ABSTRACT Growth inhibition of Lactococcus lactis provoked by increasing osmolarity is reversed when glycine betaine (GB) or its analogs are added to a defined medium. Lacticin 481 production increased sharply with growth medium osmolarity in the absence of osmoprotectant but remained unaffected when GB was supplied in media of increasing osmolarity.

The cross-inhibition between 23 Lactococcus lactis subsp. lactis strains and 9 L. lactis subsp. cremoris strains with different randomly amplified polymorphic DNA patterns, all isolated from the same ecological niche—cheese made in the spring at a single factory from raw milk without added lactic starter cultures—was investigated. Cross-inhibition, as determined by the agar well diffusion assay, was recorded in 130 cases (12.7%) out of 1,024 total cases, with 109 cases due to supernatants of L. lactis subsp. lactis strains and 21 cases due to supernatants of L. lactis subsp. cremoris strains. L. lactis strains isolated in April, May, and June showed differences in their inhibitory activities, with cross-inhibition against each other in 34.7, 14.1, and 6.1% of the cases, respectively. Polymerase chain reaction techniques using specific primers for nisin, lacticin 481, and lactococcin A only revealed the presence of the structural gene of lacticin 481 in two L. lactis subsp. lactis strains.
