Abstract:The current study was undertaken to immobilize Kluveromyces lactis β-galactosidase on alginate coated magnesium oxide nanoparticles (ACMONPs). Transmission electron microscopy showed that MgO-NPs synthesized by wet chemical approach were of 27 nm size and spherical in shape. Excellent biocompatibility of sodium alginate resulted in 90% immobilization yield for β-galactosidase due to covalent attachment. Soluble and immobilized β-galactosidase exhibited its pH and temperature-optima at pH 7.0 and at 40 oC, resp… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
