Optimization of the Micromycete Cultivation Process – Basics of Growth Regulators and Biotesting Their Growth- stimulating Activity Concerning to Miscanthus giganteus

Miscanthus × giganteus Greef et Deu. is a perennial herbaceous introduced energy hybrid plant whose biomass used after processing to solid or liquid biofuel. The characterized by relatively low level of absorption pollutants from the soil vegetative organs, as its well-developed root system acts buffer, helps stabilize in and prevents their further spread. Sustainable Deu.(M. giganteus) growth on contaminated with heavy metals other хenobiotiсs depends adaptive performance, including establishment rate, resistance stressors. one way address this issue use regulators (PGRs), namely Stimpo Regoplant micromycete Cylindrocarpon obtusiusculum (Sacc.)
