Has antibacterial activity against L.monocytogenes. Antimicrobial activity was completely lost after treatment with proteinase k, or high concentrations of chymotrypsin, trypsin or pepsin (PubMed:29064056). Also inhibited by isopropanol, methanol, acetonitrile and chloroform (PubMed:29064056). There was no significant loss of activity with either lipase, peroxidase, or amylase (PubMed:29064056). Optimum pH is about 6. Activity decreases sharply with increasing alkalinity. Optimum temperature is 30 degrees Celsius. Active from 30 to 100 degrees Celsius.
