Antimicrobial Activity of Different Collections of Medicinal Polypore Fungus Fomitopsis pinicola (Agaricomycetes).

The study of antimicrobial activity (AMA) of 14 genetically identified dikaryotic strains of red belted medicinal polypore Fomitopsis pinicola isolated from Betula sp. and other deciduous trees, as well as conifers Picea sp. and Abies alba in Russia, France and Italy against test fungi and bacteria is discussed.

Structure Analysis of the MatA Locus of Sexual Compatibility in the Edible Mushroom Pleurotus ostreatus.

The edible oyster mushroom Pleurotus ostreatus is one of the most cultivated species worldwide. Morphogenesis associated with the maturation of fruit bodies is controlled by two unlinked loci of sexual compatibility matA and matB with multiple alleles (tetrapolar system of sexual compatibility). Quantitative analysis of the alleles of mating compatibility loci in 17 natural isolates collected in the Moscow region was performed in mon-mon (monokaryons-monokaryon) and di-mon (dikaryon-monokaryon) crossings.

Antiproliferative and antibacterial activity of extracts of strains grown in vitro.

In this bioprospecting study the biological activities of extracts of the in vitro culture of Mexican strains were evaluated. The extracts were tested by the Sulforhodamine B staining method for antiproliferative activity and the plate microdilution method for antibacterial activity. Extracts that proved bioactive in these two activities, the antioxidant activity (Galvinoxyl, ABTS, and DPPH) and total phenolic contents (Folin-Ciocalteu) were additionally determined, as well as acute toxicity ().

Biological Activities of Different Strains of the Genus Ganoderma spp. (Agaricomycetes) from Mexico.

Antiproliferative, antioxidant, and antibacterial activities were determined for 14 extracts obtained with a mixture of chloroform-methanol (1:1) from the mycelial cultures of 14 wild strains of the genus Ganoderma collected in the central-south part of Veracruz Province, Mexico. Identification of the strains collected was confirmed based on rDNA internal transcribed spacer phylogenetic analysis. The strains G.
