Method for rapid DNA extraction from bacterial communities of different soils

A method for indirect DNA extraction from various soils significantly differing in their physico-chemical properties has been developed. The proposed method is based on cell desorption from soil particles using a Tris-EDTA (TE) buffer supplemented with polyvinylpolypyrrolydone (PVPP) and sodium dode...

Description
Summary:A method for indirect DNA extraction from various soils significantly differing in their physico-chemical properties has been developed. The proposed method is based on cell desorption from soil particles using a Tris-EDTA (TE) buffer supplemented with polyvinylpolypyrrolydone (PVPP) and sodium dodecylsul-fate (SDS). Methods for subsequent cell lysis and purification of DNA preparations based on alkaline lysis followed by chromatography on ion-exchange resins were described by us earlier. The purity of the DNA preparations obtained did not depend on the type of soil. It was shown that the DNA preparations can be used for the amplification of rather large fragments, e.g., sequences spanning the complete 16S rRNA gene.
