“…Our results indicated that both discoloring strains studied were the degraders of the cellulose of the sawdust treated with the copper-based preservative, though the degree and the time of degradation differed. Certainly, the cellulose decay by wood-rot fungi is considerably more efficient and can reach over 90 % [32]. Our results seem to be consistent with other researchers who found the loss of cellulose in wood by softrot fungi from 10 to 60 % [33].…”

As cases of treated wood colonization by fungi still happen, the understanding of fungal survival abilities could contribute in the creation of new efficient preservatives. For that reason, two dematiaceous fungi Alternaria tenuissima and Ulocladium consortiale isolated from treated wooden joists with discolorations were tested for their wood decomposition ability and tolerance to a copper based preservative. Our results indicated that the copper based preservative failed to suppress completely cellulose and lignin biodegradation by discoloring fungi studied in wood. Moreover, cellulose degradation was higher in the treated sawdust for both fungi after 30 days than in the untreated. Comparing the results of two strains U. consortiale that is little studied as a wood decomposer, was stronger lignin degrader than A. tenuissima in treated and untreated sawdust. The copper sulphate tolerance test showed that both fungi were able to grow up to 7 mM concentration in a solid medium. DOI: http://dx.doi.org/10.5755/j01.ms.25.3.20563

“…Our data are consistent with the known natural ecologies of the fungal species tested. T. versicolor typically grows on dead or decaying wood, which contains a limited set of poly- Tables 1 and 2, respectively. mers, mostly cellulose, lignin, and xylan (39). C. acutatum and P. expansum are some of the most important fungal pathogens of fruits including apples (40,41) and are therefore well adapted to grow on apple pomace medium.…”

Background: There is a growing discrepancy between the putative identification and the empirical characterization of carbohydrate-active enzymes (CAZymes). Results: We have developed a new versatile and high throughput microarray-based method for screening CAZymes. Conclusion:The method is a powerful addition to the enzyme screening toolbox. Significance: The technique enables the rapid screening of CAZymes and facilitates our biological understanding and industrial utilization.

“…Cupul et al [25] achieved maximum MnP activity in cultures of T. maxima at the 10 th day of growth; Irbe et al [12] detected higher MnP activity after 14 days cultivation of T. versicolor; Knezevic et al [6] found maximum MnP activity after 14 days of growth of T. multicolor, Elisashvili and Kachlishvili [6] optimized MnP secretion by T. pubescens after 11 days of solid-state fermentation. This shows that T. villosa exhibits MnP activity peak after similar cultivation time to other species of the genus.…”

Manganese peroxidase (MnP) is a ligninolytic enzyme that is involved in the removal of lignin from the cell wall of plants. This removal facilitates the access of hydrolytic enzymes to the carbohydrate polymers that are hydrolyzed to simple sugars, which allows the subsequent fermentation to obtain bioproducts, such as ethanol. In this work, response surface methodology (RSM) was employed to optimize the culture conditions on unexpensive substrate for MnP secretion by Trametes villosa. Three independent variables were evaluated (i.e., temperature, moisture content and pH). The crude extract containing MnP was used in the delignification experiment and it caused a reduction in lignin content for all residues tested: 35.05 ± 1.45 (%) for the sugar cane bagasse; 63.11 ± 0.06 (%) for the sisal fiber and 39.61 ± 0.39 (%) for the coconut shell, under the reaction conditions tested after 4 hours of fermentation. The preliminary results exhibited the potential application of this enzyme in the removal of lignin from plant residues. However, the conditions should be evaluated and optimized for each residue type.
