Expression of an alkaline feruloyl esterases from thermophilic Chaetomium thermophilum and its boosting effect on delignification of pulp.

Exploration of feruloyl esterase (FAE) with the resistance to heat and alkali conditions in biobleaching process to improve the separation efficiency of lignocellulose is the key to achieving green papermaking. Herein, we expressed FAEB of C. thermophilum and obtained a thermostable alkaline FAE that can effectively promote the removal of lignin from pulp.

Boosting the anode performance of microbial fuel cells with a bacteria-derived biological iron oxide/carbon nanocomposite catalyst.

Modifying the electrodes of microbial fuel cells (MFCs) with iron oxides can improve the bacterial attachment performances and electrocatalytic activities for energy conversion, which is of significance in the fabrication of MFCs. However, the conventional modification methods usually result in the aggregation of iron sites, producing the electrodes of poor qualities. Herein, we report a novel method for the modification of electrochemical electrodes to boost the anode performance of MFC.
