TL;DR: A sensitive and reliable method to quantify SCFAs by liquid chromatography tandem mass spectrometry (LC–MS/MS) in multiple reaction monitoring (MRM) mode is developed and suggested that this highly sensitive method would be useful for quantifyingSCFAs extracted from stool in an aqueous solution to monitor gut health.

TL;DR: In this article, a ceramic ultrafiltration membrane was used to recycle distillery wastes in a batch ethanol fermentation process, and almost the same ethanol yield was obtained up to eight recycles and a slight increase in the fermentation by-products was observed.

TL;DR: This study used mass spectrometry-guided bioinformatic analysis of genomic sequences to identify an NRP-type secondary metabolite from Streptomyces peucetius ATCC 27952 and revealed that the functional siderophore peptide produced by this cluster had a molecular weight of 644.4 Da.

TL;DR: A robust and highly sensitive mass-assisted laser desorption/ionization mass spectrometry (MALDI-MS)-based quantitative platform to identify the absolute quantities of endogenous estrones in a variety of clinical specimens is developed and may be a general method for the targeted metabolomics of ketone-containing metabolites, which can reflect clinical conditions and pathogenic mechanisms.

TL;DR: It is suggested that addition of both HP and polar aprotic solvent in the reaction mixture is a powerful alternative to enhance production of polyphenolic chemicals rather than screening appropriate organic solvents for whole-cell catalysis ofpolyphenols.
