[Enzyme activity of an actinomycete producer of carotenes and macrotetrolides].
The activity of pyruvate dehydrogenase and dehydrogenases of the tricarboxylic acid cycle was assayed in the mycelium of Streptomyces chrysomallus var. Carotenoides growing under different conditions of the medium. The activity of the enzymes increased when acetic, citric and succinic acids were added at different periods of the growth. Moreover, addition of the acids increased the time of intensive functioning of the dehydrogenases whose activity abruptly decreased after 60 h of the growth under the control conditions.
