AB The extensive existing knowledge about S. cerevisiae based on studies in the lab or in human-made fermentations is unrivaled. Surprisingly almost nothing is known about the natural ecology of the yeast. Wild Saccharomyces are referred as being associated with oak trees especially the bark, which seems surprising considering the high sugar conditions in for example the wine making process. Almost all wild Saccharomyces isolates come from oak but this does not necessarily mean that this is really its primary habitat. There exists a strong bias according to focusing on this environment for sampling as well as to the isolation protocols used. Until now, the yeast / oak association could not be convincingly proved. The aim of this thesis is to shed some light on the natural ecology of Saccharomyces yeast and to specifically search for the natural environment of the yeast. For this approach a combination of field work, next-generation sequencing of the oak bark environment as well as experiments of wild Saccharomyces with naturally co-occurring microorganisms was used.
