^*Mean values of counts. Minor and major values count. Detection limit: 1 × 10² CFU/g. Maximum recommended level: 1 × 10⁴ CFU/g [26]. DRBC: dichloran rose bengal chloranphenicol. DG18: dichloran glycerol 18%. Letters in common are not significantly different according to Fisher’s protected LSD test (𝑃<0.05).
