主 题：Seaweed Consortium Mitigation Ammonia H2S Volatile fatty acids(VFAs)
摘 要：Gas emissions from swine farms have an impact on air quality in the Republic of *** manure stored in deep pits for a long time is a major source of harmful gas ***,we evaluated the mitigation of emissions of ammonia(N H 3),hydrogen sulfide(H2S)and amine gases from swine manure with biological products such as seaweed(Sargassum homeri)and a microbial consortium(Bacillus subtilis(1.2×10^9 CFU/mL),Thiobacillus sp.(1.0×10^10 CFU/mL)and Saccharomyces cerevisiae(2.0×10^9 CFU/mL))used as additives due to their promising benefits for nutrient ***,seaweed powder masking over two days provided notable control of over 98%-100%of the gas ***,significant control of gas emissions was especially pronounced when seaweed powder masking along with a microbial consortium was applied,resulting in a gas reduction rate of 100%for NH 3,amines and H2S over 10 days of *** results also suggested that seaweed powder masking and a microbial consortium used in combination to reduce the gas emissions from swine manure reduced odour compared with that observed when the two additives were used *** the consortium,seaweed decreased total volatile fatty acid(VFA)*** proposed novel method of masking with a microbial consortium is promising for mitigating hazardous gases,simple,and environmentally *** research is warranted to determine the mechanisms underlying the seaweed and substrate interactions.
