Periodate-oxidized starch (oxystarch) was shown to be a good substitute for formaldehyde or glutaraldehyde as hardening agents in an immobilization procedure of microbial cells within gelatin. In fact, contrary to both aldehydes, oxystarch has no antimicrobial activity so that the immobilized cells retain their viability. Cell loading and mechanical stability of the immobilizates make them suitable for operations in continuous bioreactors.

Abstract
Periodate-oxidized starch (oxystarch) was shown to be a good substitute for formaldehyde or glutaraldehyde as hardening agents in an immobilization procedure of microbial cells within gelatin. In fact, contrary to both aldehydes, oxystarch has no antimicrobial activity so that the immobilized cells retain their viability. Cell loading and mechanical stability of the immobilizates make them suitable for operations in continuous bioreactors.File in questo prodotto:
