Potential microbial strains for composting cattle and horse manure

The potential of effective microorganisms in composting animal manure might be significant. This work aimed at isolating promising microbial strains for composting cattle and horse manure. A total of forty-five isolates have been isolated from soils of Northern Kazakhstan as well as cattle and horse manure. These microorganisms were extensively studied for their cellulose-degrading capacity, non-pathogenicity, protease, nitrogenase and catalase activities, as well as their growth stimulation, antagonistic ability, and growth rate. As a result, 21 potent strains were selected and genotyped for the creation of microbial consortia. These consortia were then used in small-scale composting experiments with cattle and horse manure. Further studies evaluated the effectiveness of the composting process and the quality of the compost produced. The study yielded promising results, identifying effective microbial strains that could enhance the composting of horse and cattle manure.
