Viable cell counts of C. jejuni strains coincubated with P. putida DSM 50198. (A) C. jejuni strains DSM 4688 (filled diamonds), EuC300 (open squares), GC3 (filled squares), EuC196 (filled triangles), GC162 (open circles), EuC245 (filled circles), and GC8 (open triangles) were coincubated with P. putida DSM 50198, and some survived the aerobic growth conditions for more than 48 h. (B) When incubated without the support of P. putida, none of the C. jejuni strains could survive 18 h of aerobic incubation.
