Molecular Insights into the Rhamnolipid-Promoted Enzymatic Performance on Removing Phenolic Pollutants.

Horseradish peroxidase (HRP) is a metalloenzyme widely used in various biochemical applications but is susceptible to activity loss and instability under suboptimal conditions. In this study, rhamnolipid (RL) was, for the first time, employed as an additive to enhance the catalytic performance of HRP, including in a dual-enzyme cascade system with glucose oxidase (GOx). We carried out catalytic experiments on phenol degradation and showed that protecting HRP from deactivation is critical in maintaining the high catalytic effect in the dual-enzyme cascade.

Effects of high stocking density on the growth performance, intestinal health and bile salts composition of broiler chickens.

Introduction: The intestinal dysfunction plays an important role in the decreased growth performance of broiler chickens under high stocking density. Gut microbiota plays an important role in maintaining intestinal health. However, the modulation pathway of gut microbiota by regulating the intestinal barrier and histomorphology remains unknown.

Constructing an Interlaced Catalytic Surface via Fluorine-Doped Bimetallic Oxides for Oxygen Electrode Processes in Li-O Batteries.

Lithium-oxygen (Li-O) batteries, renowned for their high theoretical energy density, have garnered significant interest as prime candidates for future electric device development. However, their actual capacity is often unsatisfactory due to the passivation of active sites by solid-phase discharge products. Optimizing the growth and storage of these products is a crucial step in advancing Li-O batteries.

Supermolecule Cucurbituril Subnanoporous Carbon Supercapacitor (SCSCS).

It is quite challenging to prepare subnanometer porous materials from traditional porous precursors, and use of supramolecules as carbon sources was seldom reported due to the complex preparation and purification processes. We explore a facile one-pot method to fabricate supramolecular coordination compounds as carbon sources. The resultant CB[6]-derived carbons (CBC) have a high N content of 7.

[Effects of different intensities exercise combined with resveratrol on RBP4 in aged obese rats].

Objective: To investigate the effects of different intensity exercise combined with resveratrol on retinol binding protein 4(RBP4) mRNA and protein expression in visceral adipose tissue and plasma RBP4 concentration of aged obese rats.

Methods: Eighty male SD rats aged 3 weeks were randomly divided into the control group and the experimental group. Rats of the control group(C) were fed with ordinary feed of 6% fat (=12).
