Abstract

Cell-surface display of designer cellulosomes complexes has attracted increased interest in recent years. These engineered microorganisms can efficiently degrade lignocellulosic biomass that represents an abundant resource for conversion into fermentable sugars, suitable for production of biofuels. The designer cellulosome is an artificial enzymatic complex that mimics the architecture of the natural cellulosome and allows the control of the positions, type, and copy number of the cellulosomal enzymes within the complex. Lactobacillus plantarum is an attractive candidate for metabolic engineering of lignocellulosic biomass to biofuels, as its natural characteristics include high ethanol and acid tolerance and the ability to metabolize hexose sugars. In recent years, successful expression of a variety of designer cellulosomes on the cell surface of this bacterium has been demonstrated using the cell-consortium approach. This strategy minimized genomic interference on each strain upon genetic engineering, thereby maximizing the ability of each strain to grow, express, and secrete each enzyme. In addition, this strategy allows stoichiometric control of the cellulosome elements and facile exchange of the secreted proteins. A detailed procedure for display of designer cellulosomes on the cell surface of L. plantarum is described in this chapter.
