Mesohalobacter halotolerans gen. nov., sp. nov., isolated from a marine solar saltern

Abstract

<jats:p>A Gram-stain-negative, non-motile, fine rod or short filament shaped, jacinth pigmented bacterium, designated strain WDS2C27<jats:sup>T</jats:sup>, was isolated from a marine solar saltern in Wendeng, Weihai, PR China (37°31′5″ N, 122°1′47″ E). Growth of WDS2C27<jats:sup>T</jats:sup> occurred at 20–42 °C (optimum 37 °C) and pH 6.5–8.5 (optimal pH 7.0–8.0). Optimal growth occurred in modified marine broth containing 6 % (w/v) NaCl. The major polar lipids in WDS2C27<jats:sup>T</jats:sup> were phosphatidylethanolamine, two unidentified aminolipids and one unidentified lipid. The major respiratory quinone of WDS2C27<jats:sup>T</jats:sup> was MK-6. The dominant fatty acids were iso-C<jats:sub>15 : 0</jats:sub> and anteiso<jats:bold>-</jats:bold>C<jats:sub>15 : 0</jats:sub>. The DNA G+C content was 35.0 mol%. The nucleotide sequence of the 16S rRNA gene indicated that the most closely related strain was <jats:italic> <jats:named-content content-type="species"> <jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="http://doi.org/10.1601/nm.27967" xlink:type="simple">Psychroflexus planctonicus</jats:ext-link> </jats:named-content> </jats:italic> X15M-8<jats:sup>T</jats:sup> (92.0 % over 1452 bp). WDS2C27<jats:sup>T</jats:sup> showed 60.7 % average amino acid identity, 55.6 % percentage of conserved proteins, 75.0 % average nucleotide identity and 13.1 % digital DNA–DNA hybridization identity with the type species of the genus <jats:italic> <jats:named-content content-type="genus"> <jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="http://doi.org/10.1601/nm.8182" xlink:type="simple">Psychroflexus</jats:ext-link> </jats:named-content> </jats:italic>, <jats:italic> <jats:named-content content-type="species"> <jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="http://doi.org/10.1601/nm.8183" xlink:type="simple">Psychroflexus torquis</jats:ext-link> </jats:named-content> </jats:italic> ATCC 700755<jats:sup>T</jats:sup>. The phenotypic and genotypic properties and phylogenetic inference indicated that WDS2C27<jats:sup>T</jats:sup> could be assigned to a novel species within a novel genus, for which the name <jats:italic>Mesohalobacter halotolerans</jats:italic> gen. nov., sp. nov. is proposed. Strain WDS2C27<jats:sup>T</jats:sup> (=MCCC 1H00133<jats:sup>T</jats:sup>=KCTC 52044<jats:sup>T</jats:sup>) is the type strain.</jats:p>

Corrigendum: Correction to manuscripts describing the fatty acid composition of organisms submitted to IJSEM between 2014 and 2021

“…The previously published articles listed in the References [1–50] contained the phrase ‘Summed features are groups of two or three fatty acids that are treated together for the purpose of evaluation in the MIDI system and include both peaks with discrete ECLs as well as those where the ECLs are not reported separately’, which was taken from and consequently should have cited the following article:…”
