Abstract
In the present work, we characterized in detail strain CM-3-T8T, which was isolated from the rhizosphere soil of strawberries in Beijing, China, in order to elucidate its taxonomic position. Cells of strain CM-3-T8T were Gram-negative, non-spore-forming, aerobic, short rod. Growth occurred at 25-37 °C, pH 5.0-10.0, and in the presence of 0-8% (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain CM-3-T8T formed a stable clade with Lysobacter soli DCY21T and Lysobacter panacisoli CJ29T, with the 16S rRNA gene sequence similarities of 98.91% and 98.50%. The average nucleotide identity and digital DNA-DNA hybridization values between strain SG-8 T and the two reference type strains listed above were 76.3%, 79.6%, and 34.3%, 27%, respectively. The DNA G + C content was 68.4% (mol/mol). The major cellular fatty acids were comprised of C15:0 iso (36.15%), C17:0 iso (8.40%), and C11:0 iso 3OH (8.28%). The major quinone system was ubiquinone Q-8. The major polar lipids were phosphatidylethanolamine (PE), phosphatidylethanolamine (PME), diphosphatidylglycerol (DPG), and aminophospholipid (APL). On the basis of phenotypic, genotypic, and phylogenetic evidence, strain CM-3-T8T (= ACCC 61714 T = JCM 34576 T) represents a new species within the genus Lysobacter, for which the name Lysobacter changpingensis sp. nov. is proposed.

Abstract
Microbial exopolysaccharides (EPSs) have attracted attention from several fields due to their high industrial applicability. In the present study, rhizosphere strain CJ11T was isolated from the root of Glycine max L. in Goyang-si, Republic of Korea, and a novel exopolysaccharide was purified from the Lysobacter sp. CJ11T fermentation broth. The exopolysaccharide's average molecular weight was 0.93 × 105 Da. Its monosaccharide composition included 72.2% mannose, 17.2% glucose, 7.8% galactose, and 2.8% arabinose. Fourier-transform infrared spectroscopy identified the exopolysaccharide carbohydrate polymer functional groups, and the structural properties were investigated using nuclear magnetic resonance. In addition, a microstructure of lyophilized EPS was determined by scanning electron microscopy. Using thermogravimetric analysis, the degradation of the exopolysaccharide produced by strain CJ11T was determined to be 210 °C. The exopolysaccharide at a concentration of 4 mg/mL exhibited 2,2-diphenyl-1-picrylhydrazyl free-radical-scavenging activity of 73.47%. Phylogenetic analysis based on the 16S rRNA gene sequencing results revealed that strain CJ11T was a novel isolate for which the name Lysobacter soyae sp. nov is proposed.

Abstract
A novel bacterial strain, TLK-CK17T, was isolated from cow dung compost sample. The strain was Gram-staining negative, non-gliding rods, aerobic, and displayed growth at 15-40 °C (optimally, 35 °C), with 0-5.0% (w/v) NaCl (optimally, 0.5) and at pH 6.5-8.5 (optimally, 7.0-7.5). The assembled genome of strain TLK-CK17T has a total length of 4.3 Mb with a G + C content of 68.2%. According to the genome analysis, strain TLK-CK17T encodes quite a few glycoside hydrolases that may play a role in the degradation of accumulated plant biomass in compost. On the basis 16S rRNA gene sequence analysis, strain TLK-CK17T showed the highest sequence similarity (98.9%) with L. penaei GDMCC 1.1817 T, followed by L. maris KCTC 42381 T (98.3%). Cells contained iso-C16:0, iso-C15:0, and summed feature 9 (comprising C17:1 ω9c and/or 10-methyl C16:0), as its major cellular fatty acids (> 10.0%) and ubiquinone-8 as the exclusively respiratory quinone. Diphosphatidylglycerol, phosphatidylethanolamine, and phosphatidylglycerol prevailed among phospholipids. Based on the phenotypic, genomic and phylogenetic data, strain TLK-CK17T represents a novel species of the genus Lysobacter, for which the name Lysobacter chinensis sp. nov. is proposed, and the type strain is TLK-CK17T (= CCTCC AB2021257T = KCTC 92122 T).

