Isolation and identification of a mercury resistant strain

Abstract

A mercury resistant strain 2 was isolated. It was identified as Pseudomonas putida and designated as Pseudomonas putida 2 on the basis of morphological and biochemical analysis in combination with phylogenetic analysis. Strain 2 could tolerate and aerobically grow in the medium containing up to of 50 mg•dm 3 Hg(II). The highest Hg(II) removal of strain 2 was 85.2% at an initial concentration of 15 mg•dm 3 Hg(II). The highest Hg(II) removal of strain 2 was obseved at 30 °C and pH 7.
