Quantitative fermentation of unpretreated transgenic poplar by Caldicellulosiruptor bescii

Abstract

Metabolizing lignocellulosic feedstocks to industrial chemicals by microorganisms requires surmounting the recalcitrance caused by lignin. Here, the authors pair transgenic lignin modified poplar lines with engineered Caldicellusiruptor bescii to achieve biomass solubilization and ethanol conversion without pretreatment.
