Parameters for induction ofbacteria to grow in beer were as described by Haakensen et al. (2007).
In brief, assessment of bacterial isolate growth in beer required
adaptation of the bacteria using modified mMRS broth supplemented
with incremental concentrations of beer. Identities of the isolates were
confirmed pre- and post-growth in beer by sequencing the 16S rRNA
gene (Haakensen et al., 2007).
