Excuse me, I have 2 questions about the answers you have just posted:
1. Could Listeria monocytogenes really grow under pH=4.0 condition ?
A: Probably not, so note changes in the last reply
2. As Listeria monocytogenes is gram +ve, should I believe that it could grow under as low as 0.85 water activity condition?(I took this information from your lecture notes...)
A: 0.85 Aw is too low for L. monocytogenes to grow.
Thank you in advance =]
