The effect of NKLnc expression on host bacterial growth. (A) Escherichia coli was transformed with the backbone vector or the vector carrying the NKLnc gene inducible by IPTG. The bacteria were cultured in the presence of IPTG and determined for growth at different hours. (B,C) The above E. coli cells were plated in an agar plate supplemented with or without IPTG, and bacterial growth was observed after overnight incubation. Scale bar, 1 cm (B). The percentages of bacterial survival were determined (C). Values are the means of triplicate assays and shown as means ± S.D. *** p < 0.001.
