Fermentation 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 کاملPyruvate metabolism in Lactobacillus brevis.
The pyruvate metabolism of LactobaciUus plantarum and Latobacillus arabino8su, which according to Bergey (1948) are identical organisms, has been studied by Rowatt (1951) and Nossal (1952). Both these homofermentative lactobacilli were shown to form 3-hydroxybutan-2-one (acetoin) as the main product of their pyruvate metabolism. No one appears to have studied the metabolism of pyruvate by any o...
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 کاملGlutamate decarboxylase from Lactobacillus brevis: activation by ammonium sulfate.
In this study, the glutamate decarboxylase (GAD) gene from Lactobacillus brevis IFO12005 (Biosci. Biotechnol. Biochem., 61, 1168-1171 (1997)), was cloned and expressed. The deduced amino acid sequence showed 99.6% and 53.1% identity with GAD of L. brevis ATCC367 and L. lactis respectively. The His-tagged recombinant GAD showed an optimum pH of 4.5-5.0, and 54 kDa on SDS-PAGE. The GAD activity a...
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...
