LeChevallier, Mark W.
RESUMO
Verification of membrane filter total coliform colonies from drinking water was increased 87% by testing for the presence of β-galactosidase and cytochrome oxidase, compared with verification by determination of gas production in lauryl tryptose broth. Over 90% of the coliforms verified by testing for β-galactosidase and cytochrome oxidase were representative of the typical coliform genera.
