Characterization of membrane-bound ATPase activity of Leuconostoc oenos: growth conditions

Applied Microbiology and Biotechnology, 1994
A protocol for Leuconostoc oelignos plasma membrane isolation, which was improved for studying lipidic and proteic constitution according to growth conditions, allowed us to determine some kinetic properties of membrane-bound ATPase activity: optimum pH, 5.6; the Michaelis constant (K m) for ATP, 1.1 mm; Mg2+-dependence.

Purification and properties of a malolactic enzyme from Leuconostoc oenos ATCC 23278

Journal of Basic Microbiology, 1990
AbstractThe malolactic enzyme of Leuconostoc ocnos ATCC 23278 was purified 136fold. The molecular weight was estimated at 132,000 when determined by gel filtration. The enzyme contained two identical subunits (Mw = 66,000 using sodium dodecyl sulfate gel electrophoresis). The malolactic enzyme catalyzes the NAD+‐ and Mn+‐dependent reaction L‐malate → L‐

Lysogeny of Oenococcus oeni (syn. Leuconostoc oenos ) and Study of Their Induced Bacteriophages

Current Microbiology, 1998
A large number of strains of Oenococcus oeni (formerly Leuconostoc oenos) that had been isolated from wines were checked for lysogeny with mitomycin C as inducer. As a result of this test, 45% of the strains proved to be lysogenic, suggesting that lysogeny is widespread among bacteria isolated from wines during malolactic fermentation.

Isolation and characterization of Leuconostoc oenos phages from German wines

Applied Microbiology and Biotechnology, 1992
Thirty-four wines that showed problems during malolactic fermentation were obtained from five different German wineries and were examined for the presence of phages using electron microscopy and the agar spot-test. Phages were discovered in 11 of the wines and host strains were found for ten of these phages.

Cellular fatty acid composition of Leuconostoc oenos

Journal of Applied Bacteriology, 1989
The cellular fatty acid composition of 70 lactic acid bacteria was examined by capillary gas chromatography. Fifty‐four Leuconostoc oenos strains, including three reference, type strains from the other Leuconostoc spp., nine ...

Leuconostoc oenos entrapment: Application to continuous malo-lactic fermentation

1996
The malolactic fermentation is one of the major biological steps in the organoleptic maturation of wine and cider. Classically, this fermentation takes place after the alcoholic fermentation. The medium is then quite poor with respect to the requirements for the cellular multiplication.

GENOME DIVERSITY IN SEVERAL STRAINS OF LEUCONOSTOC-OENOS FROM THE CHIANTI REGION

1995
Total DNA restriction pattern analysis was employed to study the genome diversity among several strains of lactic acid bacteria, isolated from Chianti wines and previously attributed to the species Leuconostoc oenos. A reference strain and a selected strain sold as starter culture of male-lactic fermentation were included too.
