Studies

The reconstruction of the metabolic networks is done by sequence comparison with already annotated genomes of L. lactis, L. plantarum, B. subtilis and E. coli

The two lactic acid bacteria L. lactis and S. pyogenes were studied with respect to the concentration of intracellular metabolites involved in glycolysis in time upon a glucose pulse. Models that describe this behavior are also constructed

Lactic acid bacteria generally use homolactic fermentation for generation of ATP. Here we studied the role of the lactate dehydrogenase enzyme on the general physiology of the three lactic acid bacteria Lactococcus lactis, Enterococcus faecalis and Streptococcus pyogenes. Surprisingly deletion of the ldh genes hardly affected the growth rate in chemically defined medium, however growth rate was affected in rich medium. Furthermore, deletion of ldh affected the ability for utilization of various ...

The Lactate dehydrogenases (LDH) are key metabolic enzymes in lactic acid bacteria (LAB). The LDH ( E.C. 1.1.1.27) catalyzes the reaction of pyruvate and NADH into lactate and NAD+.We have carried out an experimental and computational study of the effects of fructose-1,6-bisphosphate (FBP), phosphate (Pi) and ionic strength (NaCl concentration) on 3 LDHs from 3 LABs studied at pH 6 and pH 7.
