Adsorptive Properties of the Preparation Material from the Skin of Corn Stalk for Enzyme Immobilization

Abstract

In order to investigate the characterizations of skin adsorption material (SAD) prepared from skin of corn stalks by High Boiling Solvent treatment, neutral proteinase and maltogenic amylase were selected as adsorbate to assess its potential applicability for enzyme immobilization. The structure of SAD and Skin were compared by FT-IR and XRD. The characterizations of the adsorption of the different enzymes onto SAD were studied. The isotherm of the maltogenic amylase was found to be linear with the Freundlich equation, and proteinase was found to be linear with the Langmuir equation in the studied concentration range. SAD could be applied the bio-active material and Skin to prepare SAD.

Immobilization ofCandida rugosalipase by adsorption-crosslinking onto corn husk

“…Through method of adsorptioncrosslinking, an agricultural waste such as of corncobs, banana stem, rice husk, coconut fibers, and stems salak were reported as the support in immobilization lipase from acinotebacter [8]. Utilization of corn husk was studied to be used as a support on proteinase and amylase enzyme immobilization by adsorption [4]. In 2013, continue research on core utilization of corn stalks as support for the immobilization amylase, lipase and proteinase enzymes [9].…”

“…Corn husk can be used as a raw material for enzyme immobilization support because its availability is abundant, are renewable and biodegradable [4]. Some criteria of a good support is inert, physically strong, stable, can be regenerated, and able to increase and decrease the activity of enzymes inhibitors [5].…”
