Extraction from Soil & Wastes
Small-scale DNA Sample Preparation Method for Field PCR Detection of Microbial Cells and Spores in Soil, C.R. Kuske, et. al., Appl. Environ. Microbiology, Vol.64, p.2463-2472 (1998). "Only the MiniBeadbeater was effective for DNA extraction from Bacillus globigii (B. subtilis subsp. niger) endospores or Fusarium moniliforme conidia"
Rapid Method for Coextraction of DNA and RNA from Natural Environments for Analysis of Ribosomal DNA- and rRNA-based Microbial Community Composition, R.I. Griffiths et. al., Appl. Environ. Microbiology, Vol 66, p.5488-5491(2000)
Simultaneous DNA/RNA Extraction from Soil, a protocol based on a modified method of Griffiths et. al.(2000), from Eoin Brodie, April 2003. References a Fast-Prep machine. Call for MBB equivalent speed settings.
Improved Extraction of PCR-quality Community DNA from Digesta and Fecal Samples, Zhongtang Yu and Mark Morrison, BioTechniques, Vol 36, p.808-813 (2004). Content: Beadbeating gives "1.5 to 6 fold increase in DNA yield compared to other methods.
Comparative Analysis of Fecal DNA Extraction Methods with Phylogenetic Microarray: Effective Recovery of Bacterial and Archaeal DNA using Mechnical Cell Lysis, Anne Solonen et al, J Microbiological Methods, Vol 81, p.127-134 (2010). Content: Four widely used methods are compared. The DNA yields varied up to 35 fold. A modified protocol of Yu and Morrison was the best.
Skim Milk Drastically Improves the Efficiency of DNA Extraction from Andisol, a Volcanic Ash Soil, Yuko Takada Hoshino and Naoyuki Matsumoto, Japan Agri Research Quart, Vol 39-4, 247-252 (2005) Content: 40 mg skim milk powder/gram soil sample was added as an adsorption competitor. Does not interfere with PCR procedures.
