Bacterial degradation of chlorophenols and their derivatives
Pankaj Arora,Hanhong Bae +1 more
TL;DR: The biochemical and genetic basis of the degradation of CPs and their derivatives is described, which includes the metabolic pathways for degradation in bacteria and the genes and enzymes involved in the degradation in various CPs.

An overview of chlorophenols as contaminants and their removal from wastewater by adsorption: A review.
Zaharaddeen N. Garba,Zaharaddeen N. Garba,Weiming Zhou,Ibrahim Lawan,Wei Xiao,Mingxi Zhang,Liwei Wang,Lihui Chen,Zhanhui Yuan +8 more
TL;DR: The π-π dispersion interaction mechanism, hydrogen bonding formation mechanism, and the electron donor-acceptor complex mechanism were proposed for the chlorophenols adsorption onto various adsorbents with the help of current literature.
Journal ArticleDOI
The toxic effects of chlorophenols and associated mechanisms in fish
TL;DR: Recent studies on the alteration of DNA methylation by CPs through high-throughput DNA sequencing analysis provide new insights into the understanding of the epigenetic mechanisms underlying CPs toxicity.

Improved performance of simultaneous nitrification and denitrification via nitrite in an oxygen-limited SBR by alternating the DO.
Lilong Yan,Shuang Liu,Qingping Liu,Mingyue Zhang,Yue Liu,Yan Wen,Zhonglin Chen,Ying Zhang,Qianqian Yang +8 more
TL;DR: Analysis showed that the metabolic potential of the bacterial community for amino acids, nucleotides, coenzymes and inorganic ions decreased, while the relative abundance of key enzymes involved in nitrification and denitrification, and the relative population of denitrifying bacteria increased when the DO decreased.

Persulfate non-radical activation by nano-CuO for efficient removal of chlorinated organic compounds: Reduced graphene oxide-assisted and CuO (0 0 1) facet-dependent
Xiaodong Du,Yongqing Zhang,Yongqing Zhang,Fan Si,Chenhui Yao,Meimei Du,Imtyaz Hussain,Hyunook Kim,Shaobin Huang,Zhang Lin,Waseem Hayat +10 more
TL;DR: In this article, reduced graphene oxide modified spindle-like CuO (CuO/rGO, no preferential exposed crystal facet) and sheet-like cuO-persulfate system exhibited much better 2,4,6-trichlorophenol (TCP) removal rate than spindle like CuO-polygonal polysilicon dioxide (SiO)-based CuO.
