DISSERTATION: DNA-based detection and characterisation of strictly anaerobic beer-spoilage bacteria

Wednesday, 16 December 2009 11:16

VTT’s Research Scientist Riikka Juvonen defended her thesis: “DNA-based detection and characterisation of strictly anaerobic beer-spoilage bacteria” on 11th December at the University of Helsinki. Routine cultivation methods for detection of strictly anaerobic bacteria in breweries are time-consuming and do not allow species identification. The main aim of Riikka’s doctoral studies was to utilise DNA-based techniques in order to improve detection and identification of the Sporomusa sub-branch beer-spoilage bacteria and to increase understanding of their biodiversity, evolution and natural sources.

This study showed that DNA-based techniques provide useful tools for obtaining more rapid and specific information about the presence and identity of the strictly anaerobic spoilage bacteria in the beer production chain than is possible using cultivation methods. This should ensure financial benefits to the industry and better product quality to customers.
