An insertion sequence prepares Pseudomonas putida S12 for severe solvent stress.

Abstract excerpt

The novel insertion sequence ISS12 plays a key role in the tolerance of Pseudomonas putida S12 to sudden toluene stress. Under normal culturing conditions the P. putida S12 genome contained seven copies of ISS12. However, a P. putida S12 population growing to high cell density after sudden addition of a separate phase of toluene carried eight copies. The survival frequency of cells in this variant P. putida S12...
