Biochar as ammonia exchange biofilm carrier for enhanced aerobic nitrification in activated sludge.
Bioresour Technol
December 2024
The effects of biochar on aerobic nitrification in activated sludge were investigated in sequencing batch reactors. Biochar amended reactors exhibited 87-94 % lower ammonia in effluent and 16-71 % greater removal of total Kjeldahl nitrogen compared to control reactors. Quantitative qPCR analyses revealed that the relative abundance of ammonia oxidizing bacteria (AOB, amoA/16S rRNA genes) was greater in biochar than in control reactors.

- Increasing global population and urbanization are putting pressure on water resources, worsened by the persistent presence of organohalogen compounds which evade standard wastewater treatments and threaten ecosystem health.
- Recent research highlights the potential of pyrogenic carbons, including biochar, to improve the degradation of these harmful contaminants through various electron transfer mechanisms.
- Biochar offers multiple environmental benefits, such as carbon sequestration, adsorption of pollutants, and enhancing redox reactions, making it a promising candidate for remediation of organohalogen compounds in different environments.*
Cytochrome P450 enzymes are hemeproteins that catalyze the monooxygenation of a wide-range of structurally diverse substrates of endogenous and exogenous origin. These heme monooxygenases receive electrons from NADH/NADPH via electron transfer proteins. The cytochrome P450 enzymes, which constitute a diverse superfamily of more than 8,700 proteins, share a common tertiary fold but < 25% sequence identity.
