(a) Respiration of C. jejuni 81–176 in response to different substrates (organic acids). Formate is one of the substrates that are highly metabolized by C. jejuni in the BIOLOG-AN system. (b) Chemotaxis of C. jejuni 81–176 in response to different substrates was determined as described in Zhulin et al.26. Different letters indicate statistically significant differences (P < 0.05). Horizontal dashed line indicates the lowest limit for quantification in these assays.
