FIGURE 1.

Bacterial counts (log cfu/ml) in bovine raw milk samples (M1, M2, and M3) determined at the initial stage (0) and after cold storage at 6°C for 3 and 7 days (C3, C7) or in cold-stored while N₂-flushed samples for 3 and 7 days (N3, N7). The bars correspond to standard deviations. TM, “total counts” on PCA; G-, Gram-negative bacteria on Mac Conkey agar; TPr, “total counts” on protease agar; Pr+, protease-positive; TLi, “total counts” on lipase agar; Li+, lipase-positive; TPLa, “total counts” on PLase agar; PLa+, PLase-positive; TRB, “total counts” on blood agar; Hem+, α or ß types of haemolysis; Psy, psychrotrophs.
