The remaining curd was divided into 10-gram aliquots,
vacuum-packed at 95% of nitrogen, and sampled after 14 days
of ripening at 4 °C. Each 10-gram curd sample was homogenized in
90 mL of sterile 20 g/L sodium citrate solution pre-warmed to 45 °C,
using a stomacher (Seward Stomacher 400 Circulator; London England).
Dilutions ranging from 100 to 10−5 were made in phage buffer
