. In previous studies Trametes versicolor has been reported to produce higher activities of MnP, followed by laccase and LiP. Lignocellulosic substrates including wheat straw, rice straw, ban...
Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.) has been an important afforestation species in northeast China. It has obvious defects of buckling and cracking easily, which are caused by its chemical components. Trametes versicolor (L.) Lloyd, a white-rot fungus, can decompose the cellulose, hemicellulose, and lignin in the wood. White-rot fungus was used to biologically degrade Chinese fi...
Laccases enzyme provide a promising future in terms of its use for the treatment of Malachite green (MG), which is highly toxic residue for aquatic animals. The objectives of this study were the production, purification and characterization of a laccase from Trametes versicolor 50001 with a degrading ability on malachite green. Trametes versicolor 50001 was used to produce laccase enzyme under ...
Background and purpose: Alcoholic liver disease (ALD) such as alcoholic steatosis, hepatitis and cirrhosis are complex multistep chronic diseases reported in many animal studies. Chronic alcohol consumption induces hepatic oxidative stress due to increased generation of reactive oxygen species and/or reduced antioxidant capacity. Trametes versicolor belongs to the more advanced Basidiomycetes c...
The aim of this electrochemical study was to ascertain which position of hydroxy groups on a benzene ring provides electroactive products after enzymatic oxidation by laccase originating from the Trametes versicolor mushroom, exhibiting intense redox signals that are exploitable for their amperometric determination. The electrochemical properties of phenol together with all isomers of benzenedi...
The white-rot fungi produce wide range of extracellular enzymes (especially ligninolytic enzymes) and they can degrade complicated and difficult degradable compounds. An immobilization of enzymes causes their stability, reusability and cheapness, so they could be effectively used in biotechnologies and other branches. In this work we focused on the optimization of isolation procedure namely pre...
