Microbe involved in putrefaction. Pseudomonas putida KT2440

Pseudomonas putida strain KT2440. This strain was derived from a toluene-degrading isolate, Pseudomonas arvilla strain mt-2 (renamed Pseudomonas putida mt-2), by loss of its plasmid. It is the best characterized saprophytic bacteria, and the choice for cloning and gene expression in Gram-negative bacteria and can survive in the general environment (outside the laboratory). It is used in the development of biopesticides and is the first Gram-negative soil bacterium to be certified as a safety strain by the Recombinant DNA Advisory Committee.
