Immobilizing organic pollutants by adsorption of biochar in farmland soil is a cost-effective remediation method for contaminated soil. In situ regeneration biochars biodegradation to remove biochar-adsorbed potential way maintain the performance lower cost. Adsorption largely dependent on pyrolysis temperature biochars.

It observed that 37.5~47.9% moderate temperature-pyrolyzed produced 400 and 500 °C were biodegraded, less than high ≥600 (48.8~60.8%) low ≤300 (63.4~92.5%).

It has been widely accepted that iron plays an important role in stimulating the activity of anammox bacteria, which contain many clusters for electron transport cells. However, whether bacteria could directly use and how to uptake Fe(III) have long-time ignored. Here, we found micrometer-scale magnetite with size 10–20 μm significantly promoted bacterial by core uptake. Anammox cannot utilize as they are unable secrete siderophore extracellular transfer intracellular. In anaerobic consortia at presence magnetite, synthesis belonging Alphaproteobacteria, Candidate phylum, Chloroflexi secreted abundant siderophores, combined ionized from form siderophore-Fe(III) complexes. These complexes were then used via a specific outer membrane receptor transported transporter protein periplasm, further releasing Fe(III). Cytochrome c was formed complex reduction, assimilation Fe–S heme B increase capability. This study reveals siderophore-mediated cooperation implies driving nitrogen conversion artificial or natural system.
