Inhibition of Staphylococcus aureus Growth in Laboratory Media of Water Activity Adjusted with Polyethylene Glycols
Present work studied the growth behavior at 30°C of Staphylococcus aureus strains ATCC 6538 P, C‐243 and S‐6 in laboratory media with water activity (aw) adjusted by addition of polyethylene glycol 200 (PEG‐200) or polyethylene glycol‐400 (PEG‐400). No growth of strains ATCC 6538 P and S‐6 was obser...
