Abstract:
... Current knowledge concerning 'decomposer' Basidiomycota in Arctic and Antarctic ecosystems is based on two sources: (a) collections and surveys of basidiomata, which have resulted in high-quality catalogues of species, although much of the species' distribution and ecology are tentative and (b) isolations from soils and plant litter which typically result in a “low incidence of basidiomycetes” [Do ...

Abstract:
... 2,4,7,9-tetramethyl-5-decyne-4,7-diol (TMDD) is a high-production volume chemical used in paper, ink, pesticide, and adhesive industries as a wetting and anti-foaming agent. The physicochemical properties and slow biodegradation rate of TMDD indicate a low bioaccumulation potential but a high prevalence in the environment. As a consequence, TMDD has been detected in several European rivers in the ...

Abstract:
... Procedures for the analysis of turnover of chemicals (and of natural compounds) are well developed using radio or stable isotope labelled tracer compounds in various standardized OECD tests. Due to the analytical focus on the isotope label the chemical speciation of the so-called non-extractable residues (NER) in soils and sediments often remains unknown. These NER may stem from parent compounds, ...

Abstract:
... 2,4-Dichlorophenoxyacetic acid (2,4-D) is the third most applied pesticide in Brazil to control broadleaf weeds in crop cultivation and pastures. Due to 2,4-D’s high mobility and long half-life under anoxic conditions, this herbicide has high probability for groundwater contamination. Bioremediation is an attractive solution for 2,4-D contaminated anoxic environments, but there is limited understa ...

The presence of 3.92 g 2-propanol l-1 in both cases inhibited growth. However, acetone accumulation following 2-propanol depletion suggested that 2-propanol was co-metabolized via the acetone metabolic pathway. Glucose at 10 g l-1 increased 2-propanol ...
