<i>Brettanomyces bruxellensis</i> Strains Display Variable Resistance to Cycloheximide: Consequences on the Monitoring of Wine.

ABSTRACT: Brettanomyces bruxellensis is a yeast that causes spoilage in red wines due to its ability to produce volatile phenols, compounds associated with major sensory defects. Specific monitoring of low populations of this species in complex ecosystems such as wine during fermentation or aging often relies on plating onto selective media supplemented with cycloheximide. However, the variability of B. bruxellensis sensitivity to this antibiotic needs to be better characterized. A collection of 175 B. bruxellensis strains was, thus, grown on YPD medium supplemented with increasing concentrations of cycloheximide (0 to 0.5 g.L^-1), and yeast development was monitored for 20 days by image analysis. This study revealed significant inter-strain variability, with some stra
