Geminicoccus flavidas sp. nov. and Geminicoccus harenae sp. nov., two IAA-producing novel rare bacterial species inhabiting desert biological soil crusts.

ABSTRACT: Two Gram-staining negative strains (CPCC 101082^T and CPCC 101083^T) were isolated from biological sandy soil crusts samples collected from Badain Jaran desert, China. Both isolates were heterotrophic phototroph, could produce indole-3-acetic acid. The 16S rRNA gene sequences of these two strains were closely related to the members of the family Geminicoccaceae, showing high similarities with Geminicoccus roseus DSM 18922^T (96.9%) and Arboricoccus pini B29T1^T (90.1%), respectively. In phylogenetic tree based on 16S rRNA gene sequences, strain CPCC 101082^T and CPCC 101083^T formed a robust distinct clade with Geminicoccus roseus DSM 18922^T within the family Geminicoccaceae, which ind
