Lipase Addition Promoted the Growth of Proteus and the Formation of Volatile Compounds in Suanzhayu, a Traditional Fermented Fish Product

Foods, 2021
This work investigated the effect of lipase addition on a Chinese traditional fermented fish product, Suanzhayu. The accumulation of lactic acid and the decrease of pH during the fermentation were mainly caused by the metabolism of Lactobacillus.

Direct conversion of methane to formaldehyde and CO on B2O3 catalysts

Nature Communications, 2020
Partial oxidation of methane to value-added C1 products remains challenging due to the favorable formation of fully-oxidized CO2. Here, the authors show supported B2O3 catalysts with tri-coordinated BO3 units as the active site are highly selective in ...

Design and Synthesis of Highly Active Antimycobacterial Mutual Esters of 2-(2-Isonicotinoylhydrazineylidene)propanoic Acid

Pharmaceuticals, 2021
The combination of two active scaffolds into one molecule represents a proven approach in drug design to overcome microbial drug resistance. We designed and synthesized more lipophilic esters of 2-(2-isonicotinoylhydrazineylidene)propanoic acid, obtained

Polyphenol alkyl ester inhibits membrane cholesterol domain formation through an antioxidant mechanism based, in nonlinear fashion, on chain length [PDF]

, 2017
Under conditions of oxidative stress, cholesterol aggregates into discrete membrane bilayer domains that precipitate the formation of extracellular crystals, a hallmark feature of the advanced atheroma in cardiovascular disease.

Study of the volatile fraction of distillates with added donkey thistle (Onopordum acanthium L.) extracts [PDF]

Journal of Central European Agriculture, 2021
ethanol extracts of donkey thistle (Onopordum acanthium L.) was conducted. The extracts were added to the pure distillate from the grapes of Melnik-55 grapevine variety in amounts of 20, 50, 80, 100, 200, 400 and 600 ml. The remaining amount to liter was

Highly Diastereo- and Enantioselective Allylboration of Aldehydes using alpha-Substituted Allyl/Crotyl Pinacol Boronic Esters via in Situ Generated Borinic Esters [PDF]

, 2013
Readily available, alpha-substituted allyl/crotyl pinacol boronic esters often give low E/Z selectivity (with Z favored) in reactions with aldehydes. We found that addition of nBuLi to the pinacol boronic ester followed by trapping of the alkoxide with ...
