Functional Display of an Amoebic Chitinase in Escherichia coli Expressing the Catalytic Domain of EhCHT1 on the Bacterial Cell Surface.

Poor solubility is the main drawback of the direct industrial exploitation of chitin, the second most abundant biopolymer after cellulose. Chemical methods are conventional to solubilize chitin from natural sources. Enzymatic hydrolysis of soluble chitinous substrates is a promising approach to obtain value-added by-products, such as N-acetylglucosamine units or low molecular weight chito-oligomers.
