ABSTRACT
A Gram-stain-negative and facultatively anaerobic bacterial strain designated as JM162201T was isolated from aquaculture water for farming Pacific white shrimp (Litopenaeus vannamei). The genome size of strain JM162201T was 4,436,316 bp, and the genomic DNA G + C content was 55.0%. Phylogenetic analysis based on 16S rRNA gene sequences and genomes showed that strain JM162201T belonged to the genus Shewanella and was closely related to Shewanella litorisediminis SMK1-12T (97.1%), Shewanella khirikhana TH2012T (97.0%), and Shewanella amazonensis SB2BT (96.0%). The average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values between strain JM162201T and three reference type strains were below the recognized thresholds of 95.0-96.0% (for ANI) and 70.0% (for dDDH) for species delineation. Growth occurred at 10-40 °C (optimum, 30 °C), at pH 4.0-10.0 (optimum, 7.0-8.0), and in 0-6.0% NaCl (w/v, optimum, 0-0.1%). The major cellular fatty acids of strain JM162201T were summed feature 3 (C161 ω7c and/or C161 ω6c), C171 ω8c, iso-C150, C160, and C150. The predominant quinones were MK7, Q-7, and Q-8. The major polar lipids were phosphatidylethanolamine (PE) and phosphatidylglycerol (PG). Based on the polyphasic taxonomical analyses, strain JM162201T represents a novel species of the genus Shewanella, for which the name Shewanella jiangmenensis sp. nov. is proposed, with the type strain JM162201T (= GDMCC 1.2006T = KCTC 82340T).
