Protease production by Leuconostoc oenos strains isolated from wine

World Journal of Microbiology and Biotechnology, 1993
Two separate, extracellular proteolytic activities were demonstrated in four strains of Leuconostoc oenos isolated from Argentinian wines. The first took place in the early growth phase and the other had its maximum at the end of growth. The two proteolytic enzymes had different pH and temperature optima.

Continuous cider fermentation with co-immobilized yeast and Leuconostoc oenos cells

Enzyme and Microbial Technology, 2000
Ca-alginate matrix was used to co-immobilize Saccharomyces bayanus and Leuconostoc oenos in one integrated biocatalytic system in order to perform simultaneously alcoholic and malo-lactic fermentation of apple juice to produce cider, in a continuous packed bed bioreactor.

CIDER PRODUCTION WITH IMMOBILIZEDLEUCONOSTOC OENOS [PDF]

Journal of the Institute of Brewing, 1998
Cider obtained with Saccharomyces earevlaiae and immobilized Leuconoatoc oenos attained the desired attenuation without residual sugars. Decarboxyiation off L-malic to L-lactic acid by heteroiactic bacteria and the formation off secondary products in ...

Plasmids in Leuconostoc oenos

Plasmid, 1987
A new procedure was used to isolate 11 plasmids from eight Leuconostoc oenos strains. Plasmid DNA was not detected in 34 other strains of this species. Plasmid sizes ranged from 2.47 to 4.61 kilobase pairs. This is the first report of extrachromosomal elements in L. oenos.

Stimulation of the growth of leuconostoc oenos by tomato juice

Archiv f�r Mikrobiologie, 1967
Tomato juice contains a growth factor (TJF) active for some strains of Leuconostoc oenos but not required by other lactic acid bacteria. TJF does not appear to be identical with any known growth factor, is of limited distribution in natural products and is destroyed by the growth of most strains of Leuconostoc oenos and by Lactobacillus plantarum and ...

Histidine decarboxylase activity of Leuconostoc oenos 9204

Food Microbiology, 1995
Some bacteria are able to produce histamine from histidine via an enzyme: histidine decarboxylase (HDC). This biogenic amine may be responsible for vasomotor and digestive disturbances. In food such as fish meat or fermented products such as sauerkraut, cheese, fermented sausages and wines, bacteria can produce histamine.

Response of Leuconostoc œnos to environmental changes

Journal of Applied Microbiology, 1996
Malolactic fermentation, a spontaneous step in vinification, is frequently controlled by use of malolactic bacterial starters of Leuconostoc œnos. Strains isolated from fermenting wines and then submitted to industrial processes to obtain freeze‐dried preparations lose their natural ...

Recognition of Leuconostoc oenos strains by the use of DNA restriction profiles

Applied Microbiology and Biotechnology, 1993
The chromosome of 41 Leuconostoc oenos strains obtained from collections in different countries was analysed with the aim of differentiating the strains. Pulsed field electrophoresis (TAFE) was used to separate large DNA fragments created by the restriction enzymes NotI, SfiI and ApaI, which specifically recognize guanines or cytosines. The genomic DNA

A selective medium for the isolation of malolactic mutants of Leuconostoc oenos

Letters in Applied Microbiology, 1994
We have developed a selective medium for the isolation of Leuconostoc oenos mutants defective in malolactic fermentation. Forty per cent of colonies isolated directly on selective plates after UV mutagenesis had lost their ability to degrade malate.
