Pentose Fermentation by Lactobacillus Plantarum
Extracts of Lactobucillus plantarum derived from cells grown on Larabinose contain an active isomerase, which converts L-arabinose to Lribulose (1, 2), and a ribulokinase, which catalyzes the formation of L-ribulose &phosphate (3,4). Such extracts also catalyze the conversion of L-ribulose 5-phosphate to D-xylulose 5-phosphate, which has been shown to be the key intermediate in pentose fermenta...
متن کاملFermentation of glucuronic acid by Lactobacillus brevis.
Certain heterofermentative lactic acid bacteria often encountered in food and beverage fermentations are able to utilize the uronic acids as a sole carbon source for energy (J. R. Stamer and B. O. Stoyla, Bacteriol. Proc., p. 1, 1967). Although the mechanisms of uronic acid degradation by gram-negative or phytopathogenic microorganisms have been extensively studied (W. J. Payne and R. A. McRori...
متن کاملCharacterization of bacteriocin produced by Lactobacillus plantarum F1 and Lactobacillus brevis
Lactobacillus plantarum F1 and L. brevis OG1 isolated from Nigerian fermented food products, produced bacteriocins that had broad spectrum of inhibition against both pathogenic, food spoilage organisms and various lactic acid bacteria. The test organisms exhibited activities of 6400 and 3200 AU/ml respectively against Escherichia coli NCTC10418 and Enterococcus faecalis EF1, but did not inhibit...
متن کامل1,3-Propanediol:NAD+ oxidoreductases of Lactobacillus brevis and Lactobacillus buchneri.
In the cofermentation of glycerol with a sugar by Lactobacillus brevis and Lactobacillus buchneri, a 1,3-propanediol:NAD+ oxidoreductase provides an additional method of NADH disposal. The enzyme has been purified from both L. brevis B22 and L. buchneri B190 and found to have properties very similar to those reported for the enzyme from Klebsiella pneumoniae. The enzymes required Mn2+ and are p...
متن کاملMolecular cloning and functional expression in lactobacillus plantarum 80 of xylT, encoding the D-xylose-H+ symporter of Lactobacillus brevis.
A 3-kb region, located downstream of the Lactobacillus brevis xylA gene (encoding D-xylose isomerase), was cloned in Escherichia coli TG1. The sequence revealed two open reading frames which could code for the D-xylulose kinase gene (xylB) and another gene (xylT) encoding a protein of 457 amino acids with significant similarity to the D-xylose-H+ symporters of E. coli, XylE (57%), and Bacillus ...
