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...
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 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 کاملThe determination of proline in protein hydrolysates with Lactobacillus brevis.
Proline was first determined in 1901 by Fischer (2), who isolated copper Land nn-proline dihydrates from an ester fraction of an acid hydrolysate of casein. During the ensuing three decades proline was determined essentially by this procedure in the hydrolysates of more than 50 proteins by Fischer (1901-ll), Abderhalden (1902-36), Osborne (1906-ll), and other workers. That data of satisfactory ...
متن کاملRelaxed control of sugar utilization in Lactobacillus brevis.
Prioritization of sugar consumption is a common theme in bacterial growth and a problem for complete utilization of five and six carbon sugars derived from lignocellulose. Growth studies show that Lactobacillus brevis simultaneously consumes numerous carbon sources and appears to lack normal hierarchical control of carbohydrate utilization. Analysis of several independent L. brevis isolates ind...
