Leuconostoc mesenteroides Growth Kinetics
Bacterial profile modification (BPM) is being developed as an oil recovery technique that uses bacteria to selectively plug oil depleted zones within a reservoir to divert displacing fluids (typically water) into oilrich zones. Leuconostoc mesenteroides, which produces dextran when supplied with sucrose, is a bacterium that is technically feasible for use in profile modification. However, the t...
متن کامل6-Phosphogluconate dehydrogenase from leuconostoc mesenteroides.
The pathways for degradation of 6-phosphogluconate have been rather clearly defined for several organisms, the most notable of which are yeast (Horecker, 1953), Escherichia coli (Cohen, 1951), Pseudomonas saccharophila (Entner and Doudoroff, 1952; MacGee and Doudoroff, 1954), and Pseudomonas fluorescens (Kovachevich and Wood, 1954). The enzymes from yeast and E. coli appear to be similar, if no...
متن کاملGlucose-6-phosphate dehydrogenase from Leuconostoc mesenteroides.
Glucose 6-phosphate dehydrogenase from Zeuconostoc mesenteroides, previously isolated in crystalline form (Olive, C., and Levy, H. R., Biochemistry, 6, 730 (1967)), is shown to be essentially homogeneous by disc gel electrophoresis and sedimentation velocity analysis. The weight average molecular weight is 103,700, determined by both high speed and low speed sedimentation equilibrium techniques...
متن کاملN-Acetylation of glucosamine-6-phosphate in Leuconostoc mesenteroides.
A partially purified enzyme (120-fold) from Leuconostoc mesenteroides catalyzed the reversible N-acetylation of d-glucosamine-6-phosphate. Coenzyme A was not required and inhibited the reaction rate. Neither d-glucosamine nor N-acetyl-d-glucosamine served as a substrate for the reversible reaction. The enzyme preparation retained 50% of its original activity after 5 min at 100 C. The K(m) for a...
متن کاملA glucose-6-phosphate dehydrogenase in Leuconostoc mesenteroides.
Glucose fermentation by Leuconostoc me8enteroides has been shown to proceed via a mechanism which differs from the classical Embden-Meyerhof glycolytic scheme. DeMoss, Bard, and Gunsalus (1951) found no evidence in cell-free extracts of this organism for the key enzyme aldolae but showed that cellular suspensions ferment glucose to equimolar quantities of ethanol, C02, and lactate as obligatory...
