Distribution and removal of antibiotic resistance genes during anaerobic sludge digestion with alkaline, thermal hydrolysis and ultrasonic pretreatments

Mengli Wang, Ruying Li, Qing Zhao

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 3, doi: 10.1007/s11783-019-1127-2

Abstract:

Sludge digestion is critical to control the spread of ARGs from wastewater to soil.

Fate of ARGs in three pretreatment-AD processes was investigated.

UP was more efficient for ARGs removal than AP and THP in pretreatment-AD process.

The total ARGs concentration showed significant correlation with 16S rRNA gene.

The bacteria carrying ARGs could be mainly affiliated with Proteobacteria.

A theoretical investigation on the thermal decomposition of pyridine and the effect of H

Ji Liu, Xinrui Fan, Wei Zhao, Shi-guan Yang, Wenluan Xie, Bin Hu, Qiang Lu

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 5,   Pages 1217-1228 doi: 10.1007/s11705-020-2024-8

Abstract: Pyridine is one of the main nitrogen-containing compounds in coal, and its pyrolytic mechanism to generate NO precursors (mainly NH and HCN) remains unclear. In this work, the possible pathways for the pyrolysis of pyridine to form HCN and/or NH were investigated by the density functional theory method, and the effects of H O on pyridine pyrolysis were also investigated. The results show that there are two possible reactions for the initial pyridine pyrolysis, i.e., internal hydrogen transfer and C–H bond homolysis, and that internal hydrogen transfer is more favorable. Nine possible reaction pathways following internal hydrogen transfer are obtained and analyzed. Among these pathways, pyridine prefers to produce HCN instead of NH . The existence of H O has significant effects on the decomposition of pyridine, as it participates in pyridine pyrolysis to form NH rather than HCN as the major product.
