Genome Sequence of Megasphaera cerevisiae NSB1, a Bacterium Isolated from a Canning Line and Able To Grow in Beer with High Alcohol Content.

The genome sequence of the brewery isolate Megasphaera cerevisiae NSB1 was determined. Strain NSB1 tolerates 5% (vol/vol) alcohol, which is higher than previously reported for M. cerevisiae The NSB1 genome will help elucidate genetics required for alcohol tolerance and niche adaptation of this Gram-negative beer-spoilage bacterium.
