A minimal active microbial consortium (MAMC-M48) for lignocellulose degradation, optimized through reductive screening from 18 candidate strains. The 5-member consortium consists of Stenotrophomonas maltophilia JN40, Paenibacillus sp. PALXIL05, Microbacterium sp. UYFA68, Chryseobacterium taiwanense DUCC3723, and Brevundimonas sp. R3. Enriched from soil bacteria on sugarcane waste, this synthetic community achieves 50.6% degradation of all lignocellulose fractions, reaching 96.5% of the degradation rate observed with the full 18-species pool, demonstrating high efficiency with minimal complexity.
