The present work was carried out with the aim to analyze the secretome of Trametes versicolor BAFC 2234 grown on tomato juice medium supplemented with copper and manganese. T. versicolor BAFC 2234 was selected among diverse wood dwelling agaricomycetes from Argentina by its ability to cause a strong white rot on hardwood and in addition to show high tolerance toward phenolic compounds. A considerable number of the identified proteins were related to the degradation/modification of lignocelluloses. Hydrolases, peroxidases and phenoloxidases were the most abundant enzymes produced under the above-mentioned culture conditions. The lignin-modifying oxidoreductases laccase, manganese peroxidase (MnP) and versatile peroxidase (VP) were successfully purified – the latter for the first time from T. versicolor. The native VP protein has a molecular mass of 45 kDa and an isoelectric point of pH 3.7. The study clearly shows that complex plant-based media being rich in phenolics, such as tomato juice, can stimulate the secretion of a broad set of extracellular lignocellulolytic enzymes. Using such natural products as fungal culture media may give the opportunity to investigate plant biomass decomposition as well as the biodegradation of organic pollutants in an environment close to nature.