Post-reclamation microbial diversity and functions in hexachlorocyclohexane (HCH) contaminated soil in relation to spontaneous HCH tolerant vegetation. THE SCIENCE OF THE TOTAL ENVIRONMENT 2021; 767:144653. [PMID: 33550064 DOI: 10.1016/j.scitotenv.2020.144653] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/04/2020] [Revised: 11/24/2020] [Accepted: 12/16/2020] [Indexed: 06/12/2023]
Abstract
The toxicity, volatility and persistence of the obsolete organochlorine pesticide hexachlorocyclohexane (HCH), makes reclamation of contaminated areas a priority for the health and welfare of neighboring human communities. Microbial diversity and functions and their relation to spontaneous vegetation in post-excavation situations, are essential indicators to consider in bioaugmentation or microbe-assisted phytoremediation strategies at field scale. Our study aimed to evaluate the effects of long-term HCH contamination on soil and plant-associated microbial communities, and whether contaminated soil has the potential to act as a bacterial inoculum in post-excavation bioremediation strategies. To scrutinize the role of vegetation, the potential nitrogen fixation of free-living and symbiotic diazotrophs of the legume Lotus tenuis was assessed as a measure of nutrient cycling functions in soil under HCH contamination. Potential nitrogen fixation was generally not affected by HCH, with the exception of lower nifH gene counts in excavated contaminated rhizospheres, most probably a short-term HCH effect on early bacterial succession in this compartment. HCH shaped microbial communities in long-term contaminated bulk soil, where we identified possible HCH tolerants such as Sphingomonas and Altererythrobacter. In L. tenuis rhizosphere, microbial community composition was additionally influenced by plant growth stage. Sphingobium and Massilia were the bacterial genera characteristic for HCH contaminated rhizospheres. Long-term HCH contamination negatively affected L. tenuis growth and development. However, root-associated bacterial community composition was driven solely by plant age, with negligible HCH effect. Results showed that L. tenuis acquired possible HCH tolerant bacteria such as the Allorhizobium-Neorhizobium-Pararhizobium-Rhizobium clade, Sphingomonas, Massilia or Pantoea which could simultaneously offer plant growth promoting (PGP) benefits for the host. Finally, we identified an inoculum with possibly HCH tolerant, PGP bacteria transferred from the contaminated bulk soil to L. tenuis roots through the rhizosphere compartment, consisting of Mesorhizobium loti, Neorhizobium galegae, Novosphingobium lindaniclasticum, Pantoea agglomerans and Lysobacter bugurensis.

Abstract
A polyphasic taxonomic study was carried out on strains CHu50b-3-2T and CHu40b-3-1 isolated from a 67 cm-long sediment core collected from the Daechung Reservoir at a water depth of 17 m, Daejeon, Republic of Korea. The cells of the strains were Gram-stain-negative, non-spore-forming, non-motile and rod-shaped. Comparative 16S rRNA gene sequence studies showed a clear affiliation of two strains with γ-Proteobacteria, which showed the highest pairwise sequence similarities to
Lysobacter hankyongensis
KTce-2T (96.5 %),
Lysobacter pocheonensis
Gsoil193T (96.3 %),
Lysobacter ginsengisoli
Gsoil 357T (96.1 %),
Lysobacter solanacearum
T20R-70T (96.1 %),
Lysobacter brunescens
KCTC 12130T (95.4 %) and
Lysobacter capsici
YC5194T (95.3 %). The phylogenetic analysis based on 16S rRNA gene sequences showed that the strains formed a clear phylogenetic lineage with the genus
Lysobacter
. The major fatty acids were identified as summed feature 9 (iso-C17 : 1
ω9c and/or C18 : 1 10-methyl), iso-C15 : 0, iso-C16 : 0 and iso-C17 : 0. The respiratory quinone was identified as ubiquinone Q-8. The major polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and an unidentified phospholipid. The genomic DNA G+C content was determined to be 66.8 mol% (genome) for strain CHu50b-3-2T and 66.4 mol% (HPLC) for strain CHu40b-3-1. Based on the combined genotypic and phenotypic data, we propose that strains CHu50b-3-2T and CHu40b-3-1 represent a novel species of the genus
Lysobacter
, for which the name Lysobacter profundi sp. nov. is proposed. The type strain is CHu50b-3-2T (=KCTC 72973T=CCTCC AB 2019129T). Besides
Lysobacter panaciterrae
Gsoil 068T formed a phylogenetic group together with strain
Luteimonas aquatica
RIB1-20T (EF626688) that is clearly separated from all other known
Lysobacter
strains. Based on the phylogenetic relationships together with fatty acid compositions,
Lysobacter panaciterrae
Gsoil 068T should be reclassified as a member of the genus Luteimonas: Luteimonas aquatica comb. nov. (type strain Gsoil 068T=KCTC 12601T=DSM 17927T).

