New Findings from Tsinghua University in the Area of Chemical Engineering Described (Method for Regulating Oscillatory Dynamic Behavior in a Zymomonas mobiliz Continuous Fermentation Process)

By a News Reporter-Staff News Editor at Journal of Engineering -- Research findings on Chemical Engineering are discussed in a new report. According to news reporting out of Beijing, People's Republic of China, by VerticalNews editors, research stated, "Periodically oscillating concentrations of product, biomass, and substrate have been observed in a continuous fermentations process with Zymomonas mobiliz both in experiments and simulations."

Our news journalists obtained a quote from the research from Tsinghua University, "This paper describes the characteristics of oscillatory phenomena based on Hopf bifurcation analysis and proposes a method to regulate the oscillatory dynamic behavior. In this method, these dynamic behaviors of oscillations in concentrations of product, biomass, and substrate were simulated, the relationship between amplitude/period and operational condition was modeled."

According to the news editors, the research concluded: "This model could be used as a guide to adjust the operating conditions to attenuate unfavorable oscillations and mitigate corresponding operability problems when the oscillation itself is unavoidable."
