[Biosynthesis of levorin and activity of several enzyme systems of Streptomyces levoris depending on culture conditions].
The regularities of changes in the main oxidation-reduction enzymes of the tricarboxylic acid cycle (TAC) and the pentose cycle were studied under different cultivation conditions: with the use of the control soybean-corn-hydrol medium and the medium with addition of a biostimulant produced by C. tropicalis. It was shown that the activity levels of the dehydrogenase systems of the TAC and the pentose cycle of S. levoris grown in the presence of the biostimulant were higher. The increase in the production levels of levorin due to addition of the biostimulant was connected with the activity of the systems responsible for regeneration of NADP.H2.
