ABSTRACT

The levels of NADP+ and NAD+ in the mycelium of a cultured strain of P. nigricans Thom grown on the mineral medium with 2 per cent of glucose were studied as dependent on the time and method of addition of glucose. NaNO3 or their mixture to the medium, i. e. a single addition simultaneously with the spore inoculation or on the 7th day of the culture development, divided additions on the 5th--7th days. It was shown that addition of the above sources simultaneously with inoculation affected the levels of both dinucleotides by the 5th and 8th days. Analogous additions on the 7th day in 24 hours decreased the level of NAD+, while the NADP+ concentration increased after addition of a mixture of glucose and NANO3 and remained unchanged on their separate addition. When the above sources were added in divided doses the level of NADP+ increased till the 7th day and that of NAD+ till the end of the experiment (the 8th day).
