Stimulatory effect and adsorption behavior of rhamnolipids on lignocelluloses degradation system.

•Adding rhamnolipids could accelerate lignocellulose degrading process.•Batch adsorption experiments investigated adsorption process of rhamnolipids in lignocellulose degrading systems.•Adsorption kinetic models were built to estimate the adsorption pattern of rhamnolipids.•Mechanisms of the stimulatory effect of rhamnolipids were analysed by SEM and FTIR.
