As of 2014, 26.4% of the total regulated odor emission facilities are occupied by livestock facilities. The odor of pigs is 10.9 OU·m3 / min per pig, which generates 15-50 times higher odor than other livestock. It is also a major cause of livestock odor complaint. Livestock odor substance is mixed 169 kinds of ingredients, 30 of which can be detected as odor. It contains sulfur, volatile fatty acids, phenols and indoles, ammonia and volatile amines. In particular, odorous substances of phenols and indole derivatives not included in domestic designated odor substances have high odor contribution and are not well decomposed. Therefore, it is known that despite the use of the odor reducing agent having a high removal rate of ammonia and the like, the residue is long and causes continuous discomfort. The odor problem using physical and chemical methods can not be solved because it can not solve the fundamental problem if the animal odor is not decomposed or removed. In the anaerobic environment, the bacteria present in the manure may produce volatile organic compounds, which are the cause of the odor, and the odor may be generated, and some microorganisms decomposing the odor substances may reduce the odor. B. subtillis, Saccharomyces cerevisiae, L. acidophillus, Enterococcus faecium, L. plantarum, B.coagulans, B. fermentum, B. thuringiensis, B. licheniormis, B. subtillis, Enterococcus faecium, Lactobacillus acidophllus, L. fermentum, L. lactis, L. plantarum, L. casei, L. brevis, Streptococcus faecium, Clostridium butyricum, Saccharomyces cerevisiae, Aspergillus niger, A. oryzae, and photosynthetic bacteria are used as odor-reducing microorganisms.
