Most bacteria are in biofilms; Water samples only collect planktonic or free-floating bacteria. Free-floating bacteria in animal drinking water are either sloughed off of the biofilm or pass through from ... >> Home > Resources > Researchers > Water Quality Bulletins > Biofilm > Detection and Enumeration of Bacteria...

In order to develop a rapid and specific detection test for bacteria in soil, we improved a method based on the polymerase chain reaction (PCR). Each step of the protocol, including direct lysis of cells, DNA purification, and PCR amplification, was optimized.

A foot-operated diluter/dispenser and a projection viewer were developed for use with a rapid bacterial counting technique employing agar droplets. The equipment allows the advantages of the technique to be properly realized and assists many conventional bacteriological tests which ... Bacteria [isolation & purification]
