Here we examined the response of Salmonella enterica serovar Typhimurium 4/74 to NaCl, KCl, and glycerol at three time points, using a constant water activity level, compared with the response of a control inoculum.
Water activity of the bread crust and crumb was determined using an AquaLab water activity meter (AquaLab, 3TE, Decagon, USA).
A water activity meter (Novasina IC-500, AW-LAB, Swaszerland) was used to measure water activity using the manufacturer's specifications.
If you will be doing any activity involving water, use a water resistant band-aid so it doesn't come off.
Finally, using reported water activity values of aqueous DMSO solutions at pH 7.4 [43], we could compare the degree of heme solubility and the amount of βH produced.
Swimmers and those performing intense physical activity should use a water-resistant or very water-resistant sunscreen.
Water activity for untreated and treated OPF juice samples was tested using water activity meter (FA-st Lab, California) operated at 28°C and 1 atm.
For the successful process of SSF, different factors like microorganisms, solid support used, water activity, temperature, aeration, and type of fermenter used should be considered before going to start any fermentation process.
Xylose and sucrose, which fulfil these criteria, are nonfermentable by P. acnes and have been used to reduce water activity and hence bacterial colonisation of wounds.
