What is Cadmium biosorption by Streptomyces sp. F4 isolated from former uranium mine about?

## Abstract 46 actinomycetes were isolated from two polluted sites and one unpolluted site. One strain, F4, was selected through primary qualitative screening assays because of its cadmium resistance, and physiologically and taxonomically characterized. F4 was able to grow at 7.5% NaCl and 100 μg/ml lysozyme and at a pH between 6 and 10. 16S rDNA sequence analysis showed that F4 was closely related to __Streptomyces tendae__. Growth of __Streptomyces__ sp. F4 on culture medium with 8 mg/l Cd^2+^ for 8 days showed 80% inhibition. Maximum specific biosorption was 41.7 mg Cd^2+^/g dry weight after 7 days of growth and highest Cd^2+^ concentration was found in the cell wall (41.2%). The exopolysaccharide layer only contained 7.4%, whereas 39.4% of Cd^2+^ was found in the cytosolic fraction. Twelve % was found in the ribosomes and membrane fraction. This was verified with TEM, showing __Streptomyces__ sp. F4 cytoplasm with dark granulate appearance. This study could present the potential capacity of __Streptomyces__ sp. F4 for Cd^2+^ bioremediation. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
