Biogas and biomethane production
Tailored Microbial Consortia for Enhanced Biomethane Production from Apple Pomace: Bioprocess Improvement and Kinetics
Short Introductive summary
The anaerobic digestion of lignocellulosic residues such as apple pomace is often limited by slow hydrolysis and insufficient microbial adaptation. This study developed an enriched microbial inoculum specifically tailored for apple pomace degradation, promoting hydrolytic microorganisms and improving biomass breakdown. Metagenomic analysis confirmed the enrichment of hydrolytic taxa. The adapted inoculum enhanced process performance, increasing biomethane production by approximately 40% and eliminating the typical lag phase. These results highlight inoculum enrichment and bioaugmentation as effective strategies to improve lignocellulosic conversion in anaerobic digestion systems.
