Use of directed evolution to generate multiple-stress tolerant Oenococcus oeni for enhanced malolactic fermentation
This study aimed to optimise Oenococcus oeni for more efficient malolactic fermentation in wine with multiple stressors. First, a previously evolved ethanol tolerant strain, A90, was characterised for resistance to combined pH and ethanol stress in both MRSAJ and Red Fermented Chemically Defined …

Molecular and biochemical characterisation of esterases from oenococcus oeni and their potential for application in wine.
… EstB28 and EstCOo8 esterase proteins from O. oeni alongside EstC34, an esterase from Lactobacillus hillgardii. With a view to applying these esterases to wine, enzyme function under frequently encountered harsh physicochemical conditions in wine was examined. EstB28, EstCOo8 and EstC34 showed …

The effects of post-fermentation and post-bottling heat treatment on Cabernet Sauvignon (V. vinifera L.) glycosides and quantification of glycosidase activities in selected strains of Brettanomyces bruxellensis and Oenococcus oeni
… yeast and nine strains of lactic acid bacteria (Oenococcus oeni). All Brettanomyces strains and seven Oenococcus strains exhibited enzymatic activity. B. bruxellensis b-glucosidase activity was primarily intracellular; O. oeni showed some extracellular activity. Yeasts and bacteria showing …

Characterisation of glycosidase enzymes of wine lactic acid bacteria
… of Lactic Acid Bacteria (LAB) (22 of which being Oenococcus oeni and the remaining 18 equally represented by Lactobacillus and Pediococcus), as a start to investigating their potential application in winemaking. Three lines of research were followed in this study: a) a biochemical investigation of …

Investigation of bacteria associated with Australian wine grapes using cultural and molecular methods
… affect the growth of Saccharomyces cerevisiae or Oenococcus oeni in liquid culture. B. thuringiensis inhibited the growth of several spoilage and mycotoxigenic fungi found on grapes. Curtobacterium flaccumfaciens was the second most prevalent species detected on wine grapes. Its populations rarely …

Advances in the knowledge of lactic acid bacteria and management of wine associated microbiota using emerging technologies
… de especies de bacterias lácticas y de cepas de Oenococcus oeni, observándose en esta región un ecosistema diverso y maduro, donde tanto las especies como las cepas se fueron sucediendo como resultado de la adaptación a las condiciones de cada año, de cada bodega y de cada etapa de la …

Estudio del aire como vía de diseminación de microorganismos enológicos
… maloláctica, comparando asimismo los clones de Oenococcus oeni presentes en el aire y en los vinos. Por último, en el tercer artículo se presentan los resultados del estudio realizado sobre la presencia y evolución de los microorganismos de interés enológico en las uvas y en el aire del viñedo …

Vesículas extracelulares de microorganismos enológicos
… vesículas extracelulares de la bacteria láctica Oenococcus oeni. Posteriormente, se ha comparado la respuesta transcriptómica de S. cerevisiae a células o vesículas extracelulares de la levadura Metschnikowia pulcherrima y se ha identificado la tipicidad de las respuestas transcriptómicas de S. …

Precursors to the potent odorant wine lactone.
… when fermenting with the lactic acid bacteria Oenococcus oeni (strain VP-41) and even less of the glucose ester was converted to menthiafolic acid when fermenting with spoilage yeast Dekkera bruxellensis (strain AWRI 1499). Menthiafolic acid was not observed in a concentration above the limit …
