16S Rrna Gene Sequences

Two sporulating bacterial strains designated CECAP06T and CECAP16 were isolated from the rhizosphere of the legume Cicer arietinum in Argentina. Almost-complete 16S rRNA gene sequences identified the isolates as a Paenibacillus species. It was most closely related to Paenibacillus cineris LMG 18439T (99·6 % sequence similarity), Paenibacillus favisporus LMG 20987T (99·4 % sequence similarity) and Paenibacillus azoreducens DSM 13822T (97·7 % sequence similarity). The cells of this novel species were motile, sporulating, rod-shaped, Gram-positive and strictly aerobic. The predominant fatty acids were anteiso-C15 : 0, C16 : 0 and iso-C16 : 0. The DNA G+C content of strains CECAP06T and CECAP16 was 51·3 and 50·9 mol%, respectively. Growth was observed from many carbohydrates, but gas production was not observed from glucose. Catalase and oxidase activities were present. The isolates produced β-galactosidase and hydrolysed aesculin. Gelatinase, caseinase and urease were not produced. The results of DNA–DNA hybridization showed that the strains from this study constitute a novel species of the genus Paenibacillus, for which the name Paenibacillus rhizosphaerae sp. nov. is proposed. The type strain is CECAP06T (=LMG 21955T=CECT 5831T).

Abstract A Gram-negative, yellow-pigmented, rod-shaped bacterial strain YIM B02567 T was isolated from the root of Paris polyphylla Smith var. yunnanensis in China. Strain YIM B02567 T grew optimally at 25–30°C and at pH 7.0 in the absence of NaCl on nutrient agar. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain YIM B02567 T belong to the genus Chryseobacterium , and closely related to Chryseobacterium piperi CTM T and Chryseobacterium soli DSM 19298 T . Whole genome sequencing indicated that the genome size was 4,774,612 bp and had a DNA G+C content of 34.5 %. Values of the ANI and the dDDH between strain YIM B02567 T and its closely related Chryseobacterium species were below 81.72 % and 24.7 %. Strain YIM B02567 T contained menaquinone-6 as the sole isoprenoid quinone, anteiso-C 15:0, iso-C 17:1 ω 9 c and iso-C 17:0 3-OH as major fatty acids and phosphatidylethanolamine as major polar lipid. Based on the polyphasic analyses, strain YIM B02567 T could be differentiated genotypically and phenotypically from recognized species of the genus Chryseobacterium . The isolate therefore represents a novel species, for which the name Chryseobacterium paridis sp. nov. is proposed. The type strain is YIM B02567 T (=CGMCC 1.18657 T =JCM 5426 T ).

A novel actinobacterium, designated strain C4-31T, was isolated from soil collected from a cave. Cells were aerobic, Gram-reaction-positive, oxidase-negative, catalase-positive and non-motile cocci. Comparison of 16S rRNA gene sequences showed that the organism occupied a distinct phylogenetic position within the suborder Frankineae, with sequence similarity values of less than 93.2 % to members of this suborder. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. The major menaquinone was MK-9(H4). The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside, an unknown aminophospholipid and an unknown phospholipid. The major fatty acids were iso-C16 : 0, C17 : 1ω6c and C16 : 0. The G+C content of the DNA was 62.8 mol%. On the basis of morphological and chemotaxonomic data as well as phylogenetic evidence, strain C4-31T ( = KCTC 39556T = DSM 100065T) is considered to represent the type strain of a novel species of a new genus in the suborder Frankineae, for which the name Antricoccus suffuscus gen. nov., sp. nov. is proposed.

Two bacterial strains, designated GH34-4T and GH41-7T, were isolated from greenhouse soil cultivated with cucumber. The bacteria were strictly aerobic, Gram-negative, rod-shaped and oxidase- and catalase-positive. 16S rRNA gene sequence analysis indicated that these strains belong to the genus Lysobacter within the Gammaproteobacteria. Strain GH34-4T showed highest sequence similarity to Lysobacter yangpyeongensis GH19-3T (97.5 %) and Lysobacter koreensis Dae16T (96.4 %), and strain GH41-7T showed highest sequence similarity to Lysobacter antibioticus DSM 2044T (97.5 %), Lysobacter enzymogenes DSM 2043T (97.5 %) and Lysobacter gummosus ATCC 29489T (97.4 %). Levels of DNA–DNA relatedness indicated that strains GH34-4T and GH41-7T represented species clearly different from L. yangpyeongensis, L. antibioticus, L. enzymogenes and L. gummosus. The major cellular fatty acids of strains GH34-4T and GH41-7T were iso-C16 : 0, iso-C15 : 0 and iso-C17 : 1 ω9c, and the major isoprenoid quinone was Q-8. The DNA G+C contents of GH34-4T and GH41-7T were 62.5 and 66.6 mol%, respectively. On the basis of the polyphasic taxonomic data presented, it is evident that each of these strains represents a novel species of the genus Lysobacter, for which the names Lysobacter niabensis sp. nov. (type strain GH34-4T=KACC 11587T=DSM 18244T) and Lysobacter niastensis sp. nov. (type strain GH41-7T=KACC 11588T=DSM 18481T) are proposed.
