Coliform index
The coliform index is a rating of the purity of water based on a count of fecal bacteria. It is one of many tests done to assure sufficient water quality. Coliform bacteria are microorganisms that pri...
RpoS
The gene rpoS (RNA polymerase, sigma S) encodes the sigma factor sigma-38 (σ38, or RpoS), a 37.8 kD protein in Escherichia coli. Sigma factors are proteins that regulate transcription in bacteria. Sig...
