Optimization of lignocellulolytic bacterial inoculum and substrate mix for lignocellulose degradation and product quality on co-composting of green waste with food waste

•Bacillus sp. F3X3 and Paenibacillus sp. F1A5 have lignocellulolytic activity.•The inoculum and the substrate mixture for green waste composting were optimized.•The best mixture has 50% green waste and 35% food waste, with a C/N ratio of 27.•Lignocellulose degradation with inoculation was 1.6-fold higher than the control.
