Abstract
An impedometric method for estimating the microbial load of ready-to-u se vegetables, either inoculated or not inoculated with antimicrobial- producing lactic acid bacteria, was investigated. The correlation (R-2 ) between total mesophilic bacteria (log cfu/g) and time to detection was 0.889. A discrepancy was observed for the impedometric measurement of low coliforms counts, particularly in samples inoculated with lact ic acid bacteria and stored at 8 degrees C for 6 days. Time to detecti on for the two groups of microorganisms was less than 11 h.
