Abstract
More than 100 thermophilic strains of microorganisms were selected. The generation of lipase and cellulase enzymes was investigated in dynamics for 28 most active strains. Fermentation of model mixtures of solid domestic wastes was carried out using the most active strains. A decrease in C/N was observed in the model substrates of SDW during fermentation. It was revealed in estimation of the toxicity of mixtures and their water extracts that the toxicity of all the tested mixtures for red California worms decreased after fermentation in al the tested mixtures. The results obtained can be used to develop the technology of solid-phase fermentation of solid domestic wastes.
