“…Primary particles interact with gaseous precursors, followed by photochemical transformation pathways and lastly, transport and deposited as PM2.5 by meteorological process [25]. Organic carbon and sulfate control the formation of PM when NH3 presents in excessive amount [26]. Livestock operations contribute to PM2.5, and PM10.…”

Particulate matter (PM) represents an air quality management challenge for confined swine production systems. Because of the limited space and ventilation rate, PM can reach relatively high concentrations in swine barns. PM in swine barns possesses different physical, chemical, and biological characteristics than that in the atmosphere and other indoor environments. As a result, it exerts different environmental and health effects and creates some unique challenges regarding PM measurement and mitigation. Numerous research efforts have been made, generating massive data and information. However, relevant review reports are sporadic. This study aims to provide an updated comprehensive review of swine barn PM, focusing on publications since 1990. It covers various topics, including PM characteristics, sources, measurement methods, and in-barn mitigation technologies. Since PM in swine barns is of primarily biological origins, bioaerosols are reviewed in great detail. Relevant topics include bacterial/fungal counts, viruses, microbial community composition, antibiotic-resistant bacteria, antibiotic resistance genes, endotoxins, and (1→3)-β-D-glucans. For each topic, existing knowledge is summarized and discussed and knowledge gaps are identified. Overall, PM in swine barns is complicated in chemical and biological composition and highly variable in mass concentrations, size, and microbial abundance. Feed, feces, and skins constitute the major PM sources. Regarding in-barn PM mitigation, four technologies (oil/water sprinkling, ionization, alternation of feed and feeders, and recirculating air filtration) are dominant. However, none of them have been widely used in commercial barns. A collective discussion of major knowledge gaps and future research needs is offered at the end of the report.

“…The efficient control and recovery of environmental NH 3 gas and NH 4 + ions is very important in nitrogen treatment processes such as the Anammox process 104. N 2 O and NH 3 ‐derived nitrogen oxides are highly active greenhouse gases, and several nitrogen oxides formed by the photochemical reaction of NH 3 in fertilizers have recently been identified as particulate matter (PM) atmospheric pollutants 105–108. The technology used for NH 3 removal in the environmental field has been applied to bioproduction 37, 109, 110.…”

Amino acids are a valuable bioresource that contains both the acid form of carbon and the amine group of nitrogen. Amino acids not only constitute proteins and the building blocks for living organisms but also provide a key intermediate for controlling the nitrogen balance in cells. The production of amino acids using microorganisms has, along with the development of biotechnology, created a large market for biochemicals. In parallel, there have been various biochemical production methods using pulmonary proteins or direct amino acids as biomass through enzymatic bioconversion or whole‐cell biotransformation. The deamination of amino acids facilitated the applications of 2‐keto and acrylic acids, in particular, for biofuels of bio alcohol, pharmaceuticals, cosmetics, as building blocks for polymers, and other versatile industrial chemicals. In this review, we report on the application of amino acids derived from biochemicals initiated by deamination reactions using deaminase, ammonia‐lyase, and oxidase enzymes for biotechnology applications.
