Verification of membrane filter total coliform colonies from drinking water was increased 87% by testing for the presence of beta-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 beta-galactosidase and cytochrome oxidase were representative of the typical coliform genera. (Copyright (c) 1983, American Society for Microbiology.)
