Abstract
Lactose tryptone ricinoleate broth (0·3% lactose, 2% Oxoid tryptone, 0·1% Na ricinoleate; pH 7·1) was found to be as good as the currently recommended combination of lactose ricinoleate broth and tryptone water for the detection of Escherichia coli in the positive tubes of presumptive coliform counts.
