The yeasts of a Mâconnais winery
The yeast populations of the various parts of a Mâconnais winery have been analysed from a taxonomy and biology point of view. 14 species have been isolated from the cernent vats used for red and white wine making, on the horizontal wine-presses with wooden and plastics laths, on the walls and ground of the winery and on the bottling apparatus. The qualitative and quantitative distribution of the species has been studied. The dominant species was Saccharomyces cerevisiae. Hansenula anomala and Pichia membranaefaciens were also frequent. Some species have newly been revealed in this habitat: Hansenula subpelliculosa, Saccharomyces pretoriensis, Cryptococcus infirmo-miniatus, Cr. laurentii and Aureobasidium pullulans.
