Abstract

Esterases from Listeria monocytogenes strains isolated from cheeses were analyzed by starch gel electrophoresis. Five esterases, numbered from EST 1 to EST 5 in order of decreasing anodal migration, were identified. The EST 1, EST 3, EST 4, and EST 5 set was most active toward alpha-naphthyl propionate, while EST 2 was most active toward alpha-naphthyl acetate. Results from inhibitor studies suggest that all of these esterases were EC class 3.1.1.1 carboxylesterases, except that EST 1 and EST 3 also showed some sensitivity to parahydroxymercuribenzoate. Polymorphism of these five esterases was observed in the population. Twelve esterase patterns were defined and used to subdivide serotypes.
