The lifestyle of beer spoiling lactic acid bacteria (LAB) was focused, investigating their genomic properties, metabolism and physiology. We found that, on one hand, beer-spoiling LAB are characterized by mostly species-specific, chromosomally encoded metabolic settings conferring adaptation to the niche beer. On the other hand, strains of different species share a dynamic mobile genetic pool, encoding additional traits beyond hop tolerance, which finally enable and facilitate LAB growth in beer. The respective genes can be used as targets for quality control.
