Description
Molecular biological techniques such as DNA/RNA extraction and purification, and especially the polymerase chain reaction, PCR, are rapidly gaining interest also in related fields, such as microbiology or environmental sciences. They offer new approaches and opportunities for the determination of microbial cells, DNA and RNA from soils, roots, rhizospheres, sediments and aquatic environments.
Detailed protocols for these applications are described in this manual.
