Isolation of the microbiota from wood decay insects and some of their enzymatic activities
2023 - IRG/WP 23-11014
Wood decay organisms have the ability to degrade wood components (cellulose, hemicellulose and lignin) by enzymatic capacities, but these enzymes can belong to the proper organism, or to the associated microbiota. The identification of the microorganisms, as well as their role in the digestion of many substrates not always is very well known.
The wood decay insects produce big damages in wood str...

Effect of volatile organic compounds produced by wood rotting fungi on mycelial growth
2023 - IRG/WP 23-11023
Microorganisms such as fungi or bacteria produce volatile organic compounds (so-called MVOCs: Microbial Volatile Organic Compounds) as metabolites. Some MVOCs have been found to be biologically active, for example inhibition of spore germination, and when fungi of different species encounter each other, the MVOCs pattern change, suggesting that MVOCs play a role as a mediator for biological intera...

Structure bioactivity relationships of softwood knot extracts
2023 - IRG/WP 23-11026
Antibacterial, antifungal and radical scavenging activities of knots of three softwood species have been investigated to evaluate the role of higher amounts of extractives present in knots. The results showed than Douglas fir presented higher scavenging activity than fir and spruce, which present more or less the same activities. Fir and spruce extracts presented higher antibacterial activities th...
