The enzymes of pearl millet Pennisetum typhoideum malt: Part I. Amylases.

Pearl millet (Pennisetum typhQideum) in
the ungerminated Conditlon contained negligible
amylase activity. Germination of the
grain led to a marked increase in the alpha-amylase
activity, but only a slight increase in the alpha-amylase
activity. The diastatic activity of the
pearl millet malt was found to be less than
that reported in the literature for the malts of
barley, wheat and ragi. The optimum pH for
the activity of both alpha and beta-amyiases was 4·8
and the optimum temperature 60C. The
critical inactivation temperature for the alpha-
amylase at pH 4·8 was 45°C.
