title: Effect of ultrasound stimulation on metabolic modulation of pyruvic acid.
abstract: Pyruvic acid lay on the center position of Eremothecium ashbyii metabolic fluxes, during fermentation, a high performance liquid chromatography (HPLC) method is presented for the simultaneous determination of pyruvic acid in the Eremothecium ashbyii cell culture of both with ultrasound stimulation and the control. Dry weight and riboflavin are also mentored. The results of this study show that the ultrasound stimulation can give rise to pyruvic acid change, at the same time; change of pyruvic acid concentration is correlative to that of dry weight of mycelium and content of riboflavin.
