| [phylogenetic analysis of aerobic methylotrophic bacteria, using dichloromethane]. | the phylogenetic relationships of 12 aerobic dichloromethane-degrading bacteria that implement different c1-assimilation pathways was determined based on 16s ribosomal rna sequences and dna-dna hybridization data. the restricted facultative methylotroph "methylophilus leisingerii" dm11 with the ribulose monophosphate pathway was found to belong to the genus methylophilus cluster of the beta subdivision of the phylogenetic kingdom proteobacteria. the facultative methylotroph methylorhabdus multiv ... | 2001 | 11338843 |
| starkeya koreensis sp. nov., isolated from rice straw. | a facultatively chemolithoautotrophic, gram-negative, aerobic, highly curved rod-shaped, non-motile, non-spore-forming bacterium, strain jip08(t), was isolated from rice straw in daejeon, south korea. strain jip08(t) produced colourless colonies (1.0-1.5 mm) on r2a medium after 3 days. on the basis of 16s rrna gene sequence similarity, strain jip08(t) was shown to belong to the alpha-2 subclass of the proteobacteria, and was most closely related to starkeya novella iam 12100(t) (98.6 %), angulom ... | 2006 | 17012571 |
| 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 |
| stable carbon isotope fractionation during degradation of dichloromethane by methylotrophic bacteria. | stable carbon isotope fractionation during dichloromethane (dcm) degradation by methylotrophic bacteria was investigated under aerobic and nitrate-reducing conditions. the strains studied comprise several hyphomicrobium strains, methylobacterium, methylopila, methylophilus and methylorhabdus spp. that are considered to degrade dcm by a glutathione (gsh)-dependent dehalogenase enzyme system in the initial step. the stable carbon isotope fractionation factors (alphac) of the strains varied under a ... | 2006 | 16343330 |
| methylarcula marina gen. nov., sp. nov. and methylarcula terricola sp. nov.: novel aerobic, moderately halophilic, facultatively methylotrophic bacteria from coastal saline environments. | a new genus, methylarcula, with two new species, methylarcula marina and methylarcula terricola, are proposed for strains h1t and h37t of moderately halophilic facultatively methylotrophic bacteria isolated from the coastal saline habitats. these methylobacteria are aerobic, gram-negative, asporogenous, non-motile, colourless rods that multiply by binary fission. their cellular fatty acids profiles consist primarily of straight-chain unsaturated (c18:1; 70-80%), saturated (c18:0; 14-16%) and cyc ... | 2000 | 11034496 |
| methylopila capsulata gen. nov., sp. nov., a novel non-pigmented aerobic facultatively methylotrophic bacterium. | a new genus, methylopila, and one new species are described for a group of seven strains of facultatively methylotrophic bacteria with the serine pathway of c1 assimilation. these bacteria are aerobic, gram-negative, non-spore--forming, motile, colourless rods that multiply by binary fission. their dna base content ranges from 66 to 70 mol % g + c. their cellular fatty acid profile consists primarily of c18:1 omega 7 cis-vaccenic and c19:0 cyclopropane acids. the major hydroxy acid is 3-oh c14:0 ... | 1998 | 9828432 |
