Abstract |
The primary objective of this study is to evaluate chemical preservatives which can be added to the sample bottle before collection which will be effective in stabilizing the coliform density for not less than 48 hours using current methodology for detecting coliform organisms. This study evaluates the stability of control samples stored at 22 C and 4 C which are compared to each other and to the stability of test samples which contained different preservatives and preservative concentrations. Candidate preservations were chosen based upon their reported stabilizing effect in foods, bacteriological holding medium and as stabilizing agents used to prepare quality control performance samples. |
