Enhanced removal of humic substances in effluent organic matter from a leachate treatment system via biological upgradation of molecular structure.

Environmental technology

Chen M, Jin X, Wang Y, Wang X, Cai Z, Sun X.
PMID: 33979274
Environ Technol. 2021 May 28;1-11. doi: 10.1080/09593330.2021.1929505. Epub 2021 May 28.

Biological upgradation (BU) process was proposed, with the goal of converting the molecular structure, for improving the coagulation effect on humic substances (HS) in effluent organic matter from the membrane bioreactor of a leachate treatment system. Enhancement of coagulation...

Anaerobic oxidation of methane mediated by microbial extracellular respiration.

Environmental microbiology reports

Zhang X, Yuan Z, Hu S.
PMID: 34523810
Environ Microbiol Rep. 2021 Dec;13(6):790-804. doi: 10.1111/1758-2229.13008. Epub 2021 Sep 15.

Anaerobic oxidation of methane (AOM) can be microbially mediated by the reduction of different terminal electron acceptors. AOM coupled to reduction of sulfate, manganese/iron oxides, humic substances, selenate, arsenic and other artificial extracellular electron acceptors are recognized as processes...

Comparative analysis of in vivo and in silico toxicity evaluation of the organoiodine compounds towards D.magna using multivariate chemometric approach: A study on the example of amiodarone phototransformation products.
