Effect of Aeration on Organic Acid Production by Propionibacterium shermanii
Propionibacteria have been reported as being oxygen sensitive bacteria. Nevertheless, in this work, we intend to show that Propionibacterium shermanii CDB 10014 is able to grow even at high volumetric oxygen transfer coefficients (KLa). Similar final cell concentrations were achieved in experiments at different KLa values, with increasing cell yield from 0.08 g/g cells in anaerobic con ditions...
متن کاملAdenosylcobalamin-dependent methylmalonyl-CoA mutase from Propionibacterium shermanii. Active holoenzyme produced from Escherichia coli.
The linked structural genes coding for both subunits of adenosylcobalamin-dependent methylmalonyl-CoA mutase from the Gram-positive bacterium Propionibacterium shermanii have been altered by site-directed mutagenesis and placed under the control of an inducible phage-T7-specific plasmid promoter in Escherichia coli. Conditions have been found under which both alpha- and beta-subunits are produc...
متن کاملSteady state and exchange kinetics of pyruvate, phosphate dikinase from Propionibacterium shermanii.
Evidence is presented based on requirements for exchange in the partial reactions, initial velocity and exchange kinetics and product inhibition, that the pyruvate, phosphate dikinase reaction of propionibacteria occurs by a nonclassical Tri Uni Uni Ping Pong mechanism. The mechanism involves a pyrophosphoryl enzyme, a phosphoryl enzyme, and the free enzyme, and three functionally distinct and ...
متن کاملIsolation and characterization of a pyrophosphate-dependent phosphofructokinase from Propionibacterium shermanii.
A pyrophosphate-dependent phosphofructokinase (pyrophosphate; D-fructose-6-phosphate-1-phosphotransferase) has been purified and characterized from extracts of Propionibacterium shermanii. The enzyme catalyzes the transfer of phosphate from pyrophosphate to fructose 6-phosphate to yield fructose-1,6-P2 and phosphate. This unique enzymatic activity was observed initially in Entamoeba histolytica...
متن کاملProperties of Alanine Dehydrogenase and Aspartase from Propionibacterium freudenreichii subsp. shermanii.
During lactate fermentation by Propionibacterium freudenreichii subsp. shermanii ATCC 9614, the only amino acid metabolized was aspartate. After lactate exhaustion, alanine was one of the two amino acids to be metabolized. For every 3 mol of alanine metabolized, 2 mol of propionate, 1 mol each of acetate and CO(2), and 3 mol of ammonia were formed. The specific activity of alanine dehydrogenase...
