Abstract:

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 observed in any of the polyethylene glycols (PEG‐200 or PEG‐400) at or below aw about 0.93. Strain C‐243, however, showed slow growth in PEG‐400 at aw= 0.93 although was inhibited at aw= 0.92; in the case of PEG‐200 growth inhibition of this strain was observed at aw= 0.93. All strains showed good growth (either in PEG‐200 or PEG‐400) at aw= 0.96. The results confirm that PEG‐200 and PEG‐400 have a bactericidal effect on S. aureus cells that cannot be solely explained in terms of lowering of aw. Copyright © 1984, Wiley Blackwell.
