The 16S rRNA gene sequence analysis revealed that strain RSG39T belonged to the genus Simplicispira in the class Betaproteobacteria and its highest sequence similarity was shared with S. psychrophila (98.4 %). The isolate grew optimally at 20 °C, at pH 7 and with 0 % (w/v) NaCl. The main respiratory quinone of the isolate was ubiquinone Q-8. The major cellular fatty acids were C16 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c). The polar lipids of the isolate were phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol and six unidentified lipids. The DNA–DNA hybridization values showed < 7.4 % genomic relatedness with closely related strains. The genomic DNA G+C content was 65.2 mol %. Based on phylogenetic, phenotypic, chemotaxonomic and genotypic analyses, strain RSG39T represents a novel species of the genus Simplicispira, for which the name Simplocospira piscis sp. nov. is proposed. The type strain is RSG39T ( = KACC 17539T = JCM 19291T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.000635
