Enhancing acid tolerance of Leuconostoc mesenteroides with glutathione

Biotechnology Letters, 2011
Leuconostoc mesenteroides is a commercially important lactic acid bacterium currently used as a starter for kimchi and kefir. However, its sensitivity to acid stress limits its performance. L. mesenteroides was grown in a medium supplemented with 3.2 or 6.4 mM glutathione (GSH), and cell survival rates were measured during a long-term mild acid ...

Leuconostoc mesenteroides subsp. mesenteroides FR52 synthesizes two distinct bacteriocins

Letters in Applied Microbiology, 1996
Mesenterocin 52, a bacteriocin produced by Leuconostoc mesenteroides subsp. mesenteroides FR52, was purified from producing cells by the adsorption-desorption method, combined with reverse-phase high-performance liquid chromatography. The elution profile revealed the presence of two inhibitory peaks of activity, each displaying different inhibitory ...

Influence of Lactose-Citrate Co-metabolism on the Differences of Growth and Energetics in Leuconostoc lactis, Leuconostoc mesenteroides ssp.mesenteroides and Leuconostoc mesenteroides ssp.cremoris

Systematic and Applied Microbiology, 1999
The biodiversity of growth and energetics in Leuconostoc sp. has been studied in MRS lactose medium with and without citrate. On lactose alone, Ln. lactis has a growth rate double that of Ln. cremoris and Ln. mesenteroides. The pH is a more critical parameter for Ln. mesenteroides than for Ln. lactis or Ln.

A D-Lactic Dehydrogenase from Leuconostoc mesenteroides

Nature, 1961
THE properties of the L-lactic dehydrogenases (L-LDH) from muscle1–3 and yeast4–6 have been studied extensively. Recently, the presence of lactic dehydrogenases was reported in animal tissues7, yeast8–10 and bacteria11–13, specific for the D-isomer of lactic acid.

Pentose phosphate cleavage by Leuconostoc mesenteroides

Biochimica et Biophysica Acta, 1958
Abstract An enzyme preparation has been obtained from Leuconostoc mesenteroides which catalyzes the phosphorolytic cleavage of pentose phosphate to yield acetyl phosphate and triose phosphate. Pentose phosphates are cleaved only after conversion to xylulose 5-phosphate. A scheme describing glucose fermentation by Leuconostoc mesenteroides is also

Peptide utilization by Lactococcus lactis and Leuconostoc mesenteroides

Letters in Applied Microbiology, 2001
To explain the competition for nitrogenous nutrients observed in mixed strain cultures of Lactococcus lactis and Leuconostoc mesenteroides, the utilization of peptides as a source of essential amino acids for growth in a chemically defined medium was compared in 12 strains of dairy origin.

Determination of glucansucrase encoding gene in Leuconostoc mesenteroides

International Journal of Biological Macromolecules, 2019
A glucansucrase encoding gene was cloned into pET-28a(+) vector and expression in Escherichia coli BL21(DE3). An about 160 kDa recombinant glucansucrase was purified with a yield of 50.73% and a 4.02-fold increase in activity. The 1464 amino acid residue enzyme belongs to the GH70 subfamily and shares 90% similarity with Leuconostoc sp.

PURIFICATION AND PROPERTIES OF THE 2-KETOGLUCONOKINASE OF LEUCONOSTOC MESENTEROIDES

Canadian Journal of Microbiology, 1959
A specific and adaptive 2-keto-D-gluconokinase has been isolated from cells of Leuconostoc mesenteroides grown on 2-keto-D-gluconate. The enzyme, purified 138-fold, has an optimum pH of 7.7, is most stable between pH 6.0 and 8.0, and is quickly inactivated at temperatures above 40 °C. Magnesium chloride is required for activity.

Reclassification of Leuconostoc mesenteroides P.60 as a Pediococcus

Nature, 1959
FOR some time it has been known that the organism widely used for the assay of amino-acids and called Leuconostoc mesenteroides P.60 is not in fact a Leuconostoc. McCleskey1 examinedP.60 and suggested that it might be Streptococcus equinus. However, the culture was atypical mainly because it produced ammonia and carbon dioxide from peptone.
