ABSTRACT
A novel bacterial cell-surface display system was developed in Escherichia coli using omp1, a hypothetical outer membrane protein of Zymomonas mobilis. By using this system, we successfully expressed β-amylase gene of sweet potato in E. coli. The display of enzyme on the membrane surface was also confirmed. The recombinant β-amylase showed to significantly increase hydrolytic activity toward soluble starch. Our results provide a basis for constructing an engineered Z. mobilis strain directly fermenting raw starch to produce ethanol.

    In Zymomonas mobilis, the extracellular levansucrase (SacB) and extracellular sucrase (SacC) are involved in sucrose hydrolysis. Genes coding for these two enzymes (s acB and sacC) are arranged in a cluster in the genome and separated by a short intervening sequence. The level of sacC transcript...
