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