Plasmids Oenococcus oeni

Other more or less vital functions are determined by plasmids. These small, circular DNA molecules are completely independent of the chromosome. They vary in size and number depending on the species and strain of bacteria. In Oenococcus oeni, plasmids of 2 to 40 kb are often identified and one of them has been sequenced (Fremaux et al, 1994). So far, no function of enological or physiological interest has been attributed to them. In general, the plasmids determine functions such as the fermentation of certain sugars, the hydrolysis of proteins, resistance to phages, antibiotics, heavy metals, etc.
