A simple method for fixing invertase-active whole cells of yeast (S. cerevisiae) on tuff granules by gelatin is presented. Some kinetic and operative properties of the resulting preparation have been investigated and compared with the corresponding ones of the unsupported gelatin-immobilized whole-cell invertase. Except for a difference in the activity yield, both preparations showed similar kinetic properties. From the operative point of view, the supported preparation was shown to be particularly suitable for continuous hydrolysis of sucrose in a packed bed reactor.

Abstract
A simple method for fixing invertase-active whole cells of yeast (S. cerevisiae) on tuff granules by gelatin is presented. Some kinetic and operative properties of the resulting preparation have been investigated and compared with the corresponding ones of the unsupported gelatin-immobilized whole-cell invertase. Except for a difference in the activity yield, both preparations showed similar kinetic properties. From the operative point of view, the supported preparation was shown to be particularly suitable for continuous hydrolysis of sucrose in a packed bed reactor.File in questo prodotto:
