Gas emissions from swine farms have an impact on air quality in the Republic of Korea. Swine manure stored in deep pits for a long time is a major source of harmful gas emissions. Therefore, we evaluated the mitigation of emissions of ammonia (NH3), hydrogen sulfide (H₂S) and amine gases from swine manure with biological products such as seaweed (Sargassum horneri) and a microbial consortium (Bacillus subtilis (1.2 × 10⁹ CFU/mL), Thiobacillus sp. (1.0 × 10¹⁰ CFU/mL) and Saccharomyces cerevisiae (2.0 × 109 CFU/mL)) used as additives due to their promising benefits for nutrient cycling. Overall, seaweed powder masking over two days provided notable control of over 98%–100% of the gas emissions. Furthermore, 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 NH₃, amines and H₂S over 10 days of treatment. The 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 alone. Without the consortium, seaweed decreased total volatile fatty acid (VFA) production. The proposed novel method of masking with a microbial consortium is promising for mitigating hazardous gases, simple, and environmentally beneficial. More research is warranted to determine the mechanisms underlying the seaweed and substrate interactions.

养猪场的气体排放对大韩民国的空气质量有影响。长期存放在深坑中的猪粪是有害气体排放的主要来源。因此，我们评估了使用生物产品（如海藻（Sargassum horneri）和微生物联盟（枯草芽孢杆菌（1.2×10 ⁹ CFU ））减轻猪粪中氨（NH 3），硫化氢（H ₂ S）和胺气体的排放的情况。/ mL），硫杆菌属（1.0×10 ¹⁰ CFU / mL）和酿酒酵母（2.0×109 CFU / mL）用作添加剂，因为它们对养分循环很有帮助。总体而言，两天的海藻粉遮蔽可显着控制超过98％–100％的气体排放。此外，当应用海藻粉末掩膜和微生物联合体时，显着控制气体排放尤其明显，从而使NH ₃，胺和H ₂的气体还原率达到100％治疗10天以上。结果还表明，与单独使用两种添加剂时相比，海藻粉末掩膜和微生物联合使用可以减少猪粪中的气体排放，从而减少了气味。没有财团，海藻降低了总挥发性脂肪酸（VFA）的产量。所提出的用微生物财团进行掩蔽的新颖方法有望减轻有害气体的产生，且简单且对环境有益。有必要进行更多的研究来确定海藻与底物相互作用的机理。
