Ketones or aldehydes containing one or more carbon-carbon double bonds and a carbonyl group conjugated with at least one double bond are hydrolyzed by the action of heat and pressure in the presence of water by a batch or continuous process. The ketone or aldehyde cleaves at the double bond ...
Gelatinization of starch prior to saccharification is not essential, and such processes were patented already in the early 1950s.1715 Inclusion of such cationic surfactants as benzyldodecyldimethylammonium chloride or tert-butyl-(2-ethoxyethyl)phenoxydimethylammonium chloride activates enzymes.1716 Saccharifi...

This protocol represents the latest innovation in the field of nanocellulose production, resulting in improved yield and reduced particle size. Nanocellulose (NC) was extracted from date seeds using 1-butyl-3-methylimidazolium chloride [Bmim]Cl coupled with a transition metal complex comprising copper ...

Although cyclic imines are present in various bioactive secondary metabolites, their degradative metabolism remains unknown. Here, we report that copper amine oxidases, which are important in metabolism of primary amines, catalyze a cyclic imine cleavage
