Adaptation to high salt in Lactobacillus: Role of peptides and proteolytic enzymes

Aims: To study the influence of peptides and proteolytic enzymes in the osmotic adaptation of Lactobacillus casei. Methods and Results: Di- and tri-peptides added individually increased the osmotolerance of Lact. casei when grown in a chemically defined medium (CDM) containing NaCl. Growth stimulati...
