A group-specific primer, F243 (positions 226 to 243, Escherichia coli numbering), was developed by comparison of sequences of genes encoding 16S rRNA (16S rDNA) for the detection of actinomycetes in the environment with PCR and temperature or denaturing gradient gel electrophoresis (TGGE or DGGE, respectively). The specificity of the forward primer in(More)
The effects of agricultural-improvement treatments on the chitinolytic activity and diversity of a microbial community were investigated within an upland pasture. The treatments of interest were lime and treated sewage sludge, both commonly applied to pasture land to improve fertility. Burial of chitin-containing litter bags at the field site resulted in(More)
The efficiency and reproducibility of DNA extraction from soil was tested for variations in lytic and purification treatments and their effect on yield and purity of DNA. The extraction yield was improved by increasing the concentration of EDTA or monovalent ions in isolation buffers, by the introduction of mechanical lysis treatments, and by the use of(More)
Our current understanding of Antarctic soils is derived from direct culture on selective media, biodiversity studies based on clone library construction and analysis, quantitative PCR amplification of specific gene sequences and the application of generic microarrays for microbial community analysis. Here, we investigated the biodiversity and functional(More)
The essential oil and gum of Pistacia lentiscus var. chia, commonly known as the mastic tree, are natural antimicrobial agents that have found extensive uses in medicine in recent years. In this work, the chemical composition of mastic oil and gum was studied by GC-MS, and the majority of their components was identified. alpha-Pinene, beta-myrcene,(More)
The microbial ecology of soil still presents a challenge to microbiologists attempting to establish the ways in which bacteria and fungi actively metabolise substrates, link into food webs and recycle plant and animal remains and provide essential nutrients for plants. Extraction and in situ analysis of rRNA has enabled identification of active taxa, and(More)
Annual carbon flux through soil respiration is ten times greater than fossil fuel combustion, but its component parts are poorly understood because they are the product of complex multitrophic interactions between soil organisms. A major component of carbon flux from plants to soil occurs through networks of symbiotic arbuscular mycorrhizal fungi. Here,(More)
The breakdown of chitin within an acidic upland grassland was studied. The aim was to provide a molecular characterisation of microorganisms involved in chitin degradation in the soil using soil microcosms and buried litter bags containing chitin. The investigation involved an examination of the effects of liming on the microbial communities within the soil(More)
The ever increasing microbial resistome means there is an urgent need for new antibiotics. Metagenomics is an underexploited tool in the field of drug discovery. In this study we aimed to produce a new updated assay for the discovery of biosynthetic gene clusters encoding bioactive secondary metabolites. PCR assays targeting the polyketide synthases (PKS)(More)
Product line concepts are widely used and adopted across a number of industries. Whilst the software product line concepts are readily accessible to commercial software product companies, the application within corporate environments whose core business is not software has been less evident. What are the types of challenges that large corporate(More)
