- Abstract
The article presents a study on the malodors from pig manure. It notes that pig manure is comprised of urine, undigested food, and metabolites of anaerobic bacteria which causes a mixture of odorants. The study aims to reduce emissions of toxic odorants through modifying the conditions in the pig manure for an altered microbial community. It mentions that sugar, carbohydrate-rich waste, and bacterial corrections were tried for their impact on manure pH, bacterial community, and gaseous emissions. Moreover, it reveals that adding maltose syrup and wheat flour to a manure storage pit reduces the pH.
