Genetic Determinants of Industrially Important Characters in Lactococci

Genetic determinants of lactose fermentation, proteolytic activity and bacteriocin production in the strains L. lactis subsp. lactis MPL114, L. lactis subsp. cremoris MPC112 and L. lactis subsp. lactis biovar. diacetylactis MPD166 were studied. As a result of mutation and genetic transfer studies, it was determined that all of these characters were encoded by the 65.4 kb plasmid in L. lactis subsp. cremoris MPC112. Lactose fermentation and proteolytic activity were encoded by the 68.0 kb plasmid and bacteriocin production was encoded by the 12.4 kb plasmid in L. lactis subsp. lactis MPL114. Lactose fermentation, proteolytic activity and bacteriocin production in L. lactis subsp. lactis biovar. diacetylactis MPD166 strain were found to be responsible for the 61.0 kb, 14.2 and 9.0 kb plasmids respectively.
