Formation du butanol-2 par les bactéries lactiques isolées du vin
OENO One, 1976 Le butanol-2, présent dans les eaux-de-vie de vin de qualité médiocre, est dosé par chromatographie en phase gazeuse. Cet alcool pourrait provenir de la dégradation du butanediol-2,3 par les bactéries lactiques dans les lies de vin.
