Figure 1. Different growth stages of B. bacteriovorus HD100 preying on P. putida KT2440.

Figure 1

(a) TEM image of P. putida KT2440 accumulating mcl-PHA. (b) SEM image of a co-culture of B. bacteriovorus HD100 preying on P. putida KT2440. Different predator growth stages can be distinguished: Attack phase predator cells, entering the periplasm of the prey and growing in rounded prey cells (bdelloplast). (c) Detailed TEM image of predator cell development within a bdelloplast. (d) Detailed SEM image of prey cell lysis and release of predator progeny into the medium. (e) PHA granules released by B. bacteriovorus Bd3709 mutant after 24 h of predation upon P. putida KT2440.
