Figure 4From: Surface display of recombinant proteins on Escherichia coli by BclA exosporium of Bacillus anthracisEndoxylanase activity assay. After flask cultivation, whole cells were used for activity assay of endoxylanase (XynA) on cell surface. Symbols: ◊, E. coli host only without plasmid; ▲, E. coli harboring pTJ1-pelB-XynA; □, E. coli harboring pTJ1-pelB-BAN-XynA; ●, E. coli harboring pTJ1-BAN-XynA.Back to article page
