| labrys methylaminiphilus sp. nov., a novel facultatively methylotrophic bacterium from a freshwater lake sediment. | a new bacterial isolate from a methylamine enrichment culture is described, representing a novel species of facultatively methylotrophic bacteria. the non-motile bacterium is gram-negative, replicates by budding and does not form endospores. the isolate utilizes methylated amines, as well as a variety of monosaccharides, disaccharides, amino acids, organic acids, aromatic compounds and alcohols as substrates, but does not utilize methanol. growth factors are not required, although yeast extract ... | 2005 | 15879264 |
| the hierarchical system of the 'alphaproteobacteria': description of hyphomonadaceae fam. nov., xanthobacteraceae fam. nov. and erythrobacteraceae fam. nov. | phylogenetic analysis of the class 'alphaproteobacteria', including physiologically diverse species, was conducted by using small-subunit rrna gene sequences. the 16s rrna gene sequences of 261 species in the class 'alphaproteobacteria' were obtained from genbank/embl/ddbj for constructing a phylogenetic tree by using maximum-likelihood analysis. in the resulting tree, members of the class 'alphaproteobacteria' were subdivided into five major clusters, which were compared with the taxonomic outl ... | 2005 | 16166687 |
| pseudolabrys taiwanensis gen. nov., sp. nov., an alphaproteobacterium isolated from soil. | a gram-negative, short rod-shaped micro-organism (cc-bb4(t)) was isolated on nutrient agar from soil from sinshe in taichung county, taiwan. analysis of the 16s rrna gene sequence demonstrated that this isolate was novel, as it showed <92 % similarity to the sequences of species of the genera labrys, beijerinckia and methylocystis. the micro-organism did not utilize methylamine or methanol as a substrate, but was able to use several organic acids. the fatty acid profile was different from those ... | 2006 | 17012581 |
| labrys okinawensis sp. nov. and labrys miyagiensis sp. nov., budding bacteria isolated from rhizosphere habitats in japan, and emended descriptions of the genus labrys and labrys monachus. | three strains, maff 210191(t), g24103(t) and g24116, assumed to be members of two novel species, were isolated from several rhizosphere habitats in different parts of japan. phylogenetic analysis based on 16s rrna gene sequences revealed that the isolates formed a distinct monophyletic group together with the two known species of the genus labrys, suggesting that the isolates have a close affiliation with this genus. in this study, a polyphasic approach was used to characterize and compare the t ... | 2007 | 17329783 |
| labrys neptuniae sp. nov., isolated from root nodules of the aquatic legume neptunia oleracea. | a bacterium designated strain liujia-146(t) was isolated in the tainan area of southern taiwan from root nodules of the aquatic legume neptunia oleracea. 16s rrna gene sequence analysis indicated that strain liujia-146(t) was highly similar to labrys monachus vkm b-1479(t) (97.8 %) and labrys methylaminiphilus jlw10(t) (95.5 %) and belonged to the order rhizobiales in the alphaproteobacteria. on the basis of phylogenetic analysis, dna-dna hybridization data, physiological and biochemical charact ... | 2007 | 17329788 |
| labrys portucalensis sp. nov., a fluorobenzene-degrading bacterium isolated from an industrially contaminated sediment in northern portugal. | a detailed classification of a novel bacterial strain, designated f11(t), capable of degrading fluorobenzene as a sole carbon and energy source, was performed by using a polyphasic approach. this gram-negative, rod-shaped, non-motile, non-spore-forming, aerobic bacterium was isolated from a sediment sample collected from an industrially contaminated site in northern portugal. the predominant whole-cell fatty acids were c(19 : 0) cyclo omega8c, c(16 : 0), c(18 : 1)omega7c, c(18 : 0), c(18 : 0) 3- ... | 2008 | 18319480 |
| labrys wisconsinensis sp. nov., a budding bacterium isolated from lake michigan water, and emended description of the genus labrys. | two facultatively anaerobic, budding bacterial strains, designated w1215-pca4(t) and srnk-1, were isolated from water from lake michigan, usa. the two strains showed identical eric-pcr-generated genomic fingerprints and shared 99.9 % 16s rrna gene sequence similarity. strain w1215-pca4(t) showed highest 16s rrna gene sequence similarities to labrys monachus vkm b-1479(t) (95.8 %), labrys methylaminiphilus dsm 16812(t) (95.1 %), labrys okinawensis maff 210191(t) (96.0 %), labrys miyagiensis g2410 ... | 2010 | 19684322 |
| impact of cadmium on the bacterial communities in the gut of metaphire posthuma. | the effects of cadmium (cd) contamination in soil onto the bacterial communities of the guts pooled from ten metaphire posthuma were addressed during 14 days' incubation. we found that about 50% of cd (5mg/kg, dry weight soil) in the contaminated soil was bio-accumulated into the earthworms. dna was extracted from the guts of m. posthuma and their dwelling soil irrespective of cd treatment for the analysis of the bacterial communities of guts in m. posthuma and in soil by pcr-dgge (polymerase ch ... | 2009 | 19747774 |
