the abilities of aspergillus niger and serpula himantioides to immobilize lead (pb) from lead sulphide (pbs) were investigated. upon growth on potato dextrose agar (pda) amended with pbs which contained 10mm pb, no visible solubilization activity was detected. a. niger produced biomass in greater quantity compared to s. himantiodes in both experimental and control media. with a ratio of 1.13, a...

In the microwave-radiofrequency spectrum, Wi-Fi is a short-range wireless broadband technology, which transmits at frequency of 2.5 GHz. This type technology has been positioned itself as one most widely used technological advances in recent years. It reported that direct exposition to radiofrequencies can induce physiological changes different animals and plants species. One degenerative effec...

Serpula himantioides is a widely distributed saprotrophic fungus that causes root and butt rot in various tree species. In Japan, associated with S. observed Chamaecyparis pisifera Abies sachalinensis. Previous studies have shown includes five phylogenetically defined cryptic lineages, but the placement of Japanese isolates remains unclear. To clarify phylogenetic relationship between known we ...

Serpula himantioides is a wood-decaying fungal pathogen which widespread and causes potentially serious butt rot in living trees of numerous coniferous plantation species. This study aimed to quantify S. the wood Sawara cypress (Chamaecyparis pisifera) with using real-time polymerase chain reaction (real-time PCR). Species–specific primers were designed for internal transcribed spacer 2 (ITS2) ...

Brown rot fungi belong to the wood-rotting fungi, which produce oxalic acid and actively decompose wood. We first found oxalates formed under action of brown in natural conditions on stone (Rogoselga adit, Karelia, Russia), proposed a model for their formation, confirmed hypothesis that frequent occurrence metal mines adits may be associated with activity these fungi. synthesized four species b...

Serpula himantioides (Boletales, Basidiomycota) produces thin resupinate basidiocarps on dead coniferous wood worldwide and causes damage in buildings as well. In this study, we present evidence for the existence of at least three phylogenetically defined cryptic species (referred to as Sib I-III) within the morphospecies S. himantioides, a conclusion based on analyses of sequence data from fou...

The devastating dry rot fungus, Serpula lacrymans, has a worldwide occurrence in buildings. We investigated the genetic variation in European isolates belonging to five vegetative compatibility groups (VCGs) by AFLP analysis. Our results indicate that S. lacrymans in Europe is genetically extremely homogenous; only five out of 308 scored AFLP fragments (1.6 %) were polymorphic. In contrast, S. ...

Six species of Serpula and Spiraserpula were identified, mainly, from the material of the expeditions of the Rosenstiel School of Marine and Atmospheric Science, University of Miami, including two new species of Serpula. Serpula madrigalaesp. n. from the Turks and Caicos has a tube with five longitudinal ridges, four rows of alveoli and a medium-sized shallow symmetrical opercular funnel with 1...
