Beeswax waste improves the mycelial growth, fruiting body yield, and quality of oyster mushrooms (Pleurotus ostreatus)

mycolabadmin

Researchers found that adding beeswax waste to the growing substrate for oyster mushrooms significantly improves their yield and nutritional quality. At optimal levels (5%), mushrooms grown with beeswax waste produced 4% more yield and had 28% more protein than those grown with traditional wheat bran. This discovery offers an environmentally friendly solution for disposing of beeswax waste from beekeeping while producing healthier, more nutritious mushrooms.

Solid-state NMR spectroscopy reveals unique properties of Trichoderma harzianum cell wall components

mycolabadmin

Scientists used advanced spectroscopy techniques to examine the cell wall structure of Trichoderma harzianum, a beneficial fungus used to protect crops from harmful fungi. They discovered that this fungus has a uniquely organized cell wall composed of tough chitin layers inside and flexible sugar polymers outside. This special arrangement helps protect the fungus from dissolving itself with its own powerful enzymes while allowing it to attack pest fungi effectively.

Saprotrophic Wood Decay Ability and Plant Cell Wall Degrading Enzyme System of the White Rot Fungus Crucibulum laeve: Secretome, Metabolome and Genome Investigations

mycolabadmin

This study investigates how a forest fungus called Crucibulum laeve breaks down wood and plant material. Using specialized laboratory techniques, researchers found that this fungus uses a unique set of enzymes that work through oxidation (chemical breakdown using oxygen) rather than simple digestion. The fungus is particularly good at degrading birch wood and produces numerous copies of genes for these special enzymes, giving it an advantage in decomposing partially rotted plant material on the forest floor.

Wood decay under anoxia by the brown-rot fungus Fomitopsis pinicola

mycolabadmin

Researchers discovered that a common wood-decaying fungus called Fomitopsis pinicola can break down wood even when there is no oxygen present, which happens in the interior of fallen trees. Instead of using the chemical process it normally uses in oxygen-rich conditions, the fungus switches to releasing powerful digestive enzymes that break down plant fibers. This finding explains how wood continues to decompose deep inside tree trunks and could inspire new industrial processes for breaking down plant material without oxygen.
