Bioethanol fermentation kinetic studies are described with effective aspects of, but not limited to, substrate limitation, oxygen limitation, substrate inhibition, product inhibition, and cell death. The majority of these studies have used Saccharomyces cerevisiae and regular mathematical modelling in the form of unstructured unsegregated kinetic modelling. In this paper, the bioethanol fermentation kinetics of pentoses or hexoses or their combination are reviewed. The modes of culture (e.g., batch and continuous), microorganisms used, process conditions, and equations including various effective aspects are discussed. The kinetic models giving the best fit to the experimental data were proposed by the Ghaly and EL‐Taweel as well as Hjersted and Henson. The results showed better agreement between modelling and experiment on using simpler equations which consider the three important effective aspects: substrate limitation, substrate inhibition and product inhibition when grown in the standard growth medium. However, more complex equations show a better fit when the optimum temperature is unclear, co‐culturing is employed, or when growth conditions deviate from standard media and process conditions.

葡萄糖,木糖或其组合发酵生物乙醇的数学模型-综述

描述了生物乙醇发酵动力学研究,其有效方面包括但不限于底物限制,氧限制,底物抑制,产物抑制和细胞死亡。这些研究大多数都使用了酿酒酵母以及以非结构化非分离动力学建模形式进行的常规数学建模。本文综述了戊糖或己糖或其组合的生物乙醇发酵动力学。讨论了培养模式(例如分批和连续培养),使用的微生物,工艺条件以及包括各种有效方面的方程式。Ghaly和EL-Taweel以及Hjersted和Henson提出了最适合实验数据的动力学模型。结果表明,在建模和实验之间使用更简单的方程式(在三个标准的有效条件下)的更好的一致性:底物限制,底物抑制和在标准生长培养基中生长时的产物抑制。但是,当不清楚最佳温度时,更复杂的方程式会显示出更好的拟合度,
