gen. nov., sp. nov., isolated from rice paddy soil No Access

Abstract

A novel Gram-stain-negative, aerobic, motile and pleomorphic rod-shaped bacterial strain, designated COJ-58, was isolated from rice paddy soil. Strain COJ-58 grew optimally at 20–30 °C, at pH 5.0–8.0 and with 0–1.0 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain COJ-58 forms a distinct lineage within the family , with highest similarity to SVCO-16 (95.9 %), Y9 (95.8 %), e F-7 (95.7 %) and R5-392 (95.6 %), respectively. The average nucleotide identity, digital DNA–DNA hybridization, average amino acid identity and percentage of conserved proteins values between the genomes of strain COJ-58 and its closely related taxa are ≤77.2 %, ≤21.6 %, ≤68.3 % and ≤61.3 %, respectively. The genome size of strain COJ-58 is 4.9 Mb and the genomic DNA G + C content is 63.7 mol%. The major fatty acids are C 7, C and summed feature 2 (C 3-OH and/or iso-C I). The differential phenotypic and genotypic characteristics of strain COJ-58 indicate that it represents a novel genus and species, for which the name gen. nov., sp. nov. is proposed, with strain COJ-58 (=KACC 22108=JCM 34744) as the type strain.
