Published: November 2022

Continuous-flow simplified electrochemically mediated atom transfer radical polymerization (seATRP) was achieved for the first time without supporting electrolytes (self-supported) using a novel sonicated tubular microreactor. Polymerizations of different acrylic monomers were carried out under different applied currents. The reaction was fast with 75% conversion achieved at ambient temperature in less than 27 minutes. Results also showed good evolution of molecular weight and maintained narrow molecular weight distribution. The reaction rate can be further manipulated by tuning the applied current. Sonication under proper conditions was found to be able to significantly improve both reaction rate and controllability. Self-supported reactions also enable more environmentally friendly and cost-effective operations.

Biosurfactants are biodegradable, non-toxic, and environmentally beneficial substances that are produced by microorganisms. Due to their chemical characteristics and stability in various environmental circumstances, biosurfactants are low-molecular-weight, surface-active molecules of great industrial importance. The choice of the producer microbe, kind of substrate, and purification technique determine the chemistry of a biosurfactant and its production cost.

Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) has become a robust tool for analyzing a variety of biomacromolecules. However, the strong background interference produced by conventional organic matrices hinders the detection of small molecule analytes, which restricts the widespread application of MALDI-MS in metabolomics studies. Consequently, developing new organic matrices is urgently needed to overcome these issues.

A novel glucomannan, named ATSW-1, was obtained from Allii Tuberosi Semen by ion and gel permeation chromatography purification. Its structure was characterized using high-performance chromatography, Fourier transform infrared spectroscopy, gas chromatography-mass spectrometry, and nuclear magnetic resonance spectroscopy. The in vitro immune activities of ATSW-1 were examined using the Cell Counting Kit-8, the neutral red phagocytosis assay, and the secretion of related cytokines.

The combined application of dissimilatory iron-reducing bacteria (DIRB) and Fe(III) nanoparticles has garnered widespread interest in the contaminants transformation and removal. The efficiency of this composite system relies on the extracellular electron transfer (EET) process between DIRB and Fe(III) nanoparticles. While modifications to Fe(III) nanoparticles have demonstrated improvements in EET, enhancing DIRB activity also shows potential for further EET enhancement, meriting further investigation.

An α-l-Rhamnosidase gene with an open reading frame of 3192 bp encoding a 1036-amino acid protein (EhRha) was cloned from Emiliania huxleyi for flavonoid hydrolysis on the cell surface of Pichia pastoris (P. pastoris) strain GS115 by fusing with the anchor protein (AGα1) from Saccharomyces cerevisiae. Fluorescence microscopy and flow cytometry assays revealed that EhRha was successfully displayed on the cell surface of P.
