Historically, biotechnology has missed up to 99% of existing microbial resources by using
traditional screening techniques. Strategies of directly cloning 'environmental …

Most of the microorganisms in nature are inaccessible as they are uncultivable in the
laboratory. Metagenomic approaches promise the accessibility of the genetic resources and …

Advances in the sequencing of DNA extracted from media such as soil and water offer huge
opportunities for biodiversity monitoring and assessment, particularly where the collection or …

There is an increased interest in the extraction of nucleic acids from various environmental
samples, since molecular techniques allow less biased access to a greater portion of …

To monitor the dissemination of resistance genes into the environment, we determined the
occurrence of tetracycline resistance (Tcr) genes in groundwater underlying two swine …

A microfluidic device has been designed, fabricated and tested for its ability to purify
bacteriophage lambda DNA and bacterial chromosomal DNA, a necessary prerequisite for …

Analysis of microbial community structure in complex environmental samples using nucleic
acid techniques requires efficient unbiased DNA extraction procedures; however, humic …

To elucidate fungal diversity in methane hydrate-bearing deep-sea marine sediments in the
South China Sea, internal transcribed spacer (ITS) regions of rRNA genes from five different …

Inhibition remains the greatest methodological challenge in molecular analysis of buried
biological remains. Inhibitory compounds associated with soil environments comprise …

Antibiotics are used at therapeutic levels to treat disease; at slightly lower levels as
prophylactics; and at low, subtherapeutic levels for growth promotion and improvement of …
