Table 3 The effects of trehalose concentration on the activity (initial rates) of α-chymotrypsin precipitated by n-propanol in acetonitrile.

From: Optimising biocatalyst design for obtaining high transesterification activity by α-chymotrypsin in non-aqueous media

Trehalose concentration (wv-1) Initial rate (nmoles mg-1min-1)
0 0.12
10 0.16
25 0.15
Saturated trehalose 1.15
Saturated K2S04 0.96
  1. Initial rates were calculated from the aliquots taken over 0.5 to 3 h. The percentage conversions during these time periods were 1–10 percent and in a linear range.
