Pyruvate 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...

1,3-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...

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...

Evaluation of Probiotic Yoghurt Produced by Lactobacillus paracasei ssp. tolerans

The objectives of this paper were production of probiotic yoghurt using L. paracasei ssp. tolerans, and evaluation of pH changes, viable counts, and organoleptic properties of the produced yoghurt. It was observed that the pH decrease during the fermentation period was faster in the milk inoculated with L. paracasei ssp. tolerans plus starter culture. There was a gradual decrease in pH in both ...
