Abstract

Microremediation of harmful radioactive waste such as uranium has been carried out by the endophytic actinomycetes strains isolated from the unnoticed fallen leaves of commonly available medicinal plant Azadirachta indica, which are considered as unique source. Among six actinobacteria isolates, one microbe (A5) effectively removed uranium in 12 h at temperature 30 °C and pH 8–9. Molecular characterization and phylogenetic analysis support the classification of the isolate A5 as a new strain which was named as Streptomyces sp. MINIYAA7 (Genbank accession number KF909129).
