Total viable counts (TVC) were enumerated on Plate Count Agar
(PCA) (Pronadisa) with 1% NaCl according to the recommendations by
Dainty, Shaw, Boer, and Scheps (1975), and incubated at 32 °C for
48 h. Gram-positive catalase-positive cocci (GCC+) were determined
on Mannitol-Salt Agar (MSA) (Pronadisa) at 32 °C for 48 h. Lactic acid
bacteria (LAB) were plated on double layer MRS agar at pH 5.7 and
incubated at 32 °C for 48 h.
