A problem of the stressful effect on growth and development of biomass in gas-liquid bioreactors with mechanical agitation has been discussed. As an alternative solution, the use of the helicoid type rotor is suggested. The application of the helicoid type rotor to a bioreactor for the cultivation of aerobic microorganisms, for example, sulfur-yellow mycelium tinder fungus Laetiporus sulphureus, allowed a 35% increase in the bioreactor productivity and reducing of the stressful stirring effect on the growth of the mycelial cultures.

Key words:  bioreactor,  helicoid,  mixing,  mycelium,  physicomechanical effect,  productivity,  rotor,  stirrer,  stress.
