A novel cold-active β-D-galactosidase with transglycosylation activity from the Antarctic Arthrobacter sp. 32cB - gene cloning, purification and characterization
A gene encoding a novel β-D-galactosidase from the psychrotolerant Antarctic bacterium Arthrobacter sp. 32cB was isolated, cloned and expressed in Escherichia coli. The active form of recombinant β-D-galactosidase consists of two subunits with a combined molecular weight of approximately 257 kDa. The enzyme's maximum activity towards o-nitrophenyl-β-D-galactopyranoside was determined as occurring at 28 °C and pH 8.0. However, it...

Publikacja omawia wyniki badań niobanu lantanu domieszkowanego akceptorowo pod kątem właściwości elektrycznych i strukturalnych.
In this study, the potential of selected psychrotolerant yeast strains for phenol biodegradation was studied. From 39 strains isolated from soil and water samples from Rucianka peat bog, three psychrotolerant yeast strains: A011, B021 and L012 showed the ability to phenol degradation. The result shows that all three yeast strains could degrade phenol at 500 mg l-1 and 750 mg l-1 concentration, whereas strains A011 and L012 could...
