Correlation parameters between the counts of lactic acid bacteria from salami samples obtained by Petrifilm™AC associated with MRS broth and supplemented with chlorophenol red (incubated in anaerobiosis, protocol 2) after different incubation times (24, 48 and 72 h) comparedwith two conventional plating protocols: MRS at pH 5.7 (protocol 5) and MRS supplemented with chlorophenol red (protocol 3).
