The intensification of poultry farming around the world leads to an increase in the volume of waste, particularly poultry manure, which puts a great burden on the environment, polluting the air, soil and water. Composting is the most cost-efficient and environmentally friendly technology among the currently available methods of poultry manure utilization. The resulting product is an organic fertilizer of high quality with a high content of macro and microelements, which not only increases the yield of agricultural crops, but also has a positive effect on the soil structure and its fertility. The process of poultry manure composting can be improved with the addition of effective microorganisms in order not only to reduce the maturation period of compost, but also for their further positive impact on the growth, development and nutrition of plants. In this article, we have isolated and studied microorganisms from fresh chicken manure. The species of microorganisms that have a high cellulose-destroying and growth-stimulating ability has been determined based on a fragment of the 16S rRNA gene. Thus, in the course of this work, the most promising strains of microorganisms have been selected for further development of biologics based on them.
