Journal ArticleDOI
Enzyme Immobilization on Inorganic Surfaces for Membrane Reactor Applications: Mass Transfer Challenges, Enzyme Leakage and Reuse of Materials
Sigyn Björk Sigurdardóttir,Jonas Lehmann,Simona Ovtar,Jean-Claude Grivel,Michela Della Negra,Andreas Kaiser,Manuel Pinelo +6 more
TL;DR: In this article, the authors present a review on enzyme immobilization focusing on the three fundamental aspects to consider when dealing with the topic: catalytic properties, enzyme leakage and reusability.
Journal ArticleDOI
Efficient ionic liquid-based platform for multi-enzymatic conversion of carbon dioxide to methanol
Zhibo Zhang,Jan Muschiol,Yuhong Huang,Sigyn Björk Sigurdardóttir,Nicolas von Solms,Anders Egede Daugaard,Jiang Wei,Jianquan Luo,Bao-Hua Xu,Suojiang Zhang,Manuel Pinelo +10 more
TL;DR: In this paper, four selected ionic liquids with high CO2 solubility were separately added to the multi-enzyme reaction mixture and the yields were compared to the pure aqueous system (control).
Journal ArticleDOI
Energy barriers to anion transport in polyelectrolyte multilayer nanofiltration membranes: Role of intra-pore diffusion
Sigyn Björk Sigurdardóttir,Sigyn Björk Sigurdardóttir,Ryan M. DuChanois,Razi Epsztein,Razi Epsztein,Manuel Pinelo,Menachem Elimelech +6 more
TL;DR: In this article, the relative contribution of intra-pore diffusion and partitioning into nanofiltration (NF) membrane pores to the apparent energy barriers for ion transport in NF membranes was investigated.
Journal ArticleDOI
Alcohol dehydrogenase on inorganic powders: Zeta potential and particle agglomeration as main factors determining activity during immobilization
Sigyn Björk Sigurdardóttir,Jonas Lehmann,Jean-Claude Grivel,Wenjing Zhang,Andreas Kaiser,Manuel Pinelo +5 more
TL;DR: The results from this study show the advantages and limitations of using nanoparticles as immobilization supports, and highlight which properties of nanoparticles must be considered to ensure an efficient immobilization.
Journal ArticleDOI
Separation of xylose and glucose using an integrated membrane system for enzymatic cofactor regeneration and downstream purification
Sofie Thage Morthensen,Sigyn Björk Sigurdardóttir,Anne S. Meyer,Henning Jørgensen,Manuel Pinelo +4 more
TL;DR: Value-added products were obtained in the reactor via enzymatic cofactor-dependent catalysis of glucose to gluconic acid and pyruvate to lactic acid, respectively, and the initial cofactor (NADH) concentration could be decreased to 10% of the stoichiometric value.
