Emerging Strategies for Enhancing Propionate Conversion in Anaerobic Digestion: A Review

Molecules, Journal Year: 2023, Volume and Issue: 28(9), P. 3883 - 3883

Published: May 4, 2023

Anaerobic digestion (AD) is a triple-benefit biotechnology for organic waste treatment, renewable production, and carbon emission reduction. In the process of anaerobic digestion, pH, temperature, load, ammonia nitrogen, VFAs, other factors affect fermentation efficiency stability. The balance between generation consumption volatile fatty acids (VFAs) in key to stable AD operation. However, accumulation VFAs frequently occurs, especially propionate, because its oxidation has highest Gibbs free energy when compared VFAs. order solve this problem, some strategies, including buffering addition, suspension feeding, decreased loading rate, so on, have been proposed. Emerging methods, such as bioaugmentation, supplementary trace elements, addition electronic receptors, conductive materials, degasification dissolved hydrogen, recently researched, presenting promising results. But efficacy these methods still requires further studies tests regarding full-scale application. main objective paper provide comprehensive review mechanisms propionate generation, metabolic pathways influencing during process, recent literature experimental research related various strategies enhancing biodegradation. issues that must be addressed future focus are identified, potential directions development predicted.

Improving biomethane production from biochar-supplemented two-stage anaerobic digestion of on-farm feedstocks

Journal of Cleaner Production, Journal Year: 2023, Volume and Issue: 423, P. 138723 - 138723

Published: Sept. 6, 2023

On-farm feedstocks such as grass silage and cattle slurry present recalcitrant characteristics that can limit microbial conversion in biofuel production. Introducing a biochar supplement two-stage anaerobic digestion may facilitate feedstock hydrolysis improve energy yields biohydrogen biomethane The potentials were first investigated batch trials without supplement; results indicated yield of 230 L per kilogram (kg) volatile solid (VS) single-stage 275 L/kg VS digestion. In continuous trials, operated at an organic loading rate 4.0 g VS/L/d, the second-stage digester showed methane 237 with 10 g/L addition; this was 7% higher than addition. At same addition 212 VS; 3% Biochar found to enhance components hydrogen-producing phase, promote production methanogenesis, stabilize process. highest achieved 8.5 MJ hydrogen kg VS/L/d. demonstrated application could effectively gaseous
