Objective. To analyse literature on microbiological aspects of composting in general and chicken manure in particular. To compare the features and consequences of composting using resident microbiota and introduction of specially selected microorganisms to the composted substrate. Methods. Analysis. Synthesis. Generalization. Results. Composting of chicken manure is a process carried out to ferment and stabilize organic waste. Destruction or significant reduction of the number of pathogenic microorganisms, the transformation of nitrogen and carbon into stable organic forms, the reduction of the volume of waste and the improvement of their fertilizing qualities are among the important consequences of composting as a method of processing chicken manure. Inoculation of chicken manure using effective selected microorganisms is a measure that stimulates the proliferation of resident microbial populations, increases the number of microbiota in communities capable of generating the desired enzymes, and thus significantly speeds up and improves the composting process. Currently, technologies for composting chicken manure using exogenous microorganisms have been developed, which allow solving the key problem associated with nitrogen losses, which increases the value of manure as a source of organic fertilizers. However, the large species and numerical diversity of the “aboriginal” microbiota in poultry manure complicates the process of introducing agronomically valuable microorganisms to the composted substrate. The complexity of the composting process is also due to the impossibility of generalizing the initial properties and composition of the manure, which depend on the diet of poultry, management conditions on farms, etc. Conclusion. A brief analysis of the role of microorganisms in chicken manure composting shows the need for mandatory optimization of the carbon/nitrogen ratio in the substrate, taking into account microbiological aspects of the process, the importance of using selected microorganisms to improve the features of the final product.
