Lysobacter panaciterrae sp. nov., isolated from soil of a ginseng field.
International journal of systematic and evolutionary microbiology, 2009Co-Authors: Leonid N. Ten, Hae-min Jung, Soon-ae Yoo, Sungtaik LeeAbstract:A Gram-negative, aerobic, rod-shaped, non-spore-forming bacterial strain, designated Gsoil 068(T), was isolated from soil of a ginseng field in Pocheon Province (South Korea), and was characterized to determine its taxonomic position by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain Gsoil 068(T) belonged to the family Xanthomonadaceae, class Gammaproteobacteria, and was related most closely to Lysobacter brunescens ATCC 29482(T) and Lysobacter gummosus ATCC 29489(T) (96.1 % sequence similarity). The G+C content of the genomic DNA of strain Gsoil 068(T) was 67.0 mol%. The detection of a quinone system with ubiquinone Q-8 as the predominant component and a fatty acid profile with iso-C(15 : 0), iso-C(17 : 1)omega9c, iso-C(17 : 0) and iso-C(11 : 0) 3-OH as the major components supported the affiliation of strain Gsoil 068(T) to the genus Lysobacter. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil 068(T) is considered to represent a novel species of the genus Lysobacter, for which the name Lysobacter panaciterrae sp. nov. is proposed. The type strain is Gsoil 068(T) (=KCTC 12601(T) =DSM 17927(T)).

Lysobacter daecheongensis sp. nov., isolated from sediment of stream near the Daechung dam in South Korea.
Journal of microbiology (Seoul Korea), 2008Co-Authors: Leonid N. Ten, Hae-min Jung, Soon-ae Yoo, Sungtaik LeeAbstract:A Gram-negative, aerobic, rod shaped, non-spore-forming bacterial strain, designated Dae08T, was isolated from sediment of the stream near Daechung dam in South Korea, and was characterized in order to determine its taxonomic position, using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain Dae08T belongs to the family Xanthomonadaceae of the Gammaproteobacteria, and is related to Lysobacter brunescens ATCC 29482T (97.3%). The phylogenetic distances from any other species with validly published names within the genus Lysobacter were greater than 3.7%. The G+C contents of the genomic DNA of strain Dae08T was 69.3 mol%. The detection of a quinone system with Q-8 as the predominant compound and a fatty acid profile with iso-C15:0, iso-C17:1, ω9c, iso-C17:0, iso-C16:0, and iso-C11:0 3-OH as the major acids supported the affiliation of strain Dae08T to the genus Lysobacter. DNA-DNA relatedness between strain Dae08T and its phylogenetically closest neighbour was 28%. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Dae08T (= KCTC 12600T) should be classified in the genus Lysobacter as the novel species, for which the name Lysobacter daecheongensis sp. nov. is proposed.

Lysobacter concretionis sp nov isolated from anaerobic granules in an upflow anaerobic sludge blanket reactor
International Journal of Systematic and Evolutionary Microbiology, 2005Co-Authors: Heesung Bae, Sungtaik LeeAbstract:The taxonomic positions of Lysobacter species with validly published names and a novel strain Ko07T, which was newly isolated from an upflow anaerobic sludge blanket reactor treating wastewater from a brewery, were (re)estimated on the basis of results obtained by using a polyphasic taxonomy approach. Phylogenetic inference based on 16S rRNA gene sequences showed that strain Ko07T and all Lysobacter species with validly published names clustered together in a phylogenetic branch within the class ‘Gammaproteobacteria’. The sequence similarity of strain Ko07T to the type strains of established Lysobacter species was in the range 94·9–96·7 %. Ubiquinone Q-8 and branched fatty acids, C11 : 0 iso, C15 : 0 iso, C16 : 0 iso, iso C17 : 1 ω9c and C11 : 0 iso 3OH, predominantly appeared in strain Ko07T as well as in all type strains of the recognized Lysobacter species. The DNA–DNA hybridization values of strain Ko07T with those of recognized Lysobacter species were estimated to be 2–20 %. Despite sharing common taxonomic features in important phenotypic characteristics, such as gliding movement, long-rod shape and proteolytic activity, strain Ko07T could be distinguished from the Lysobacter species with validly published names by its low DNA–DNA hybridization value, a comparatively low DNA G+C content (63·8 mol%), substrate utilization and some physiochemical characteristics. On the basis of the results obtained in this study, it is proposed that strain Ko07T should be classified as representing a novel member of the genus Lysobacter, for which the name Lysobacter concretionis sp. nov. is proposed. The type strain is Ko07T (=KCTC 12205T=DSM 16239T).

