Chromium [Cr(VI)] biosorption property of the newly isolated actinobacterial probiont Streptomyces werraensis LD22.

ABSTRACT: The present work demonstrates the heavy metal resistance and detoxification of Cr(VI) by the probiotic actinobacterial cultures isolated from chicken and goat feces. The actinobacterial isolates were screened for heavy metal resistance by qualitative, semiquantitative assays and Cr(VI) biosorption was determined by analytical techniques such as atomic absorption spectrophotometry and Fourier transform infrared spectrometry (FT-IR). All the tested actinobacterial isolates (n = 20) showed resistance toward K₂Cr₂O₇, NiCl₂, ZnCl₂, CuSO₄ and PbNO₃ at 20 mg L^-1 concentration. The maximum tolerance concentration values were found to be 200-250 mg L^-1 for K₂Cr₂O₇, 100
