It has been widely reported that the white rot basidiomycete Phanerochaete chrysosporium, unlike most other white rot fungi, does not produce laccase, an enzyme implicated in lignin biodegradation. Our results showed that P. chrysosporium BKM-F1767 produces extracellular laccase in a defined culture medium containing cellulose (10 g/liter) and either 2.4 or 24 mM ammonium tartrate. Laccase acti...

Proposed is a method to investigate degradation of lignocelluloses by pure cultures of basidiomycetes using preserving jars with vermiculite as reservoir for water and nutrients. Bamboo samples of Gigantochloa atroviolacea and Phyllostachys pubescens and wood samples of Fagus sylvatica and Pinus sylvestris were inoculated with the brown-rot fungus Coniophora puteana and the white-rot fungus Sch...

Basidiospores of wood-rotting basidiomycetes are a primary source of infection causing wood biodeterioration, especially in wood above ground. Most studies evaluating wood preservatives have used mycelia or basidiospores obtained from wild mushrooms. The objecting of this study was to demonmtrate in virto methods that promote carpogenesis and basidiosporogenesis by the brown-rot fungi Antrodia ...

Abies sibirica Ledeb.-dominated stands degradation is of special concern. Nevertheless, insufficient attention paid to the role pathogens in this process. The aim present study assess coenotic infectious diseases fir-dominated south Central Siberia. research was based on a forest pathological examination conducted A. sibirica-dominated Krasnoyarsk Krai. cenotic identified unequal. Stem decay an...

BACKGROUND White-rot fungi are primarily the major degraders of lignin, a major obstacle for commercial exploitation of plant byproducts to produce bioethanol and other industrially important products. However, to improve their efficacy for lignin degradation, it has become necessary to genetically modify these organisms using appropriate vectors. Agrobacterium tumefaciens, a soil phytopathogen...

A major part of Trichoderma antifungal system consists of a number of genes encoding for an astonishing variety of secreted lytic enzymes including; e.g. chitinase, cellulases and β-1,3glucanases. The present work aimed to apply the mutagenesis technique in genetically breeding program of the bioagent Trichoderma viride to enhance three effective hydrolytic enzymes in their biocontrol abilities...

Chitosan (C) is a natural antimicrobial compound that has been widely explored for wood protection, but its application limited by high leachability. Genipin biobased crosslinking agent can crosslink with chitosan under mild conditions. This study aims at examining the decay resistance and leachability of genipin-crosslinked (GC) treated against common wood-decaying fungi. GC formation was conf...

The postharvest life of mango is limited by the development of pathogens, especially fungi that cause rot, among which stands out the Lasiodiplodia theobromae. Several control methods have been employed to minimize the damages caused by this fungus, chemical control can leave residues to man and nature; physical control by the use of gamma radiation in combination with modified atmosphere and c...

In this study, the antifungal activities of cinnamaldehyde and eugenol congeners against white-rot fungus Lenzites betulina and brown-rot fungus Laetiporus sulphureus were evaluated and the relationships between the antifungal activity and the chemical structures were also examined. Results from antifungal tests revealed that cinnamaldehyde, alpha-methyl cinnamaldehyde, (E)-2-methylcinnamic aci...
