- Abstract
An alkali and salt-tolerating strain FJAT-44876T was isolated from the bauxite residue sample. The 16S rRNA gene sequence and phylogenetic analysis suggest that strain FJAT-44876T was a member of the genus Evansella. It grew at 15–45 ℃ (optimum 20–25 ℃) and pH 6.5–11.0 (optimum pH 8.0–9.0) with 0–20% (w/v) NaCl (optimum 6–8%). The major fatty acids were anteiso-C15:0, iso-C15:0, anteiso-C17:0, iso-C17:0, and C16:0. The cell wall peptidoglycan contained meso-diaminopimelic acid and MK-7 as the menaquinone. The major polar lipids were diphosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine, and phosphatidylglycerol. The genomic DNA G+C content was 38.2%. The average nucleotide identity values between strain FJAT-44876T and closely related members were below the cutoff level for species delineation. Thus, based on the above results, strain FJAT-44876T represents a novel species of the genus Evansella, for which the name Evansella halocellulosilytica sp. nov., is proposed. The type strain is FJAT-44876T (=CCTCC AB 2016264T = DSM 104633T).
