CitI, a transcription factor involved in regulation of citrate metabolism in lactic acid bacteria.
A large variety of lactic acid bacteria (LAB) can utilize citrate under fermentative conditions. Although much information concerning the metabolic pathways leading to citrate utilization by LAB has been gathered, the mechanisms regulating these pathways are obscure. In Weissella paramesenteroides (formerly called Leuconostoc paramesenteroides), transcription of the citMDEFCGRP citrate operon a...
متن کاملAcetaldehyde metabolism by wine lactic acid bacteria.
Acetaldehyde is a volatile flavor compound present in many fermented foods and is important in the production of red and white wines. Nine strains of the genera Lactobacillus and Oenococcus were able to metabolize acetaldehyde in a resting cell system, whereas two Pediococcus strains were not. Acetic acid and ethanol were produced from its degradation. A Lactobacillus and an Oenococcus were abl...
متن کاملNitrogen metabolism in lactic acid bacteria from fruits: a review
Lactic acid bacteria (LAB) are fastidious microorganisms that require an exogenous source of amino acids or peptides, which are provided by the proteolysis of the proteins present in raw material. Generally nitrogenous compounds concentration in fruits and their derivate products are poor. Strains of Oenococcus oeni from wine show a proteolytic system that provides amino acids that are used for...
متن کاملRole of inorganic carbon in lactic acid bacteria metabolism
Capnophiles are bacteria stimulated by bicarbonate and CO2, the two major forms of inorganic carbon (IC) in physiological neutral liquids. Capnophiles are often pathogenic heterotrophs found in IC-rich ecological niches such as human cavities. Like capnophiles, the growth of lactic acid bacteria (LAB) such as Lactobacillus plantarum and Enterococcus faecalis is stimulated by IC. CO2 or HC are s...
متن کاملTransport and metabolism of vitamin B6 in lactic acid bacteria.
Streptococcus faecalis 8043 concentrates extracellular [3H]pyridoxal or [3H]pyridoxamine primarily as the corresponding 5'-phosphates. Accumulation of pyridoxamine requires an exogenous energy source and is inhibited by glycolysis inhibitors. A membrane potential is not required for transport of pyridoxamine, and an artificially generated potential does not drive uptake in this organism. Based ...
