Degradation of agricultural land and the resulting loss of soil biodiversity and productivity are of great concern. Land-use management practices can be used to ameliorate such degradation. The soil bacterial communities at three separate arable farms in eastern England, with different farm management practices, were investigated by using a polyphasic(More)
A new laccase (EC 1.10.3.2) produced by Streptomyces cyaneus CECT 3335 in liquid media containing soya flour (20 g per liter) was purified to homogeneity. The physicochemical, catalytic, and spectral characteristics of this enzyme, as well as its suitability for biobleaching of eucalyptus kraft pulps, were assessed. The purified laccase had a molecular mass(More)
The many opportunities for mitigating atmospheric carbon emissions in developing countries include reforesting degraded lands, implementing sustainable agricultural practices on existing lands and slowing tropical deforestation. This analysis shows that over the next 10 years, 48 major tropical and subtropical developing countries have the potential to(More)
The suitability of culture supernatant from Streptomyces albus ATCC 3005 for use in the biobleaching of eucalyptus kraft pulp was investigated. S. albus was found to grow on a minimal salts medium containing oat spelts xylan and yeast extract as the main carbon and nitrogen sources, respectively. Maximal extracellular xylanase and peroxidase production was(More)
The composition of the active microbial (bacterial and fungal) soil community in an arable wheat field subjected to different management practices was examined at five times during a 1-year period. Field sections were fertilized either at good agricultural practice (GAP) levels or at reduced levels (0.5x GAP) and were inoculated with vesicular arbuscular(More)
In this study, we developed a triplex real-time reverse transcription-PCR (RT-PCR)-based method that detects and distinguishes between noroviruses belonging to genogroups I, II, and III and that targets the junction between the regions of open reading frame 1 (ORF1) and ORF2. This is the first assay to include all three genogroups and the first real-time(More)
Tropical agroecosystems are subject to degradation processes such as losses in soil carbon, nutrient depletion, and reduced water holding capacity that occur rapidly resulting in a reduction in soil fertility that can be difficult to reverse. In this research, a polyphasic methodology has been used to investigate changes in microbial community structure and(More)
AIM To identify potential reservoirs and transmission routes of human pathogenic Campylobacter spp. METHODS AND RESULTS An enrichment PCR method for the detection and identification of Campylobacter jejuni and/or Campylobacter coli in faecal, food and river water samples was applied to 1450 samples of 12 matrix types obtained from a defined geographical(More)
Oil refineries are facing many challenges, including heavier crude oils, increased fuel quality standards, and a need to reduce air pollution emissions. Global society is stepping on the road to zero-sulfur fuel, with only differences in the starting point of sulfur level and rate reduction of sulfur content between different countries. Hydrodesulfurization(More)
AIMS To isolate benzene-degrading strains from neutral and alkaline groundwaters contaminated by benzene, toluene, ethylbenzene, xylenes (BTEX) from the SIReN aquifer, UK, and to test their effective pH range and ability to degrade TEX. METHODS AND RESULTS The 14 isolates studied had an optimum pH for growth of 8, and could degrade benzene to below(More)
