New insights into cinnamoyl esterase activity of Oenococcus oeni
Collombel, Ingrid; Melkonian, Chrats; Molenaar, Douwe; Campos, Francisco M.; Hogg, TimSome strains of Oenococcus oeni possess cinnamoyl esterase activity that can be relevant in the malolactic stage of wine production liberating hydroxycinnamic acids that are precursors of volatile phenols responsible for sensory faults. The objective of this study was to better understand the basis of the differential activity between strains. After initial screening, five commercial strains of O. oeni were sel...
Changes in the composition of the lactic acid bacteria behavior and the diversi...
Collombel, Ingrid; Campos, Francisco M.; Hogg, TimPhenolic compounds are important components of wine and are known to have an impact on the physiology of wine microbes. The influence of specific sub-sets of phenolic compounds on the growth and metabolism of lactic acid bacteria (LAB) and on the diversity of Oenococcus oeni in inoculated and non-inoculated red wines was investigated during malolactic fermentation (MLF) and subsequent storage. Representative O....
