Dr. Krista Sumby is a Postdoctoral Research Fellow, in the ARC Training Centre for Innovative Wine Production, at the University of Adelaide. Dr. Sumby is part of the Wine Microbiology and Biotechnology group where she undertakes research into defining and exploiting the indigenous microflora of grapes for winemaking potential. Her current research is largely linked to three objectives: 1) identification of novel yeast and lactic acid bacteria (for use as pure cultures) and investigation of vine and grape attributes that favour particular species. 2) Evaluation of how bacteria interact with their environment and yeast in high stress environments such as seen in winemaking. 3) Employing this knowledge to produce superior strains and wine process outcomes. Dr. Sumby has been awarded various awards, including The Dean's Commendation for Doctoral Thesis Excellence (2013), The Harold Woolhouse Prize for The Best PhD Thesis in The Faculty of Sciences (2013) and the Postgraduate Alumni University Medal (2014).

I am currently a Postdoctoral Research Fellow, in the ARC Training Centre for Innovative Wine Production, at the University of Adelaide. My background is in microbiology and more recently microbiology and genetics of wine yeast and lactic acid bacteria (LAB). I am part of the Wine Microbiology and Biotechnology group undertaking research into yeast and lactic acid bacteria (LAB) both at a fundamental level and in the context of winemaking. 

Current project:

  • Defining and exploiting the indigenous microflora of grapes
  • Directed evolution of more robust non-Saccharomyces yeast strains for completion of alcoholic fermentation
  • Directed evolution of superior LAB for quicker and more reliable malolactic fermentation

Past projects:

  • Directed evolution of yeast and lactic acid bacteria "Wine Australia funded project"
  • Characterisation of esterase's from lactic acid bacteria and their potential for use in winemaking

Projects involving supervision of HDR students include:

  • Isolation and characterisation of improved LAB strains for optimised malolactic fermentation performance
  • Isolation and characterisation of yeast with novel biotechnological properties for use in winemaking
  • Identification and understanding of Saccharomyces and Oenococcus oeni interactions, in co-inoculated fermentations, for development of robust inoculation pairs in wine production
