Variation of nutritional requirements of Leuconostoc oenos by organic acids

open access: yesOENO One, 1993
Leuconostoc oenos strains: m, L2 ST, X2L, have been isolated from different Argentinian red wines. Amino acids, vitamins and base requirements were determined in a synthetic medium containing L-malic acid, citric acid or both organic acids. The organisms

Effect of organic acids on the growth of Leuconostoc oenos and Lactobacillus hilgardii strains isolated from red wines

open access: yesOENO One, 1991
The effect of organic acids on the growth of Leuconostoc oenos and Lactobacillus hilgardii strains was investigated, and the interaction between organic acids, ethanol and inoculum level was determined.

Qualitative and quantitative study of interaction between Saccharomyces cerevisiae and Leuconostoc oenos

open access: yesOENO One, 1996
Weak malolactic fermentations in wine making are often attributed to the medium constituents such as ethanol and SO2. However, some authors report that the interactions between Saccharomyces cerevisiae and Leuconostoc oenos could be responsible too.

Indução da fermentação maloláctica em vinho Gewürztraminer Induction of malolactic fermentation in Gewürztraminer wine

open access: yesCiência Rural, 1997
Fermentação maloláctica é o processo metabólico de degradação do ácido L-málico em ácido L-láctico e CO2. É responsável pela redução da acidez total, além de contribuir para a estabilidade biológica e modificação de flavor nos vinhos.

Indução da fermentação maloláctica em vinho tinto com a cultura láctica viniflora oenos Induction of malolactic fermentation in red wine with the starter culture viniflora oenos

open access: yesCiência Rural, 1997
A fermentação maloláctica é responsável pela redução da acidez total, muitas vezes elevada em vinhos tintos jovens, ao mesmo tempo que proporciona maior estabilidade biológica e complexidade de aroma e sabor. No Estado do Rio Grande do Sul, a fermentação

Scientific Opinion on the update of the list of QPS‐recommended biological agents intentionally added to food or feed as notified to EFSA

open access: yesEFSA Journal, Volume 15, Issue 3, March 2017., 2017
Abstract EFSA is requested to assess the safety of a broad range of biological agents in the context of notification for market authorisation as sources of food and feed additives, food enzymes and plant protection products. The qualified presumption of safety (QPS) assessment was developed to provide a harmonised generic pre‐assessment to support ...

Etude de la lyse de Leuconostoc oenos

open access: yesOENO One, 1990
La lyse de Leuconostoc oenos a été étudiée en suspension dans l'eau et dans une solution synthétique (pH 3,5; alcool 11 % v/v, acide tartrique 4 g/l). Elle a été mesurée par deux méthodes basées sur la libération de constituants cellulaires (mesure à 210

Saccharomyces cerevisiae Mixed Culture of Blackberry (Rubus ulmifolius L.) Juice: Synergism in the Aroma Compounds Production

open access: yesThe Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
Blackberry (Rubus sp.) juice was fermented using four different strains of Saccharomyces cerevisiae (Vitilevure‐CM4457, Enoferm‐T306, ICV‐K1, and Greroche Rhona‐L3574) recognized because of their use in the wine industry. A medium alcoholic graduation spirit (<6 °GL) with potential to be produced at an industrial scale was obtained.
