“…Our detailed genome-based identification of L. amnigena genomes (n=20 isolates; n=3 MAGs) downloaded from GenBank highlighted misclassification problems with four of the genomes, including that of a proposed type strain for 'L. steviae' [8] (Fig. 1, Table 2).…”

“…Notable was identification of the proposed type strain of 'L. steviae' [8] as Pseudoalteromonas arabiensis (100 % support). L. jeotgali is an earlier heterotypic synonym of L. aquatilis [9], so we would expect the genomes of these species to share high support scores.…”

“…are Gram-negative, facultatively anaerobic bacteria of the family Enterobacteriaceae. The genus Lelliottia was created to accommodate species distinct from Enterobacter sensu lato based on gyrB, rpoB, infB and atpD gene sequence analyses, and comprises four species with validly published names (Lelliottia amnigena, Lelliottia aquatilis, Lelliottia jeotgali and Lelliottia nimipressuralis) and one with a non-valid name ('Lelliottia steviae') [5][6][7][8]. Lelliottia aquatilis represents a later heterotypic synonym of L. jeotgali, based on average nucleotide identity (ANI) and in silico DNA-DNA hybridization analyses [9].…”

Strain M1325/93/1 (herein referred to by our laboratory identifier, GFKo1) of Lelliottia amnigena was isolated from the lung of a harbour porpoise in 1993. The genome sequence and antimicrobial resistance profile (genomic, phenotypic) of the strain were generated, with the genomic data compared with those from closely related bacteria. We demonstrate that the recently described chromosomally encoded AmpC β-lactamase bla LAQ is a core gene of L. amnigena , and suggest that new variants of this class of lactamase are encoded by other members of the genus Lelliottia . Although presence of bla LAQ is ubiquitous across the currently sequenced members of L. amnigena , we highlight that strain GFKo1 is sensitive to ampicillin and cephalosporins. These data suggest that bla LAQ may act as a useful genetic marker for identification of L. amnigena strains, but its presence may not correlate with expected phenotypic resistances. Further studies are required to determine the regulatory mechanisms of bla LAQ in L. amnigena .

“…To determine the optimal pH and growth range, MB was used and adjusted to pH 5.0–10 (0.5 pH units interval) by adding 2-( N -morpholino) ethane sulfonic acid (pH 5.0–5.5), 3-morpholinopropanesulfonic acid (pH 6.0–7.5), tricine buffer (pH 8.0–8.5) and N -cyclohexyl-3-aminopropanesulfonic acid (pH 9.0–10.0) as buffers, respectively [34]. Tolerance to different NaCl concentrations (0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 6.0, 8.0, 10.0 and 12.0 %, w/v) was tested in NaCl-free MB, which was prepared according to the MB formula but without NaCl [35]. All tests above were checked by measurement at the optical density at 600 nm (OD 600nm ) using the UV/visible spectrophotometer (UV756RT, Yoke Instrument).…”

A Gram-stain-negative, strictly aerobic and rod- to coccoid-shaped bacterium, designated as strain M366T, was isolated from coastal sediment of Jiaoshanjiao, Zhejiang Province, PR China (121°54′ E 29 °38′ N). The draft genome of strain M366T was 3 225 479 bp long (with 55.6 mol% G+C content) and assembled into four contigs. The N50 value was 563 270 bp and the genomic completeness and contamination were estimated to be 99.34 and 0.05 %, respectively. Colonies of strain M366T were yellow-orange, 1 mm in diameter, round, opaque, smooth and convex after incubation on marine agar at 30 °C for 3 days. Cells were catalase-positive but oxidase-negative. Strain M366T was observed to grow at 20–40 °C (optimum, 30 °C), pH 5.5–9.0 (optimum, pH 6.5–7.0) and with 0.5–8.0 % (w/v) NaCl (optimum, 2.5 %). Strain M366T shown highest 16S rRNA gene sequence similarity of 98.1 % to Robiginitalea sediminis O458T, 95.6–95.9 % to other type strains of the genus Robiginitalea and below 93 % to other genera. The average nucleotide identity and digital DNA–DNA hybridization values between strain M366T and its closely related Robiginitalea species were 71.1–75.9 % and 17.5–19.0 %. Menaquinone-6 was the only respiratory quinone. The major fatty acids (>10 %) were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 1 (iso-C15 : 1 h and/or C13 : 0 3-OH). The main polar lipids included phosphatidylethanolamine, two unidentified phospholipid, two unidentified aminophospholipid, one unidentified glycolipid and five unidentified lipids. According to the above results, Robiginitalea aestuariiviva sp. nov. is proposed and the type strain is M366T (=KCTC 92866T=MCCC 1K04524T=CGMCC 1.61708T).
