Abstract
Out of different substrates, thermophilic n-alkane-assimilating hyphae fungi were isolated and the strains of Aspergillus fumigatus and Mucor lusitanicus selected for physiological investigations. The growth curves, obtained in hydrocarbon and glucose at different temperatures, showed three phases: 1) initial growth phase, 2) linear growth phase, and 3) lysis phase. Maximum dry matter and maximum protein content occurred within a range of 35-40 degrees C. During the entire time of growth the DNA content per mg dry matter was almost the same, i.e., 0.1-0.2 per cent. The ascertained specific protease activity of Aspergillus fumigatus correlated with protein synthesis and protein decomposition of the biomass. The results of our investigations are being discussed.
