Simultaneous display of bacterial and fungal Lipases on the cell surface of Bacillus subtilis
A small cell wall-binding domain (CWBc) of the Bacillus subtilis peptidoglycan hydrolase CwlC fused to B. subtilis lipase B was able to be localized on the cell wall of B. subtilis. With the aim of developing an efficient lipid-hydrolyzing bacterium with two different lipases on the cell surface, plasmids possessing genes for LipB-CWBc and CWBb-CutL (the cell wall-binding domain of CwlB fused to the Aspergillus oryzae lipolytic enzyme CutL) were constructed. B. subtilis harboring these plasmids accumulated considerable amounts of both lipases on the cell surface.
