Pretorius, N. published the artcileInfluence of sugars and pH on the citrate metabolism of different lactic acid bacteria strains in a synthetic wine matrix, SDS of cas: 97-67-6, the main research area is sugar citrate metabolism lactic acid bacteria strain synthetic wine; Lactobacillus plantarum ; Oenococcus oeni ; acetoin; citrate lyase; citrate metabolism; diacetyl.
This study investigated the influence of sugars (glucose and fructose) and pH on the gene expression of citE (citrate lyase β-subunit) and the subsequent formation of metabolites associated with citrate metabolism Different levels of glucose (2.5, 50 and 115 gl-1), fructose (2.5, 50 and 115 gl-1) and pH (3.0, 3.5, 4.0 and 5.0) were evaluated for their effect on citE expression in four different lactic acid bacteria strains. Two Oenococcus oeni strains and two Lactobacillus plantarum strains were used, of which one strain of each species screened pos. for the citE gene. Among the factors tested, fructose had the biggest influence on the relative expression of citE in Oenococcus oeni. In addition, the citrate-pos. strains produced high concentrations of diacetyl and acetoin. This study gives an overview of how sugar, pH and different lactic acid bacteria strains influence citE gene expression and the formation of metabolites associated with citrate metabolism closely linked to malolactic fermentation (MLF).
