  • Title: Sphingomonas suaedae sp. nov., a chitin-degrading strain isolated from rhizosphere soil of Suaeda salsa.

    Journal: Int J Syst Evol Microbiol; 2020 Jun; 70(6):3816-3823. PubMed ID: 32459168.
    Abstract:
    A Gram-stain-negative, aerobic, chitin-degrading, motile bacterial strain with a single polar flagellum, designated XS-10T, was isolated from saline soil sampled from the rhizosphere of Suaeda salsa, Tumd Right Banner, Inner Mongolia, PR China. Strain XS-10T grew at 10-40 °C (optimum, 35 °C), pH 5.0-9.0 (optimum, pH 8.0) and 0-12.5% NaCl (optimum 2.0 %). The phylogenetic analysis based on both the 16S rRNA gene and the phylogenomic tree revealed that strain XS-10T formed a clade with Sphingomonas turrisvirgatae MCT13T and Sphingomonas koreensis JSS-26T, sharing 98.4 and 97.5 % 16S rRNA gene similarities to S. koreensis JSS-26T and S. turrisvirgatae MCT13T, respectively. Spermidine and Q-10 were the major polyamine and the major respiratory quinone, respectively. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, sphingoglycolipid, two unidentified lipids and an unidentified aminophospholipid. The major fatty acids were summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c), C16 : 0 and C17 : 1  ω6c. The genome of strain XS-10T consisted of a 4 154 291 bp chromosome with a DNA G+C content of 65.5 mol%. The average nucleotide identity, average amino acid identity and digital DNA-DNA hybridization values of strain XS-10T with S. turrisvirgatae MCT13T and S. koreensis JSS-26T were 77.8 and 78.6 %, 75.9 and 76.3 %, and 22.0 and 22.9 %, respectively. Based on the phylogenetic, phenotypic, and genotypic characteristics, strain XS-10T is considered to represent a novel species of the genus Sphingomonas, for which the name Sphingomonas suaedae sp. nov. is proposed. The type strain is XS-10T (=CGMCC 1.17078T=JCM 33850T).