Lysobacter oryzae sp nov isolated from the rhizosphere of rice oryza sativa l
International Journal of Systematic and Evolutionary Microbiology, 2009Co-Authors: Zubair Aslam, Muhammad Yasir, Che Ok Jeon, Young Ryun ChungAbstract:The taxonomic position of a novel bacterial strain, YC6269T, isolated from the rhizosphere of rice (Oryza sativa L.) managed under no-tillage practice in Jinju, South Korea, was studied using polyphasic approach. Cells of the strain were Gram-negative, rod-shaped and facultatively anaerobic. The novel strain grew at a temperature of 15–42 °C (optimum at 28 °C). Growth of the strain occurred between pH 5.5 and 11.0, with an optimum at pH 7.0–8.0. The G+C content of the total DNA was 67.4 mol%. The 16S rRNA gene sequence of the strain was most closely related to species of the genus Lysobacter, Lysobacter yangpyeongensis DSM 17635T (98.6 %), Lysobacter niabensis GH34-4T (97.2 %), Lysobacter enzymogenes DSM 2043T (96.9 %), Lysobacter daejeonensis DSM 17634T (96.3 %) and Lysobacter niastensis GH41-7T (96.2 %). The novel strain showed <96.0 % similarity with other species of the genus Lysobacter. Chemotaxonomic data (major quinone, Q-8; major polar lipids, phosphatidylethanolamine, phosphatidylglycerol and phosphatidyl-N-methylethanolamine, and major fatty acids, C15 : 0 iso, C16 : 0 iso, C17 : 0 iso and C17 : 1 iso ω9c) supported the affiliation of strain YC6269T to the genus Lysobacter. Phylogenetic analysis based on the 16S rRNA gene sequences, DNA–DNA hybridization data and biochemical and physiological characteristics strongly supported the genotypic and phenotypic differentiation of strain YC6269T from recognized species of the genus Lysobacter. Strain YC6269T, therefore, represents a novel member of the genus Lysobacter, for which the name Lysobacter oryzae sp. nov. is proposed. The type strain is YC6269T (=KCTC 22249T=DSM 21044T).

The 16S rRNA gene sequence of the strain was most closely related to species of the genus Lysobacter, Lysobacter yangpyeongensis DSM 17635T (98.6 %), Lysobacter niabensis GH34-4T (97.2 %), Lysobacter enzymogenes DSM 2043T (96.9 %), Lysobacter daejeonensis DSM 17634T (96.3 %) and Lysobacter niastensis GH41-7T (96.2 %). The novel strain showed <96.0 % similarity with other species of the genus Lysobacter. Chemotaxonomic data (major quinone, Q-8; major polar lipids, phosphatidylethanolamine, phosphatidylglycerol and phosphatidyl-N-methylethanolamine, and major fatty acids, C15 : 0 iso, C16 : 0 iso, C17 : 0 iso and C17 : 1 iso ω9c) supported the affiliation of strain YC6269T to the genus Lysobacter. Phylogenetic analysis based on the 16S rRNA gene sequences, DNA–DNA hybridization data and biochemical and physiological characteristics strongly supported the genotypic and phenotypic differentiation of strain YC6269T from recognized species of the genus Lysobacter. Strain YC6269T, therefore, represents a novel member of the genus Lysobacter, for which the name Lysobacter oryzae sp. nov. is proposed. The type strain is YC6269T (=KCTC 22249T=DSM 21044T).

International journal of systematic and evolutionary microbiology, 2008Co-Authors: Joo Hwang Park, Zubair Aslam, Che Ok Jeon, Rumi Kim, Young Ryun ChungAbstract:The taxonomic position of a novel bacterial strain, YC5194(T), with antimicrobial activity, isolated from the rhizosphere of pepper in Jinju, South Korea, was studied using a polyphasic approach. Cells of the strain were Gram-negative, rod-shaped, facultative anaerobes. It grew at a temperature of 15-37 degrees C (optimum 28 degrees C). Growth of the strain occurred between pH 5.5 and 8.5, with an optimum of pH 7.0-7.5. The strain inhibited mycelial growth of Pythium ultimum, Colletotrichum gloeosporioides, Fusarium oxysporum, Botrytis cinerea, Rhizoctonia solani and Botryosphaeria dothidea and growth of Bacillus subtilis. The G+C content of the total DNA was 65.4 mol%. The 16S rRNA gene sequence of the strain was most closely related to species of the genus Lysobacter (99.0 % sequence similarity). Chemotaxonomic data (major quinone, Q-8; major polar lipids, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and phosphatidyl-N-methylethanolamine; major fatty acids, iso-C(15 : 0), summed feature 3, C(16 : 0), iso-C(17 : 1)omega9c and C(18 : 1)omega7c) supported the affiliation of strain YC5194(T) to the genus Lysobacter. Phylogenetic analysis based on 16S rRNA gene sequences, DNA-DNA hybridization data and biochemical and physiological characteristics strongly supported the genotypic and phenotypic differentiation of strain YC5194(T) from species of Lysobacter with validly published names. Strain YC5194(T) therefore represents a novel species, for which the name Lysobacter capsici sp. nov. is proposed. The type strain is YC5194(T) (=KCTC 22007(T) =DSM 19286(T)).
