Armillaria mellea is a commonly harvested and consumed mushroom in Poland. Several activities of polysaccharides from this species have already been reported. However, A. growing the wild Poland not yet investigated. This study was conducted to obtain crude polysaccharide fraction (AmPS) investigate its chemical composition biological properties. Our research suggests that valuable source polys...

DNA sequences (~3 kb long) extending from the intergenic spacer 1 (IGS1) region to the 18S gene were obtained for isolates of Armillaria ostoyae, Armillaria calvescens, Armillaria gallica, and Armillaria sinapina. Additional investigation of 16 A. ostoyae, 11 Armillaria gemina, 21 A. calvescens, 18 A. gallica, and 15 A. sinapina isolates produced 117 sequences spanning the 3’ end of the IGS1 th...

White-rot fungi can degrade a wide spectrum of environmental pollutants, including pharmaceuticals, which are not efficiently removed from wastewater by conventional methods, e.g., the activated sludge method. However, treatment with use fungal cultures (mycoremediation) also has significant limitations: among others, need to appropriate, often-expensive culture media. We aimed screen 18 media ...

Rhagoletis pomonella (Diptera: Tephritidae) populations in North America have diverged by exploiting host plants with varying fruiting phenologies in environments that differ markedly in temperature and humidity. As a result, four genetically and ecologically distinct R. pomonella populations that display partial reproductive isolation have evolved. Host shifting by Rhagoletis and similar evolu...
