Antibiotics are used in animal livestock production for therapeutic treatment of disease and
at subtherapeutic levels for growth promotion and improvement of feed efficiency. It is …

Agricultural and industrial practices more than doubled the intrinsic rate of terrestrial N fixation
over the past century with drastic consequences, including increased atmospheric nitrous …

Pure bacterial cultures were isolated from a highly enriched denitrifying consortium previously
shown to anaerobically biodegrade naphthalene. The isolates were screened for the …

To understand the phylogeny and taxonomy of eight new toluene-degrading denitrifying
isolates, we performed a 16S rRNA sequence analysis and a gas chromatographic analysis of …

Dissimilatory nitrate reduction to ammonium (DNRA) and denitrification are contrasting
microbial processes in the terrestrial nitrogen (N) cycle, in that the former promotes N retention …

Reduction of seed-bank persistence is an important goal for weed management systems.
Recent interest in more biological-based weed management strategies has led to closer …

The dynamics of individual microbial populations and their gene functions in agricultural
soils, especially after major activities such as nitrogen (N) fertilization, remain elusive but are …

Biological removal of the ozonation by-product, bromate, was demonstrated in biologically
active carbon (BAC) filters. For example, with a 20-min EBCT, pH 7.5, and influent dissolved …

RNA methylase genes are common antibiotic resistance determinants for multiple drugs of
the macrolide, lincosamide, and streptogramin B (MLS B ) families. We used molecular …

DNA-based stable isotope probing (SIP) is a novel technique for the identification of organisms
actively assimilating isotopically labeled compounds. Herein, we define the limitations to …
