Effect of linolenic acid concentration on conjugated linoleic acid production by Butyrivibrio fibrisolvens A38

Article Abstract:

Research on Butyrivibrio fibrisolvens show that the organism did not produce significant amounts of conjugated linoleic acid (CLA) until the concentration of linoleic acid was high enough to inhibit biohydrogenation, inhibit growth, and cause cell lysis. This could indicate that CLA production is not a normal end product but an artifact in cells that cannot biohydrogenate.

A role for fructose 1,6-diphosphate in the ATPase-mediated energy-spilling reaction of Streptococcus bovis

Article Abstract:

Fructose 1,6-diphosphate (FDP) from cells of Streptococcus bovis activate lactate dehydrogenase that leads to energy spilling. FDP activates membrane-bound ATPase of S. bovis and produces a 5-fold decrease in the K(sub m) for ATP. Energy-spilling occurs only when the production of lactate is high. The utilization of ammonia helps in lactate production and ATP-spilling since amino acid elimination, leaving ammonia as the sole nitrogen source, leads to lactate dehydrogenase production.

Relationship between intracellular phosphate, proton motive force, and rate of nongrowth energy dissipation (energy spilling) in Streptococcus bovis JB1

Article Abstract:

Proton motive force ((delta)p) and the energy spilling rate are apparently responsive to fluctuations in the intracellular inorganic phosphate (P(sub i)) concentration. This was concluded from the results of experiments designed to determine the effect of glucose availability and amino nitrogen on intracellular fructose-1,6-diphosphate (FDP) and phosphate concentrations, ATP hydrolysis and (delta)p. FDP increased, intracellular P(sub i) decreased and energy spilling rate increased when the rate of glucose addition to S. bovis cell suspensions was increased.
