We recommend using the α-Amylase SD Assay Kit (High Sensitivity Method) (K-AMYLSD).

We suggest that the fermentation broth is simply adjusted to 5.0 with acid or base and this can be used directly in the assay. The sensitivity can then be increased by increasing incubation time up to 4 hours. Appropriate adjustments then need to be made to the calculations.
