Beta-galactosidases from a psychrotolerant Arthrobacter isolates and their potential use
PublicationEnzymes from extremophiles, especially psychrophiles and psychrotolerant microorganisms are currently intensively studied because of their unusual structural and functional properties. One of these enzymes is a cold-adapted - galactosidase (EC 3.2.1.23) which catalyzes the hydrolysis of - 1,4-glycosidic bonds in -galactosides. The most common - galactoside is lactose, a disaccharide which makes up 2-7% of milk. The majority of...

Reaction of aniline with ammonium persulphate and concentrated hydrochloric acid: Experimental and DFT studies
PublicationIn this paper, the reaction of aniline with ammonium persulphate and concentrated HCl was studied. As a result of our experimental studies, 2,4,6-trichlorophenylamine was identified as the main product. This shows that a high concentration of HCl does not favour oxidative polymerisation of phenylamine, even though the ammonium persulphate/HCl system is widely used in polyaniline synthesis. On the basis of the experimental data...
