Vineyard in the Barossa Valley

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.

dave and renata in us croppedA/Prof David Jeffery and Dr Renata Ristic presented at the ‘From Fermentation to Fume Hood: the Chemistry of Wine’ Symposium, at the 254th American Chemical Society National Meeting & Exposition, held in Washington, DC, 20-24 August 2017. The ACS meetings are the largest international chemistry conferences, and routinely host more than 10,000 attendees and over 1,000 exhibitors.

The Division of Agricultural and Food Chemistry sessions of relevance to our research were almost fully booked and had an excellent array of presenters. We had the opportunity to present our research to an audience of around 65 attendees in a session with world-renowned scientists including A. Waterhouse, USA (co-author of a wine chemistry textbook with David, which was on sale at the exhibition); V. Cheynier, France; F. Mattivi, Italy; U. Fisher, Germany; R. Schneider, France, and many more (including collaborators from Australia).
