Abstract

Wild yeasts were isolated from process surfaces of two breweries. In total, 41 strains were obtained and differentiated by cultivation on CuSO4 or crystal violet containing selective media, by fatty acid profiling and by a restriction analysis of the region spanning the internal transcribed spacers (ITS1 and ITS2) and the 5.8S rRNA gene. The restriction analysis showed the highest differentiating capacity and resulted in eleven groups. These groups were identified by the API ID 32 C kit or by sequencing the D1/D2 region of the 26S rRNA gene. Most of the wild yeasts were identified as Saccharomyces cerevisiae (46% of all isolates) and Candidapelliculosa (anamorph: Pichia anomala) (24%). No obvious differences were detected between the two breweries. While all of the S. cerevisiae isolates were able to grow in beer, only six out of 10 C. pelliculosa strains were able to tolerate this substrate. However, most of the C. pelliculosa strains showed biofilm formation in a microplate assay, but none of the S. cerevisiae isolates. Therefore, it is assumed that the former species is involved in attachment and primary biofilm formation on beer bottling plants, while S. cerevisiae is a late colonizer of a preformed biofilm but increased the beer spoiling potential of the biofilm.
