“…It is important to maintain denitrification in order to sustain the function of a biofilter. Yasuda et al (2019) suggested nitrogen removal by the addition of thiosulfate. Further studies are needed on the conditions that prevent nitrogen accumulation and on the microbes contributing to denitrification.…”

Malodorous emissions are a crucial and inevitable issue during the decomposition of biological waste and contain a high concentration of ammonia. Biofiltration technology is a feasible, low-cost, energy-saving method that reduces and eliminates malodors without environmental impact. In the present study, we evaluated the effectiveness of compost from cattle manure and food waste as deodorizing media based on their removal of ammonia and the expression of ammonia-oxidizing genes, and identified the bacterial and archaeal communities in these media. Ammonia was removed by cattle manure compost, but not by food waste compost. The next-generation sequencing of 16S ribosomal RNA obtained from cattle manure compost revealed the presence of ammonia-oxidizing bacteria (AOB), including Cytophagia , Alphaproteobacteria , and Gammaproteobacteria , and ammonia-oxidizing archaea (AOA), such as Thaumarchaeota . In cattle manure compost, the bacterial and archaeal ammonia monooxygenase A ( amoA ) genes were both up-regulated after exposure to ammonia (fold ratio of 14.2±11.8 after/before), and the bacterial and archaeal communities were more homologous after than before exposure to ammonia, which indicates the adaptation of these communities to ammonia. These results suggest the potential of cattle manure compost as an efficient biological deodorization medium due to the activation of ammonia-oxidizing microbes, such as AOB and AOA, and the up-regulation of their amoA genes.

Nitrogen Fate and Microbial Community for Ammonia Removal in a Biofilter from Japanese livestock farms are approximately 6%, 13%, 8%, and 29%-45% of the total nitrogen contained in the manure of milking cows, beef cattle, pigs, and poultry, respectively. NH 3 causes environmental degradation, including eutrophication and acidification (Steinfeld et al. 2006, Sutton et al. 2008, in addition to an odor problem (Kuroda et al. 1996, Parker et al. 2012. Its concentration in the air is regulated as per the Offensive Odor Control Law of Japan (Ministry of the Environment 1995). Thus, the treatment of NH 3 -loaded gases is necessary for better management of livestock farming.
