Figure 1. Toluene degradation by P. putida wildtype and mutualistic strains.

Figure 1

(a) Pathway of toluene degradation identified in P. putida F1, adapted from Parales et al.33, and partial pathways carried out by mutant strains PpF4 and PpF10732. (b) Colony growth of mono- and cocultures of P. putida strains (wildtype PpF1, mutants PpF4 and PpF107) on agar plate in presence of toluene vapor as sole carbon source for 5 days. One-μl droplets of cell suspension (pure or mixed 1:1) were pipetted onto the agar surface. (c) Growth of mono- and cocultures (mixed 1:1) of PpF1, PpF4 and PpF107 in liquid medium with toluene as sole carbon source. Bacteria were incubating without shaking and toluene was provided via the gas phase.
