Concentration profiles in batch fermentation of hydrolyzed lignocellulose

Experimental data was obtained for profiling changes in concentrations of two inhibiting compounds in batch fermentation of a synthesized liquor resembling hydrolyzed lignocellulose, a furan (furfural) and a phenolic compound (vanillin), along with standard fermentation data, i.e. substrate, biomass and ethanol concentrations. The initial inhibitor concentrations and fermentation temperatures in the 18 experiments were varied according to a two-level complete center composite experimental design. Based upon these observed variations in the fermentative behavior, the fermentation kinetics were modeled, as published in the corresponding article, including microbial conversion rates of the inhibitive compounds into their less toxic derivatives.本数据集采集了两类抑制性化合物在模拟水解木质纤维素（hydrolyzed lignocellulose）的合成发酵液分批发酵过程中的浓度变化数据，两类化合物分别为呋喃类化合物糠醛（furfural）与酚类化合物香兰素（vanillin）；同时还收录了配套的标准发酵参数，包括底物、生物量及乙醇浓度。本研究共开展18组实验，各组实验的初始抑制剂浓度与发酵温度均按照两水平全中心复合实验设计进行变量调控。基于观测得到的发酵行为变化特征，本研究针对发酵动力学构建了预测模型，相关研究成果已发表于对应学术论文，模型纳入了抑制性化合物向低毒性衍生物的微生物转化速率相关参数。
