Aliquots (100 μl)
were plated in duplicate on non-selective and selective/differential
solid media: total aerobic mesophilic bacterial counts were determined
on Plate Count agar with Milk (1%) (PCA-M) (VWR International) after
incubation at 32 °C for 48 h; lactic acid bacteria (LAB) countswere made
on de Man, Rogosa and Sharpe agar (MRSA) (VWR International) after
incubation at 32 °C for 48 h; Baird–Parker agar (BPA) (VWR International)
was used to enumerate staphylococci and micrococci after incubation
at 37 °C for 48 h; and enterobacteria were counted on Violet Red
Bile Glucose agar (VRBGA) (VWR International) after incubation at
37 °C for 24 h
