Exoprotease activity of Leuconostoc oenos in stress conditions [PDF]

Journal of Applied Microbiology, 1998
Exoprotease activity during 48 h of total energy and nutrient starvation was examined in Leuconostoc oenos X 2 L isolated from wine. Starved cells after 2 h of incubation at 30°C in citrate buffer, 0.05 mmol 1 -1 pH 5, showed greater extracellular proteolytic activity than at the onset of starvation.

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

Ciência 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.

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

EFSA 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 ...

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

The 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.

Application of Response Surface Methodology for Optimizing Arginine Deiminase Production Medium for Enterococcus faecium sp. GR7

The Scientific World Journal, Volume 2013, Issue 1, 2013., 2013
Arginine metabolism in Enterococcus faecium sp. GR7 was enhanced via arginine deiminase pathway. Process parameters including fermentation media and environmental conditions were optimized using independent experiments and response surface methodology (central composite design).

Purification and characterization of 2-oxoglutarate decarboxylase of Leuconostoc oenos [PDF]

Journal of General Microbiology, 1990
Summary: 2-Oxoglutarate decarboxylase from the lactic acid bacterium Leuconostoc oenos was purified by precipitation with PEG and ion-exchange chromatography. The strictly thiamin-pyrophosphate-dependent enzyme decarboxylated 2-oxoglutarate to succinic semialdehyde. Oxalacetate was metabolized to a lesser extent.
