Evaluation of Microbiological Methods of Analysis for Natural Mineral Water, Part 2: Revivable Total Colony Count—Collaborative Trial
Abstract
John Waddell (‘) and Roger Wood c)r A collaborative trial to evaluate a number of media for enumerating the reviyable total colony count SfCq at 37″C and 22’C in natural mineral waters QIIMW) was canied out. Eighteen laboratories participated in this trial. Each participant enumerated the RTCC of two independent samples comprising blind duplicates using six dffirent media. The method used was essentialLy as described in ISO 6222 : 1988, with the restrictions that d surfoce plating method was used and that the 37″C count was incubated for only 24 h.
