9 mL peptone water (0.1%), followed by successive dilutions
and pour plating.To assess the viability of the microorganisms from both yoghurt
and Prato cheese after 1 day of manufacture, 25 g sample were
transferred to stomacher bags with 225 mL sodium citrate
(2%) pH 7.0 for homogenization (5 min at medium speed).Then,
serial dilutions were made in peptone water (0.1%), and the aliquots
were pour-plated in the culture media described in Section 2.3. The
complete experiment was repeated three times