Abstract
A bacterial strain isolated from a soil collected in Jeju Island, designated as 17J7-1T, was Gram-negative, rod-shaped, yellow colored, and motile by gliding. This strain was able to grow at temperature range from 10 to 42 °C, pH 7-9, and tolerated up to 1% NaCl. Analysis of 16S rRNA sequence identified strain 17J7-1T as a member of the genus Lysobacter with close sequence similarity with Lysobacter mobilis 9NM-14T (97.4%), Lysobacter xinjiangensis RCML-52T (97.0%), and Lysobacter humi FJY8T (96.9%). The genomic DNA G + C content of the isolate was 67.9 mol%. DNA-DNA relatedness between strain 17J7-1T and L. mobilis, L. humi, and L. xinjiangensis were 42.3%, 39.5%, and 35.8%, respectively, clearly showing that the isolate is distinct from its closest phylogenetic neighbors in the genus Lysobacter. Average nucleotide identity (ANI) and digital DNA-DNAhybridization (dDDH) values between strain 17J7-1T and L. enzymogenes ATCC 29487T, the type species of this genus, and several other close Lysobacter species were less than 77% and 22%, respectively. Major fatty acids were C16:0 iso (29.8%), summed feature 9 (C17:1 iso ω9c/C16:0 10-methyl; 20.1%), and C15:0 iso (17.7%). The predominant respiratory quinone was ubiquinone Q-8 and the major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, and diphosphatidylglycerol. In the light of the polyphasic evidence accumulated in this study, strain 17J7-1T is considered to represent a novel species in the genus Lysobacter, for which name Lysobacter terrigena sp. nov. is proposed. The type strain is 17J7-1T (= KCTC 62217T = JCM 33057T).

Abstract
A Gram-stain negative, rod-shaped bacterial, catalase and oxidase positive strain (83-4T) that formed yellow colonies was isolated from human Meibomian gland secretions. Strain 83-4T belongs to the genus Lysobacter according to phylogenetic analysis based on 16S rRNA gene sequences. The DNA G+C content was 67.1 mol%. The circular genome was 2.6 Mb, which contained 2431 protein-coding sequences, 75 pseudogenes, 46 tRNAs, 3 rRNAs and 4 ncRNAs. A bacteriocin cluster and aryl polyene cluster were also found in the genome. The average nucleotide identity value was 79.6% between isolate 83-4T and the closely related type strain Lysobacter tolerans UM1T. The estimated DNA-DNA hybridization value between strain 83-4T and L. tolerans UM1T was 41.6%. Diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol were the major polar lipids. Iso-C15:0, iso-C11:0 3-OH, iso-C11:0 and summed feature 9 (iso-C17:1ω9c) were the major fatty acids. Ubiquinone (Q-8) was the only respiratory quinone. Therefore, based on the data of phylogenetic analysis, chemotaxonomical and biochemical analyses, it is concluded that strain 83-4T represents a novel species of the genus Lysobacter with the name of Lysobacter oculi sp. nov. The type strain is 83-4T (= CGMCC 1.13464T = NRBC 113451T).

The bacterial strains 4284/11T and 812/17 isolated from the respiratory tract of two royal pythons in 2011 and 2017, respectively were subjected to taxonomic characterization. The 16S rRNA gene sequences of the two strains were identical and showed highest sequence similarities to Lysobacter tolerans UM1T (97.2%) and Luteimonas aestuarii DSM 19680T (96.7 %). The two strains were identical in the sequences of the 16S-23S rRNA internal transcribed spacer (ITS) and partial groEL gene sequences and almost identical in genomic fingerprints. In the ITS sequence Ly. tolerans DSM 28473T and in the groEL nucleotide sequence Luteimonas mephitis DSM 12574T showed the highest similarity. In silico DDH analyses using genome sequence based ANIb and gANI similarity coefficients demonstrated that strain 4284/11T represents a novel species and revealed Ly. tolerans UM1T as the next relative (ANIb = 76.2 %, gANI = 78.0 %). Based on the topology of a core gene phylogeny strain 4284/11T could be assigned to the genus Lysobacter. Chemotaxonomic characteristics including polyamine pattern, quinone system, polar lipid profile and fatty acid profile were in accordance with the characteristics of the genera Lysobacter and Luteimonas. Strains 4284/11T and 812/17 could be differentiated from the type strains of the most closely related species by several physiological tests. In conclusion we are here proposing the novel species Lysobacter pythonis sp. nov. The type strain is 4284/11T (= CCM 8829T = CCUG 72164T = LMG 30630T) and strain 812/17 (CCM 8830) is a second strain of this species.
