The intraspecific genetic diversity of Oenococcus oeni, the key organism in
the malolactic fermentation of wine, has been evaluated by random amplified
polymorphic DNA (RAPD), ribotyping, small-plasmid content, and sequencing
of RAPD markers with widespread distribution among the strains. Collection
strains representing the diversity of this species have been studied
together with some new isolates, many of which were obtained from wines
produced by spontaneous malolactic fermentation. The RAPD profiles were
strain specific and discerned two main groups of strains coincident with
clusters obtained by macrorestriction typing in a previous work. Ribotyping
and the conservation of RAPD markers indicates that O. oeni is a relatively
homogeneous species. Furthermore, identical DNA sequences of some RAPD
markers among strains representative of the most divergent RAPD clusters
indicates that O. oeni is indeed a phylogenetically tight group, probably
corresponding to a single clone, or clonal line of descent, specialized to
grow in the wine environment and universally spread.
