“Ganoderma applanatum”

Medicinal and edible lignicolous fungi as natural sources of antioxidative and antibacterial agents.

The antioxidant activity of organic extracts of eight fungal species, Ganoderma lucidum, Ganoderma applanatum, Meripilus giganteus, Laetiporus sulphureus, Flammulina velutipes, Coriolus versicolor, Pleurotus ostreatus and Panus tigrinus, was evaluated for free radical (DPPH(·) and OH(·)) scavenging capacity and an effect on lipid peroxidation, and the antibacterial activity was tested by the agar well diffusion method. The highest DPPH(·) scavenging activity was found in the methanol extract of G. applanatum (12.5??g/mL, 82.80%) and the chloroform extract of G. lucidum (510.2??g/mL, 69.12%). The same extracts also showed the highest LP inhibition (91.83%, 85.09%) at 500??g/mL, while the methanol extracts of G. applanatum and L. sulphureus showed the highest scavenging effect on OH(·) radicals (68.47%, 57.06%, respectively) at 400??g/mL. A strong antibacterial activity against Gram-positive bacteria was also manifested. The antioxidative potencies correlated generally with the total phenol content (0.19-9.98?mg/g). The HPLC determination showed that the majority of analysed species contained gallic and protocatechic acids. Consequently, these fungi are shown to be potential sources of antioxidative and antibacterial agents. Copyright © 2010 John Wiley & Sons, Ltd.[…]

Selection of white-rot basidiomycetes for bioconversion of mustard (Brassica compestris) straw under solid-state fermentation into energy substrate for rumen micro-organism.

Coriolus versicolor and P. chrysosporium were the promising fungus for MS bio-delignification. SIGNIFICANCE AND IMPACT OF THE STUDY: Coriolus versicolor treated MS improved dry matter digestibility and protein content.
