Enhancing Anaerobic Digestion of Lignocellulosic Biomass through Tailored Microbial Inoculums

Short Introductive summary

Lignocellulosic biomass is a promising biofuel source, but its complex structure hinders efficient anaerobic digestion (AD) for biogas production. Critical factors for AD success include temperature, microbial communities, carbon-to-nitrogen ratio, and substrate-to-inoculum ratio. Traditional AD processes using diverse microbial consortia often face nutrient competition, reducing biogas yield. This study proposes an innovative approach: a tailored inoculum with specific microorganisms for efficient lignocellulose degradation and increased biogas production through syntrophy. The goal is to identify fungi, bacteria, and archaea for optimized AD, comparing their performance with traditional inoculum-based AD. The study’s insights are valuable for large-scale facilities converting lignocellulosic biomass into renewable fuel.
