Mona Akbar, Muhammad Farooq Saleem Khan, Ling Qian, Hui Wang

Frontiers of Environmental Science & Engineering 2020, Volume 14, Issue 6, doi: 10.1007/s11783-020-1277-2

Abstract: Abstract • PAM degradation in thermophilic AD in comparison with mesophilic AD. • PAM degradation andits impact on thermophilic and mesophilic AD. • Enhanced methane yield in presence of PAM during thermophilicand mesophilic AD. • PAM degradation and microbial community analysis in thermophilic and mesophilicFurthermore, it degrades slowly and can deteriorate methane yield during anaerobic digestion (AD).The impact or fate of PAM in AD under thermophilic conditions is still unclear.
