Biofouling in industrial water systems is normally prevented by the use of bactericides. However, bactericide programmes often fail owing to the lack of suitable techniques for determining the in situ bactericide concentration ...

Current limitations in culture-based methods have lead to a reliance on culture- independent approaches, based principally on the comparative analysis of primary semantides such as ribosomal gene sequences. DNA can be ...

A 4-hydroxyphenylacetic acid (4-HPA) hydroxylase-encoding gene, on a 2.7-kb genomic DNA fragment, was cloned from the thermophile Geobacillus sp. PA-9. The Geobacillus sp. PA-9 4-HPA hydroxylase gene, designated hpaH, ...

Escherichia coli is widely considered to not survive for extended periods outside the intestines of warm-blooded animals; however, recent studies demonstrated that E. coli strains maintain populations in soil and water ...

Bactericides were applied to experimental open recirculating cooling-water systems at concentrations found to be effective under laboratory pure-culture conditions. Total aerobic plate counts and bacterial population ...

BACKGROUND: Bacterial biofilms are predominant in natural ecosystems and constitute a public health threat because of their outstanding resistance to antibacterial treatments and especially to antibiotics. To date, ...

Eighteen dominant isolates from water-cooling systems were exposed to 50mg/l of commercially available bactericides, and the kill percentage was determined after 6 h. Application costs of all bactericides giving an average ...

Controlled-release Nitrogen Fertilizers (CRNFs) are an effective fertilization technique by minimizing nutrient loss and making Nitrogen (N) available to plants as they grow. Biochar-based CRNF (BCRNF) technologies have ...

The quantity of grass-root exudates varies by season, suggesting temporal shifts in soil microbial community composition and activity across a growing season. We hypothesized that bacterial community and nitrogen ...

The phylogeny of nitrogenase has only been analyzed using the structural proteins NifHDK. As nifHDKENB has been established as the minimum number of genes necessary for in silico prediction of diazotrophy, we present an ...
