Strains, alternative identifiers (DSMZ), source of isolation and spoilage potential as determined by beer spoilage test.

TMW = Technische Mikrobiologie Weihenstephan. OD590 and pH values determined after 60 days of incubation can be found in S1 Table. Growth in test beers is indicated by + and -. IBU = international bitterness units (measure for hop content). Spoilage-groups: strong beer spoilage potential (SB)—growth in pilsner beer, middle potential (MB)—growth in lager beer, weak potential (WB)—growth in wheat beer, no potential (NB)—no growth in test beers.
