Fe stabilizes syntrophic volatile fatty acid oxidizing consortia under high organic load in chicken manure anaerobic digestion.
Volatile fatty acid (VFA) accumulation driven by thermodynamic constraints on syntrophic oxidation is a critical bottleneck in high-load anaerobic digestion (AD) of nitrogen-rich feedstocks. Using metagenomic and metatranscriptomic analyses of 172 bacterial genomes, thermodynamic calculations, and granule morphology, w...
