Dye decolorization of magnetically retrievable formulation of laccase with amine-functionalized microparticles.

Laccase is an important enzyme used in many industries because of its multi-substrate catalyst. New immobilization agents are excellent tools for enhancing the abilities of this enzyme. In this study, immobilization of laccase on silica microparticles with NH (S-NH) surface modification to use in dye removal applications was aimed.

Investigation of NDM, VIM, KPC and OXA-48 genes, blue-carba and CIM in carbapenem resistant Enterobacterales isolates.

Introduction: Carbapenem resistance is an emerging problem in Enterobactarales. We aimed to investigate the presence of carbapenemase genes blaNDM, blaKPC, blaVIM and blaOXA-48 and evaluate the phenotypic blue-carba method and carbapenem inactivation method (CIM) in Enterobacterales isolates.

Methodology: Total of 153 Enterobacterales isolates were tested in the study.

Purification and cDNA cloning of a novel neurotoxic peptide (Acra3) from the scorpion Androctonus crassicauda.

Androctonus crassicauda is one of the Southeastern Anatolian scorpions of Turkey with ethno-medical and toxicological importance. Two toxic peptides (Acra1 and Acra2) were isolated and characterized from the venom of this scorpion. In this communication, the isolation of an additional toxin (Acra3) by chromatographic separations (HPLC and TSK-gel sulfopropyl) and its chemical and functional characterization is reported.
