The authors carried out a time-series study to determine whether short-term increases in the concentrations of spores were associated with emergency department visits from asthma among children 0 to 9 years of age in Montreal, 1994-2004. Concentrations of spores were obtained from one sampling monitor. The authors used parametric Poisson models to model the association between daily admissions ...

BACKGROUND AND AIMS Epipogium aphyllum is a Eurasian achlorophyllous, mycoheterotrophic forest orchid. Due to its rarity, it is often protected, and its biology is poorly known. The identity and pattern of colonization of fungal associates providing carbon to this orchid have not been studied previously. METHODS Using samples from 34 individuals from 18 populations in Japan, Russia and France...

Fungal degradation of wood is mainly restricted to basidiomycetes, these organisms having developed complex oxidative and hydrolytic enzymatic systems. Besides these systems, wood-decaying fungi possess intracellular networks allowing them to deal with the myriad of potential toxic compounds resulting at least in part from wood degradation but also more generally from recalcitrant organic matte...

Establishing the phylogeny of fungi and protists often has proved difficult owing to the simple morphologies and convergent characters in these organisms. We used DNA sequences of nuclear small-subunit ribosomal RNA genes to determine phylogenetic relationships among three major classes of organisms considered to be fungi--Basidiomycetes, Ascomycetes and Chytridiomycetes--and to assess the taxo...

The use of residual lignocellulosic biomass appears as an opportunity to obtain high added value products like enzymes. present work goal was select basidiomycetes capable metabolizing empty fruit bunches (EB) or sludge decanter (SD) from the oil palm industry produce enzymatic cocktails. First, eight macro-basidiomycetes strains Brazilian cerrado were selected based on genomic DNA analyses out...
