Aerobic plate counts were determined by inoculating 0.1 ml of
the homogenate sample onto triplicate sterile plates of prepoured
and dried Standard Method Agar. Then, plates were
incubated for 48 h at 35 C (ISO NF- 21149, 2006). Duplicates
of each dilution (1 ml) of neutralized and non neutralized samples
were pour-plated using Standard Method Agar (Oxoid,
Basingstoke, Hampshire, England) and incubated at 30 C
for 48 h. Plates containing 25–250 colonies were counted and
the average number of CFU/g was calculated.
