Figure 2.
Biofilm formation of C. jejuni NCTC11168 and Δcas9 mutant at different time points. The Y axis is the OD570 value of crystal violet in biofilm. The results were obtained from three independent repeats. The asterisk (*) indicates statistical significance at P ≤ 0.05 for the comparison of C. jejuni NCTC11168, complemented, and the Δcas9 mutant.
