Destructive processes are thought to be common in pre‐Cenozoic oil‐gas reservoirs. The timing, mechanism, and even identification of these processes, however, are difficult to clearly characterize, which obscures the evolution of such systems and the assessment of oil and gas reserves. Here, we reveal a new link between secondary chemical remanent ...
Biodegradation of 3,5,6-trichloro-2-pyridinol (TCP) in drylands is an important biological process of detoxification. Flooding in drylands can result in the formation of anaerobic habitats. However, little is known about the microbial metabolism of TCP in dryland soil under anaerobic conditions. Here, chlorpyrifos-contaminated dryland soil was incu...

L'accroissement des déchets et des sous-produits industriels a amené les chercheurs à trouver des solutions valorisantes pour répondre aux contraintes environnementales du 21ème siècle. L'industrie du ciment constitue déjà une filière de valorisation importante pour quelques-uns de ces produits tels que les cendres volantes, les laitiers de hauts f...
Coal gasification wastewater (CGWW) is a typical toxic and refractory industrial wastewater. Here, a novel phenol and ammonia recovery process (IPE) was employed for CGWWpretreatment, and the coupled system assemble by the IPE process with A(2)/O system (IPE-A(2)/O) were operated to enhance the treatment performance of CGWW. The results showed that...

Haloalkane dehalogenase DhaA catalyzes the hydrolysis of halogenated compounds by cleavage of the carbon halogen bond. However, DhaA suffers from poor environmental stability and difficult recovery, which significantly increase the cost of DhaA. Here, an effective enzyme immobilization strategy was developed to overcome the disadvantages of DhaA. D...

Petroleum hydrocarbons reach the deep-sea following natural and anthropogenic factors. The process by which they enter deep-sea microbial food webs and impact the biogeochemical cycling of carbon and other elements is unclear. Hydrostatic pressure (HP) is a distinctive parameter of the deep sea, although rarely investigated. Whether HP alone affect...
Coal gasification wastewater is a typical high phenol-containing, toxic and refractory industrial wastewater. Here, lab-scale anaerobic-anoxic-oxic system was employed to treat real coal gasification wastewater, and methanol was added to oxic tank as the co-substrate to enhance the removal of refractory organic pollutants. The results showed that t...
