2016/10/24/ · Introduction. An estimated annual 1.3 billion dry tons of lignocellulosic biomass could support ethanol production and allow the U.S. to reduce its petroleum consumption by 30%. 1 Although plant biomass hydrolysis yields sugar mixtures rich in glucose and xylose, fermentation inhibitors are generated by the chemical pretreatment
2018/9/1/ · For an uncoupled microbial fed-batch fermentation process of glycerol bioconversion to 1,3-propanediol (1,3-PD), we establish a nonlinear switched system model with free terminal time and unknown time-delays, in which the reaction mechanism of extracellular and intracellular environment and the regulation of dha regulator are
2023/12/1/ · There are some uncertain kinetic parameters in microbial fermentation system because of the unclear intracellular metabolic mechanisms. Considering the affection of these uncertain parameters on system performance, dynamic process optimization of the fermentation system can be modeled as a distributionally robust
With the aggravation of environmental pollution and energy crisis, the sustainable microbial fermentation process of converting glycerol to 1,3-propanediol (1,3-PDO) has become an attractive alternative. However, the difficulty in the online measurement of glycerol and 1,3-PDO creates a barrier to t
