The investigated byocatalyst consists of gelatin entrapped cells of Saccharomyces cerevisiae retaining invertase activity.Comparative examination of pH profile, apparent Km saturation velocity and activation energy indicates that thee entrapment procedures did not influence invertase affinity with sucrose but lead to some of activity probably due to either enzyme inactivation or cell wall impairment as well as substrate diffusion limitation in the gel matrix.

Abstract
The investigated byocatalyst consists of gelatin entrapped cells of Saccharomyces cerevisiae retaining invertase activity.Comparative examination of pH profile, apparent Km saturation velocity and activation energy indicates that thee entrapment procedures did not influence invertase affinity with sucrose but lead to some of activity probably due to either enzyme inactivation or cell wall impairment as well as substrate diffusion limitation in the gel matrix.File in questo prodotto:
