Glucose Oxidase Immobilization on TMAH-Modified Bentonite

open access: yesIndonesian Journal of Chemistry, 2015
The influence of bentonite modification by tetramethyl ammonium hydroxide (TMAH) on its capability to immobilize glucose oxidase (GOX) was studied. Modification of bentonite was conducted by the adding of 0-5% (v/v) TMAH.
