Abstract

GONDIM, A. C. S.  and  SILVA, L. R. D. da. Effect of the glutaraldeide on the adsorption of proteic extract of the Ipomoea Batatas (L) Lam in analcime zeolite surface. Cerâmica [online]. 2005, vol.51, n.319, pp.219-224. ISSN 0366-6913.  http://dx.doi.org/10.1590/S0366-69132005000300008.

The analcime zeolite (Na16Al16Si32O96.nH2O) was treated with hydrochloric acid 0.25 mol.L-1, followed by the funcionalization with glutaraldehyde and immersed in the proteic extract obtained from gross extract of sweet potato pulp (Ipomoea Batatas (L) Lam), which presents in its composition the polyphenol oxidase enzyme (PPO). Other samples were submitted to the same procedure with characterizations by scanning electron microscopy, Fourier Transform Infrared spectroscopy and thermogravimetry.

Keywords : analcime zeolite; glutaraldehyde; polyphenol oxidase; enzyme.
