| phylogenetic heterogeneity within the genus herpetosiphon: transfer of the marine species herpetosiphon cohaerens, herpetosiphon nigricans and herpetosiphon persicus to the genus lewinella gen. nov. in the flexibacter-bacteroides-cytophaga phylum. | analysis of the 16s rdna sequences of species currently assigned to the genus herpetosiphon revealed intrageneric phylogenetic heterogeneity. the thermotolerant freshwater species herpetosiphon geysericola is most closely related to the type species herpetosiphon aurantiacus in the chloroflexus subdivision of the green non-sulfur bacteria. the marine species herpetosiphon cohaerens, herpetosiphon nigricans and herpetosiphon persicus, on the other hand, were found to form a cluster with sheathed ... | 1998 | 9734027 |
| polyamine distribution profiles in the eighteen genera phylogenetically located within the flavobacterium-flexibacter-cytophaga complex. | cellular polyamines of eighteen genera belonging to the flavobacterium-flexibacter-cytophaga complex were analysed by ion exchange liquid chromatography. homospermidine was the major polyamine in the genera bergeyella, riemerella, ornithobacterium, weeksella, capnocytophaga, polaribacter and psychroflexus belonging to the family flavobacteriaceae. in the family spirosomaceae, runella, spirosoma and flectobacillus species contained spermidine whereas cyclobacterium species contained homospermidin ... | 2001 | 11491527 |
| new degenerate cytophaga-flexibacter-bacteroides-specific 16s ribosomal dna-targeted oligonucleotide probes reveal high bacterial diversity in river taff epilithon. | river microbial communities play an important role in global nutrient cycles, and aggregated bacteria such as those in epilithic biofilms may be major contributors. in this study the bacterial diversity of river taff epilithon in south wales was investigated. a 16s ribosomal dna (rdna) clone library was constructed and analyzed by partial sequencing of 76 of 347 clones and hybridization with taxon-specific probes. the epilithon was found to be very diverse, with an estimated 59.6% of the bacteri ... | 2002 | 11772628 |
| lewinella agarilytica sp. nov., a novel marine bacterium of the phylum bacteroidetes, isolated from beach sediment. | a gram-negative, aerobic, light-orange-coloured, marine bacterium (designated sst-19(t)) was isolated from beach sediment in jeju, korea, and its taxonomic position was determined by means of a polyphasic approach. in a neighbour-joining phylogenetic tree based on 16s rrna gene sequences, strain sst-19(t) was positioned within the family 'saprospiraceae', class sphingobacteria, and formed a consistent cluster with lewinella persica atcc 23167(t) (94.7 % sequence similarity). the levels of 16s rr ... | 2007 | 18048730 |
| emended descriptions of the genus lewinella and of lewinella cohaerens, lewinella nigricans and lewinella persica, and description of lewinella lutea sp. nov. and lewinella marina sp. nov. | two strains, mkg-38(t) and fyk2402m69(t), were isolated from a marine sediment sample and a sea snail, respectively, both collected on the pacific coast of japan. phylogeny of these new isolates based on 16s rrna gene sequences indicated that they are members of the genus lewinella. morphological, physiological and biochemical properties of these two isolates, together with the type strains of the three previously described species of the genus lewinella, were characterized. the new isolates wer ... | 2007 | 18048755 |
| lewinella antarctica sp. nov., a marine bacterium isolated from antarctic seawater. | a marine bacterium, designated imcc3223t, was isolated from antarctic coastal seawater and subjected to a polyphasic taxonomic investigation. cells of the strain were gram-negative, short to elongated rods that were orange-coloured but negative for flexirubin-type pigments, obligately aerobic, chemoheterotrophic and devoid of gliding or flagellar motility. on the basis of 16s rrna gene sequence comparisons, the strain was closely related to members of the genus lewinella (86.3-93.1 %) of the fam ... | 2009 | 19126725 |
| rubidimonas crustatorum gen. nov., sp. nov., a novel member of the family saprospiraceae isolated from a marine crustacean. | a strictly aerobic, gram-negative, reddish-orange pigmented, non-motile and rod-shaped bacterium, designated ak17-053(t) was isolated from a marine crustacean (squillidae) living on tidal flats on the coast of the ariake sea, nagasaki, japan. phylogenetic analysis based on the 16s rrna gene sequence revealed that the novel isolate could be affiliated with the family saprospiraceae of the phylum bacteroidetes and that it showed highest sequence similarity (84%) with lewinella marina mkg-38(t). th ... | 2011 | 21993690 |
