The influence of water activity (adjusted with three humectants: sodium chloride, glycerol and polyethylene glycol) on the growth of three strains of Aeromonas hydrophila at 28, 10 and 3.8°C was studied. Minimum water activity for growth (MWAG) of Aer. hydrophila varied with strain, temperature and type of humectant. MWAG ranged from 0.940 to 0.973 (28°C), 0.959 to 0.980 (10°C) and 0.975 to 0.980 (3.8°C).
