Abstract

Abstract:

Using spread-plate technique,actinobacterial strains were isolated from rhizospheric soil of 7 plants collected in the Arctic Yellow River Station(Ny-Alesund,the Arctic). 53 actinobacteria were indentified by the analysis of ARDRA and 16S rDNA sequences and were shown to represent strains from 8 genera: Streptomyces and Arthrobacter which is predominant and rare actinobacteria Rhodococcus,Saccharothrix,Rathayibacter,Micrococcus,Nocardia,Kribbella.

Key words: the Arctic, rhizosphere, actinobacteria, 16S rDNA
