Description
Physicochemical features:
- incubation of laterosporulin with proteolytic enzymes (pepsin, trypsin, chymotrypsin, proteinase K, pronase E) did not show any reduction in its antimicrobial activity.
- fully heat stable as it keeps its antimicrobial activity after exposure to 120°C for 15 min.
