Stabilized 5-Hydroxymethylfurfural Oxidase and Kinetics-Guided Feeding Mitigate Substrate Inhibition in Resting-Cell 2,5-Furandicarboxylic Acid Production

Abstract HMFO enables O2-dependent conversion of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) without soluble cofactor regeneration, but prolonged operation is limited by HMF substrate inhibition, pH drift, and enzyme deactivation. Here, these limitations we...

Physics-Guided Hybrid Intelligent Method for Predicting Mixed Oil Length in Multiproduct Pipelines

Abstract To ensure the reasonableness of the contamination oil cutting plan as well as to improve product quality and operation efficiency, accurately predicting the length of mixed oil in pipelines is crucial. However, due to the high-dimensional nonlinear characteristics in mix...
