[Effect of the cultivation temperature on the dynamics of the ATP and ADP levels and on the growth of P. nigricans Thom. Strains in the presence of various carbon sources].
The effect of the medium high temperature (28--28.6 degrees C) on the yield of the dry mycelium and the levels of ATP and ADP in the cells of the highly and low productive strains of P. nigricans Thom, 117 and B at different developmental periods (2, 5, 9 and 13 days) on the mineral medium using glucose, succinate or acetate as the carbon sources was studied. It was shown that the effect of the high temperature depended on the strain and the carbon source. The growth stimulating effect of this factor observed in strain 117 grown on the media with the above carbon sources and strain B grown on the media with glucose and acetate as the carbon sources was evident at different periods and later replaced by suppression. The growth of strain 177 in the presence of succinate was not inhibited, while that of strain B was suppressed during the whole developmental cycle. Such an effect of high temperature on the culture growth was the result of different supply of energy in the form of ATP to the strains which was confirmed by the study of the dynamics of the levels of ATP and ADP and their ratio in the strains during the developmental process.
