Comparison of cell surface proteinase activities within the Lactobacillus genus
Whole cells of Lactobacillus delbrueckii subsp. bulgaricus CNRZ 397 ( Lb. bulgaricus CNRZ 397) are able to hydrolyse α- and β-caseins. We have isolated a mutant of Lb. bulgaricus altered for growthExpand

A multifunction ABC transporter (Opt) contributes to diversity of peptide uptake specificity within the genus Lactococcus.
Growth of Lactococcus lactis in milk depends on the utilization of extracellular peptides. Up to now, oligopeptide uptake was thought to be due only to the ABC transporter Opp. Nevertheless, analysisExpand
