Torrefaction-based Rhamnolipid Production

Short Introductive summary

A sequential, chemical-free torrefaction-based strategy for the production of the commercially important biosurfactant, rhamnolipids, from low quality wood waste is presented here. By adopting a simultaneous saccharification and fermentation strategy, the need for hydrolysis is bypassed in the process. The study offers a valorization opportunity for low-quality wood waste that is currently used for district heating purposes, as there are no alternative applications. It also presents a novel substrate for rhamnolipid production, with potential for upscaling. Rhamnolipids produced by the process form stable emulsions, which can be applied for oil recovery and also in personal care formulations.
