Termite-Based Biorefinery as an Innovative Model for Biohydrogen and Biomethane Productions
摘要
Lignocellulosic biomass is a renewable resource with significant potential for sustainable energy production. Termites, as natural bioreactors, offer a unique model for efficient lignocellulose degradation, driven by their gut microbiota composed of bacteria, archaea, and eukaryotic symbionts. This microbial symbiosis enables termites to ferment lignocellulose into energy resources including biohydrogen and methane. The symbiotic mechanisms, underpinned by the gut’s physicochemical conditions, facilitate anaerobic fermentation and carbon recycling. Termite gut symbionts demonstrate unparalleled efficiency in converting cellulosic substrates into biohydrogen and biomethane, with rates surpassing those of other natural systems. Here we explore the lignocellulolytic capabilities of termite gut systems, emphasizing their role as biomimetic models for biohydrogen and biomethane production from lignocellulosic biomass. The chapter identifies critical research gaps in understanding symbiont functions and fermentation dynamics while highlighting termites’ potential for sustainable biomass utilization. By leveraging termite-inspired biotechnologies, we can address global challenges in renewable energy and waste management, paving the way for innovative solutions in lignocellulosic biorefineries.
