“…The polar lipids of strain 3B26 T contained phosphatidylethanolamine (PE), phosphatidylglycerol (PG), and phospholipid (PL) (Supplementary Figure S2). The polar lipid profile of strain 3B26 T was similar to those of S. zhangzhouensis FJAT-52072 T [12] and S. jiangmenensis JM162201 T [10] in that PE and PG were the main components. Strain 3B26 T simultaneously included both ubiquinones (Q-7 and Q-8, 63.6% and 36.4%) and menaquinones (MK-7 and MMK7, 79.9% and 20.1%), which was in line with related reference type strains within the genus Shewanella [9,10].…”

“…Strain 3B26 T was maintained in 25% (v/v) glycerol suspension at −80 • C for long-term preservation. The most closely related type strains, Shewanella amazonensis SB2B T (=CIP 105786 T ) [8], Shewanella litorisediminis SMK1-12 T (=KCTC 23961 T ) [9], and Shewanella jiangmenensis JM162201 T (=GDMCC 1.2006 T ) [10], were obtained from the Institut Pasteur Collection (Paris, France), the Korean Collection for Type Cultures (Jeongeupsi, Korean), and the Guangdong Microbial Culture Collection Center (Guangzhou, China), respectively. Given national regulations on the import and export of pathogens, the type strain Shewanella khirikhana TH2012 T , as a shrimp pathogen, currently cannot be obtained from culture collections or authors, and thus, its taxonomic data were acquired based on species identification [11].…”

“…Visible colonies of strain 3B26 T were light-yellow-colored on MA for 48 h when incubated at 30 • C, and its cells were observed to be straight or curved in a rod shape and motile by means of a single polar flagellum (Figure 1). As shown in Table 1, the colony colors of strain 3B26 T and its relatives were significantly different and thus could be used as a simple indicator to distinguish them [8][9][10][11][12]. The cell growth of strain 3B26 T was found to occur at 10-40 • C (optimum, 28 • C) and at pH 4.0-9.0 (optimum, 7).…”

A new, facultatively anaerobic, light-yellow, and rod-shaped bacterium designated as 3B26T isolated from Qi’ao Island’s tidal flat sediment was identified. Strain 3B26T can hydrolyze gelatin, aesculin, and skim milk. The major cellular fatty acids were identified as iso-C15:0, referred to as summed feature 3, and C16:0; the polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol, and phospholipid; and the quinones contained Q-7, Q-8, MK-7, and MMK7. The genomic size of strain 3B26T was 4,682,650 bp, and its genomic DNA G + C content was 54.8%. While a 16S rRNA gene-based phylogenetic analysis confirmed that strain 3B26T belongs to the genus Shewanella, both phylogenomic inference and genomic comparison revealed that strain 3B26T is distinguishable from its relatives, and digital DNA-DNA hybridization (dDDH) values of 24.4–62.6% and average nucleotide identities (ANIs) of 83.5–95.6% between them were below the 70% dDDH and 96% ANI thresholds for bacterial species delineation. Genomic functional analysis demonstrated that strain 3B26T possesses complete gene clusters of eicosapentaenoic acid biosynthesis and denitrification. Based on the evidence above, strain 3B26T is considered to represent a novel species of the genus Shewanella, and the name Shewanella zhuhaiensis sp. nov. (type strain 3B26T = GDMCC 1.2057T = KCTC 82339T) is proposed.

“…Some Shewanella species isolated from the ocean can thrive under 0%–10% NaCl (w/v) conditions ( Kuribayashi et al, 2017 ; Song et al, 2022 ; Zhang et al, 2022 ). Simliarly, CQ-Y1 grows well within a wide NaCl range of 0 to 10% (w/v).…”

Growth and genome-based insights of Fe(III) reduction of the high-temperature and NaCl-tolerant Shewanella xiamenensis from Changqing oilfield of China

IntroductionA facultative anaerobe bacterium Shewanella xiamenensis CQ-Y1 was isolated from the wastewater of Changqing oilfield in Shaanxi Province of China. Shewanella is the important dissimilatory metal-reducing bacteria. It exhibited a well potential application in biodegradation and bioremediation.MethodsGenome sequencing, assembling and functional annotation were conducted to explore the genome information of CQ-Y1. The effect of temperatures and NaCl concentrations on the CQ-Y1 growth and Fe(III) reduction were investigated by UV visible spectrophotometry, SEM and XRD.ResultsGenomic analysis revealed its complete genome was a circular chromosome of 4,710,887 bp with a GC content of 46.50% and 4,110 CDSs genes, 86 tRNAs and 26 rRNAs. It contains genes encoding for Na+/H+ antiporter, K+/Cl− transporter, heat shock protein associated with NaCl and high-temperature resistance. The presence of genes related to flavin, Cytochrome c, siderophore, and other related proteins supported Fe(III) reduction. In addition, CQ-Y1 could survive at 10% NaCl (w/v) and 45°C, and temperature showed more pronounced effects than NaCl concentration on the bacterial growth. The maximum Fe(III) reduction ratio of CQ-Y1 reached 70.1% at 30°C without NaCl, and the reduction reaction remained active at 40°C with 3% NaCl (w/v). NaCl concentration was more effective than temperature on microbial Fe(III) reduction. And the reduction products under high temperature and high NaCl conditions were characterized as Fe3(PO4)2, FeCl2 and Fe(OH)2.DiscussionAccordingly, a Fe(III) reduction mechanism of CQ-Y1 mediated by Cytochrome c and flavin was hypothesised. These findings could provide information for a better understanding of the origin and evolution of genomic and metabolic diversity of S. xiamenensis.
