Oligopeptide assimilation and transport by Oenococcus oeni

Aims:  Oenococcus oeni is a slow‐growing wine bacterium with a low growth yield. It thrives better on complex nitrogen sources than on free amino‐acid medium. We aimed to characterize the oligopeptide use of this micro‐organism. Methods and Results:  Several peptides of two to eight amino‐acid resid...

Description
Summary:Aims:  Oenococcus oeni is a slow‐growing wine bacterium with a low growth yield. It thrives better on complex nitrogen sources than on free amino‐acid medium. We aimed to characterize the oligopeptide use of this micro‐organism. Methods and Results:  Several peptides of two to eight amino‐acid residues were able to provide essential amino acids. The disappearance of various peptides from extracellular medium was assessed with whole cells. Initial rates of utilization varied with the peptide, and free amino acids were released into the medium. Conclusions:  Oenococcus oeni was able to transport the oligopeptides with two to five amino‐acid residues tested and to hydrolyse them further. Significance and Impact of the Study:  This study has clear implications for the relationship between wine nitrogen composition and the ability of O. oeni to cope with its environment.
