Following initial range-finding experiments, total count determinations were used to determine minimal water activity (aW) levels for the growth and survival of Listeria monocytogenes (L.m.) and L. innocua (L.i.). Media containing three different humectants; NaCl, sucrose or glycerol were used to determine minimal aW levels for growth in the above media which were 0.92, 0.92 and 0.90 respectively. The growth minima for L.i. were similar, or slightly higher than for L.m. in these media. Survival… CONTINUE READING
