2,3-Butanediol (2,3-BDO) has immense industrial applications. Recently, microbial fermentation has emerged as an alternative way to produce this industrially important chemical. Although 2,3-BDO is produced by several microorganisms, the Klebsiella genera has an excellent production compared with other 2,3-BDO-producing microorganisms.

Pretreatment is necessary for lignocellulose to achieve a highly efficient enzymatic hydrolysis and fermentation. However, coincident with pretreatment, compounds inhibiting microorganism growth are formed. Some tissues or cells, such as thin-walled cells that easily hydrolyze, will be excessively degraded because
