Screening assessment of ligninolytic and cellulolytic activity of basidium fungi strains and development of strains with high potential for waste fermentation catalyst "biovel-fermer"

Abstract

Waste from agricultural animals (LHCSH, liquid and solid wastes from agricultural animals) causes severe environmental pollution; which is why many countries have national and regional programs to reduce the negative pressure of these wastes on the environmental state of the environment. The actual task of microbiology is the search for alternative methods of waste disposal, among which the most promising is composting. Unlike other ways of utilizing the LFA (liquid and solid wastes) of the SZHZH (agricultural animals) this method allows obtaining valuable biofertilizers and soil soils that are cheaper than traditional fertilizers. It has now been established that, for composting under production conditions, when only a limited number of microorganisms are possible, the conversion of the initial substrate is most effective when various heterotrophic organisms, in particular fungi with high cellulolytic and lignolytic potential, are used as bioactivators. Since the lignolytic and cellulose potentials are the main characteristics of basidiomycetes determining their biodegradation ability, the selection of effective "white rot" fungus strains will be carried out based on preliminary screening of their ligno- and cellulolytic activity.
