Pseudomonas putida Which Can Grow in the Presence of Toluene

ABSTRACT

A Pseudomonas putida strain able to grow in the presence of more than 50% toluene was isolated from soil. The strain was tolerant of other toxic solvents, including aliphatic hydrocarbons, alicyclic hydrocarbons, aromatic hydrocarbons, alcohols, and ethers. The stability of the solvent tolerance of strain IH-2000 was stimulated by addition of Mg²⁺ and Ca²⁺ to the medium containing toluene.
