To explain the competition for nitrogenous nutrients observed in mixed strain cultures of Lactococcus lactis and Leuconostoc mesenteroides, the utilization of peptides as a source of essential amino acids for growth in a chemically defined medium was compared in 12 strains of dairy origin. Both species were multiple amino acid auxotrophs and harboured a large set of intracellular peptidases. Lactococcus lactis can use a wide variety of peptides up to 13 amino acid residues whereas Leuc. mesenteroides assimilated only shorter peptides containing up to seven amino acids. Growth was limited by the transport of peptides and not by their hydrolysis. The nutritional value of peptides varied with the strains and the composition of the peptides, L. lactis being advantaged over Leuc. mesenteroides.
