TL;DR: In this paper, Fourier transform infrared spectroscopy (FT-IR) was used to monitor the composting process, evaluate the degradation rate and thus determine the maturity of a sewage sludge-based compost mixture.

TL;DR: The results of both analytical methods confirm the presence of anaerobic ammonium oxidizing bacteria as the predominant species along with other Planctomycete-like bacteria and offer the simultaneous removals of nitrogen and COD in the wastewater.

TL;DR: This study proposes a real catalytic process that is capable of degrading extremely recalcitrant 1,4-dioxane using a combination of alumina-supported metallic palladium (Pd/Al2O3) with PMS and proposes that surface-bound sulfate radicals were probably the dominant active species.

TL;DR: Fe-g-C3N4-PMS had a wide effective pH range, and its reactivity was nearly independent of natural illumination, and quenching experiments revealed that nonradical oxidation contributed to the observed degradation.

TL;DR: A obligate aerobic methanotrophic bacterium, Methylomonas denitrificans FJG1, has been demonstrated to couple partial denitrification with methane oxidation, under hypoxia conditions, releasing nitrous oxide as a terminal product, which implies an important but unknown role of aerobic meethanotrophs in global climate change through their influence on both the methane and nitrogen cycles in ecosystems.
