The results of solid-phase and deep cultivation of the Siberian strain Fp6-17 Fomitopsis pinicola (Sw.) P. Karst. are presented. Growth parameters were determined on cellulose-containing agarized media and plant substrates with the addition of a solid phase after hydrodynamic activation of fir needles and sawdust of birch. Radial growth rate 3.0–4.3 mm / day; growth coefficient 37–64. Changes in polysaccharides in activated birch sawdust during fermentation noted, despite the low growth coefficient of the fungus. After hydrodynamic activation, the content of easily hydrolysable polysaccharides increased by 9 %, the proportion of hardly hydrolysable polysaccharides decreased by 8%. After further solid-phase cultivation, the content of easily and hardly hydrolysable polysaccharides decreased by 10 and 23%, respectively. The conditions for the deep cultivation of the strain Fp6-17 on a modified Norkrans medium with microcrystalline cellulose selected. At 26 °C and a pH of 4.6 on the seventh day, the maximum activity of carboxymethyl cellulase was 13.6 units / ml; biomass yield – 16.2 g/l. The optimal composition of the solid phase medium was selected after hydrodynamic processing of fir needles and sawdust of birch with enrichment of (NH4)2SO4. The maximum activity of the enzyme was 14.2 u/ml. With high enzymatic activity in the culture fluid, the formation of small globules with a diameter of up to 5 mm and a smaller amount of biomass is noted. At lower enzyme indices, in most cases a greater increase in biomass recorded due to the formation of large ellipsoid pellets with a fringed edge.
