Application of wastewater with high organic load for saline-sodic soil reclamation focusing on soil purification ability [PDF]

open access: yesGlobal Journal of Environmental Science and Management, 2017
Fresh water source scarcity in arid and semiarid area is limitation factor for saline-sodic soil reclamation. The reusing of agricultural drainage and industrial wastewater are preferred strategies for combating with this concern.

Peroxide-Mediated Oxygenation of Organic Compounds by Fungal Peroxygenases [PDF]

open access: yesAntioxidants, 2022
Unspecific peroxygenases (UPOs), whose sequences can be found in the genomes of thousands of filamentous fungi, many yeasts and certain fungus-like protists, are fascinating biocatalysts that transfer peroxide-borne oxygen (from H2O2 or R-OOH) with high efficiency to a wide range of organic substrates, including less or unactivated carbons and ...

Efficient alkane oxidation under combustion engine and atmospheric conditions

open access: yesCommunications Chemistry, 2021
Efficient autoxidation of organic compounds typically requires that they possess double bonds or oxygen-containing moieties, which is why alkanes were thought to contribute little to atmospheric organic aerosol formation.
