Multiple solvent signal presaturation and decoupling artifact removal in 13C{1H} nuclear magnetic resonance [PDF]
Magnetic Resonance, 2020 The analysis by proton-decoupled carbon-13 nuclear magnetic resonance spectroscopy of samples dissolved in solvents presenting strong multiple resonances can be facilitated by the suppression of these resonances by multisite presaturation.

Agricultural and Biological Chemistry, 1978 Methanol-utilizing bacteria, Klebsiella sp. No. 101 and Microcyclus eburneus could grow aerobically and statically on 1,2-propanediol. The authors examined the presence of enzyme activity of adenosyl-B12 dependent diol dehydratase as well as NAD dependent diol dehydroagenase.

Aerobic excretion of 1,2-propanediol by Salmonella typhimurium [PDF]
Journal of Bacteriology, 1988 Salmonella typhimurium excreted the rhamnose fermentation product 1,2-propanediol not only under anaerobic conditions, but also under aerobic conditions. The absence of an aldehyde dehydrogenase enzymatic activity that oxidizes to lactate the lactaldehyde formed in the dissimilation of rhamnose raised the intracellular concentration of the aldehyde ...

Dehydratase mediated 1-propanol production in metabolically engineered
Microbial Cell Factories, 2011 Background With the increasing consumption of fossil fuels, the question of meeting the global energy demand is of great importance in the near future. As an effective solution, production of higher alcohols from renewable sources by microorganisms has ...

Dissimilation of 1,2-propanediol by rumen micro-organisms [PDF]
British Journal of Nutrition, 1973 1. The main products of fermentation of 1,2-propanediol weren-propanol and propionic acid, but variable amounts of acetic acid and carbon dioxide were also formed. The concentrations of an intermediate propionaldehyde increased and then decreased.2. A tentative scheme is suggested, showing that 1,2-propanediol is first dehydrated to propionaldehyde ...

True Closed‐Loop Recyclable Hydrogels Enabled by Imine Boronic Ester Crosslinking
Advanced Materials, EarlyView.Subtle molecular differences in imine boronic ester crosslinkers profoundly influence hydrogel properties. 2‐formylphenylboronic acid crosslinkers form previously undisclosed 3‐amino‐benzoxaborole heterocycles, enhancing elasticity despite lower crosslinking density compared to their 4‐formylphenylboronic acid counterparts.

Advanced Science, EarlyView.This graphical abstract presents gut microbial cross‐feeding through a Mechanism–Technology–Application framework. It summarizes major resource‐transfer modes, the experimental and computational tools used to establish causality, and potential interventions involving dietary substrates, live biotherapeutic products, and engineered microbes.

Anais da Academia Brasileira de Ciências, 2021 Hydroxyl-terminated polybutadiene (HTPB) is widely used in the formulations of solid propellants used in rocket motors. Furthermore, in general, chain extenders and short chain diols, such as 1,4-butanediol and 1,2-propanediol, can also be used in ...
