Genome Analysis and Description of Three Novel Diazotrophs Geomonas Species Isolated From Paddy Soils.

ABSTRACT: Five strictly anaerobic strains, designated RG2^T, RG3, RG10^T, RF4^T, and RG29, were isolated from paddy soils in China. Strains RG2^T, RF4^T, RG10^T, RG3, and RG29 grew at temperatures ranging 5-42°C and pH ranging 5.5-8.5. Strains RG2^T, RF4^T, RG3, and RG29 could tolerate NaCl up to 0-0.7% (w/v) while strain RG10^T could tolerate NaCl up to 0-0.8% (w/v). The isolated strains showed the highest 16S rRNA gene sequence similarities to the type strains of Geomonas terrae Red111^T and Geomonas paludis Red736^T. In phylogenetic (based on 16S rRNA gene sequence) and phylogenomic trees, strains clustered with the members of the genus Geomonas. Menaquinone-8 was the
