| Abstract | In this work, we studied screening strains of microorganisms that exhibit high proteolytic properties and can fix atmospheric nitrogen to speed up the process of biodegradation of bird droppings. There had been established that the Pseudomonasputida 90 biovar A (171) strain exhibits the highest enzymatic ability. Its addition to chicken manure contributed to an increase in the microflora titer from 104 CFU/ml to 1011 CFU/ml after 15-20days. The study of strains capable of utilizing atmospheric nitrogen showed the best property of the culture Azotobacterchroococcum 31/8R. Treatment of bird droppings with the studied strain reduced the level of ammonia in the environment from 93mg/m3 to 14mg/m3. In the structure of the total DNA of this strain, it identified genes encoding all the enzymes responsible for the process of nitrogen fixation. The combined use of selected cultures of microorganisms can be the basis for the development of a biological product that speeds up the process of natural decomposition of bird droppings. |
