journal.pone.0184652.g001PhD Student Ana Hranilovic has published her work on the yeast Lachancea thermotolerans (formerly Kluyveromyces thermotolerans) as a species with remarkable, yet underexplored, biotechnological potential. To gain an insight into L. thermotolerans population diversity and structure, 172 isolates sourced from diverse habitats worldwide were analysed using a set of 14 microsatellite markers.

The resultant clustering revealed that the evolution of L. thermotolerans has been driven by the geography and ecological niche of the isolation sources. Isolates originating from anthropic environments, in particular grapes and wine, were genetically close, thus suggesting domestication events within the species.Altogether, this study sheds light on the genotypic and phenotypic diversity of L. thermotolerans, contributing to a better understanding of the population structure, ecology and evolution of this non-Saccharomyces yeast. You can find the article online here.

ARC TW-IWP dr Renata Ristic has published her work on the impact of bottle aging on smoke tainted wine. The study aimed to investigate the stability of smoke taint in bottled wine, by determining changes in chemical composition and sensory properties of smoke affected wine after 5 or 6 years in bottle. Changes were seen in […]
