Influence of Bacillus strains on ammonia emission during chicken manure storage and their tolerance to pH,salt and ammonium
Livestock husbandry is the main source of ammonia emissions,and the large amount of ammonia has emitted during manure storage which exacerbates air pollution.In this study,the effect of inoculation with Bacillus isolated from soil on the ammonia emission was investigated during the chicken manure storage through a manure incubation at constant temperature.Moreover,their tolerances to pH,salt and ammonium were determined in pure culture.The results showed that the inoculation with Bacillus H1-10 and H2-6 significantly reduced the cumulative ammonia emission from chicken manure,by 8.34%and 11.85%compared with the non-inoculated control,respectively(p<0.05).Both strains H1-10 and H2-6 were able to grow and metabolize under pure culture conditions of strong alkali,high salinity and high ammonia.This study will provide novel idea to decrease ammonia emission during the storage of livestock and poultry manures with Bacillus strains,and provide microbial resources to develop effective microbial agents.
