TL;DR: It is shown that supplementation of micrometer-size magnetite particles to a methanogenic sludge enhanced (up to 33%) the methane production rate from propionate, a key intermediate in the anaerobic digestion of organic matter and a model substrate to study energy-limited syntrophic communities.

TL;DR: In this paper, a review on the current knowledge on the properties, reactivity and mobility in porous media of nZVI and their application to groundwater remediation is presented, where a specific focus is devoted to the methodologies to the colloidal stability of the NZVI slurries and to the available numerical tools for the simulation of laboratory and field scale mobility of the particles when injected in a porous media.

TL;DR: It is demonstrated that the positive effect of biochar is directly related to the electron-donating capacity (EDC) of the material, but is independent of its bulk electrical conductivity and specific surface area.

TL;DR: A batch-optimised mixture was investigated in a continuous fixed bed column reactor for the treatment of synthetic acid-mine drainage, showing that only 5% of the animals were still alive after 48h in presence of the contaminants, while the percentage increased to 73% when the nematodes were exposed to the solution eluted from the column.

TL;DR: Although the “Oil-Spill Snorkel” potentially represents a groundbreaking alternative to more expensive remediation options, further research efforts are needed to clarify factors and conditions affecting the snorkel-driven biodegradation processes and to identify suitable configurations for field applications.
