“…The lower N loss caused by HTPRT suggested a more rapid degradation of organic matter and greater nitrogen retention (Liu et al 2017). These results agreed with the previous studies that the hyperthermophilic composting decreased the total N loss during the composting of cattle manure (Yamada et al 2007).…”

Composting technology comprising hyperthermophilic pretreatment (at ≥85 °C for 2 to 4 h, HTPRT) and aerobic composting was adopted to accelerate organic matter transformation and enhance nitrogen retention in chicken manure composting. The differences in physio-chemical parameters, successions, and metabolism functions of the bacterial community between HTPRT (85 °C, 4 h) and conventional composting (CK) were compared. The HTPRT composting system reached maturity 18 days in advance of CK. The HTPRT piles showed a lower maximum N loss (27.1% vs. 39.0%). The bacterial structure in the HTPRT system differed remarkably from that in CK. Ureibacillus (22.7%) and Ammoniibacillus (14.1%) were the most predominant species in the thermophilic phase of HTPRT pile, while the curing phase was dominated by Thermobifida (12.8%) and Saccharomonospora (11.8%). The authors’ results suggest that HTPRT improved the physical properties of the feedstock by reducing the bulk density, which favored microbiological activity, and thus improving composting efficiency.

“…When malodorous compounds arise during composting, microbes which degrade these compounds, as well as organic-substance-degrading microbes, concomitantly propagate (14,15). Such microbes might contribute to the repression of irritating gas emission from mature composts.…”

“…Compared to traditional composting (TC), the pretreatment with a hyperthermophilic reactor followed by TC (hyperthermophilic pretreatment composting, HPC) is superior in compost quality and e ciency through accelerating humi cation of composts (Huang et al 2019b), shortening the maturation period (Yamada et al 2007(Yamada et al , 2008 and increasing the N retention (Huang et al 2019a). Variations in the total bacterial community were mainly responsible for these advantages in HPC (Huang et al 2019a;Huang et al 2019b).…”

Proteolysis is the rate-limiting step involved in ammonification during organic nitrogen mineralization, and which relates to the amount of ammonia (NH3) volatilized and ammonium (NH4+) released in the composts. However, the dynamic of bacterial proteolytic communities related with NH3 emissions in composting systems are mostly unknown. This study aimed to examine and compare the effects of hyperthermophilic pretreatment composting (HPC) and traditional composting (TC) on (i) the difference of NH3 loss and nitrogenous compounds; (ii) the dynamics of the proteolytic bacterial community participated in proteolysis in composting systems on the basis of the functional genes (npr and sub); (iii) the link between the proteolytic bacterial community, biophysiochemical characteristics and NH3 loss. Results revealed that the HPC was able to decrease NH3 loss by 41.5% compared to TC during 60-day composting, together with an inhibitory effect on protease activity. Particularly, the relative abundances of proteolytic bacteria (Bacillus megaterium and Staphylococcus cohnii) with high proteolytic capability reduced significantly in HPC. Partial least-squares path modeling suggested physicochemical properties such as higher temperature as well as lower C/N ratio played a dominant role in affecting the abundance of proteolytic bacteria, which may have been an important factor contributing to the lower NH3 loss in HPC. These findings suggest that HPC can significantly reduce NH3 loss and enhance our understanding of proteolytic bacteria in composting systems.
