Bidirectional Enhancement of Nitrogen Removal by Indigenous Synergetic Microalgal–Bacterial Consortia in Harsh Low-C/N Wastewater

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(12), P. 5394 - 5404

Published: March 11, 2024

Conventional microalgal–bacterial consortia have limited capacity to treat low-C/N wastewater due carbon limitation and single nitrogen (N) removal mode. In this work, indigenous synergetic with high N performance bidirectional interaction were successful in treating rare earth tailing wastewaters low-C/N. Ammonia reached 0.89 mg L–1 h–1, 1.84-fold more efficient than a common system. Metagenomics-based metabolic reconstruction revealed interactions. The presence of microalgae increased the abundance bacterial N-related genes by 1.5- 57-fold. Similarly, bacteria microalgal assimilation 2.5- 15.8-fold. Furthermore, nine species isolated, promotion system was verified. mechanism enhanced indole-3-acetic acid revealed. addition, mode ensured scavenging toxic byproducts from nitrate metabolism maintain stability Collectively, enhancement microalgae-bacteria established as an effective strategy broaden stable application for treatment low C/N ratio wastewater.

Microalgal-bacterial granular sludge can remove complex organics from municipal wastewater with algae-bacteria interactions

Communications Earth & Environment, Journal Year: 2024, Volume and Issue: 5(1)

Published: June 24, 2024

Abstract Interactions between algae and bacteria are pivotal in transforming complex organics for microalgal-bacterial granular sludge process, but the intrinsic removal mechanisms have not been well understood. Here, we investigate by which removed from municipal wastewater. Complex can be disposed during day-night cycles, significantly impacted carbon-to-nitrogen ratio influent. Upregulated gap2 gpmA genes enhanced conversion of into CO 2 , mediated interactions Chlorophyceae with Acidobacteriae / Sumerlaeia Fimbriimonadia upregulated petH gene Cyanobacteria strengthened fixation biomass. The breakdown starch, glycerol, fatty acid were depended on Actinobacteriota Chloroflexia Verrucomicrobiae Desulfobacterota I respectively. These findings provide new insights through symbiosis contribute to our understanding carbon cycle natural aquatic ecosystems.
