Isolation and characterization of new metallotolernat bacilli strains

Abstract

A total of ten mesophilic and thermotolerant metallotolerant bacilli were isolated from water and soil samples and identified up to species. The morphological, physiological and biochemical properties of metallotolerant strains were described, as well as 16S rDNA sequence analyses were carried out. The stability of isolates was demonstrated in the presence of different concentrations of Cd2+, Cu2+, Zn2+ and Ni2+ in growth media. The ability of isolates to accumulate mentioned metals was studied. © 2010 Taylor and Francis Group, LLC.
