326–330. 1965.—A sugar alcohol was isolated from the conidia of
Aspergillus oryzae
and identified as
d
-mannitol. Two types of
d
-mannitol dehydrogenases, nicotinamide adenine dinucleotide phosphate-linked and nicotinamide adenine dinucleotide-linked, were found in the conidia. Substrate specificities,
p
H optima, Michaelis-Menton constants, and the effects of inhibitors were studied.
d
-Mannitol was converted to fructose by the dehydrogenases. Synthesis of
d
-mannitol dehydrogenases was not observed during germination; the content of
d
-mannitol decreased at an early stage of germination. It was assumed, therefore, that
d
-mannitol might be used as the source of endogenous respiration and provide energy for the germination.
