Two actinomycetes strains designated as DAS 131 and DAS 165, were isolated from cadmium contaminated agricultural soil of Gulbarga, Karnataka. The isolates were classified as Streptomyces spp. A plate diffusion assays showed to be resistant to cadmium [Cd (No3)2]. This method allowed a qualitative screen of the effects of metal on growth, on sporulation and in some cases, on secondary metabolic production. The strains have the best growth capacity in presence of 100mM Cdl-1 which is representative of their ability to soil colonization.
