Proposal of the genus Sphingomonas sensu stricto and three new genera, Sphingobium, Novosphingobium and Sphingopyxis, on the basis of phylogenetic and chemotaxonomic analyses.
Phylogenetic analyses of 16S rRNA gene sequences by distance matrix and parsimony methods indicated that the currently known species of the genus Sphingomonas can be divided into four clusters. Some…
Sphingosinicella microcystinivorans gen. nov., sp. nov., a microcystin-degrading bacterium.
TLDR
Three strains of bacteria that degrade the cyanobacterial hepatotoxin microcystin, Y2T, MDB2 and MDB3, were isolated from a eutrophic lake, Lake Suwa, and the Tenryu River, Japan, and characterized, and it is proposed that they represent a new genus and species of the family Sphingomonadaceae.
Taxonomic study of bacteria isolated from plants: proposal of Sphingomonas rosa sp. nov., Sphingomonas pruni sp. nov., Sphingomonas asaccharolytica sp. nov., and Sphingomonas mali sp. nov.
TLDR
Four new species of the genus Sphingomonas are proposed on the basis of morphological, physiological, and chemotaxonomic characteristics, together with DNA-DNA hybridization and 16S ribosomal DNA sequence comparison data.
Cellular polyamine catalogues of the five classes of the phylum Proteobacteria: distributions of homospermidine within the class Alphaproteobacteria, hydroxyputrescine within the class…
TLDR
Spermidine was the major polyamine in the classes Deltaproteobacteria and Epsilonproteobacteria, suggesting that the occurrence of spermine correlate to their thermophily, as a chemotaxonomic marker.
Parasphingopyxis lamellibrachiae gen. nov., sp. nov., isolated from a marine annelid worm.
TLDR
The novel strain isolated from the trophosome of a tubeworm in Kagoshima Bay, Japan, represents a novel species of a new genus in the family Sphingomonadaceae, for which the name Parasphingopyxis lamellibrachiae gen. nov., sp.
A high-mobility-group protein and its cDNAs from Drosophila melanogaster.
TLDR
A high-mobility-group (HMG) protein and its cDNAs from Drosophila melanogaster are identified, purified, and characterized; HMG D appears to be the major HMG protein of D. melanogasters.
Polyamine Profiles as Chemotaxonomic Marker within Alpha, Beta, Gamma, Delta, and Epsilon Subclasses of Class Proteobacteria : Distribution of 2-Hydroxyputrescine and Homospermidine
Identification, cloning and expression of SodC from an alkaline phosphatase gene fusion library of Mycobacterium avium subspecies Paratuberculosis
TLDR
Polyamine profiles serve as a phenotypic chemotaxonomic marker for the reclassification of the genera belonging to the Flavobacterium-Flexibacter-Cytophaga complex.
Occurrence of homospermidine as a major polyamine in the authentic genus Flavobacterium
TLDR
Polyamines in various Flavobacterium strains and related eubacteria were analyzed and the major polyamine was homospermidine in all 12 strains of the eight authentic species of the genus Flavobacteria studied and in another seven Flavob bacteria species that are taxonomically different from Flavob bacterium and belong to other genera.
Polyamine distribution profiles in newly validated genera and species within the Flavobacterium-Flexibacter-Cytophaga-Sphingobacterium complex.
TLDR
Polyamine profiles serve, as a phenotypic chemotaxonomic marker, for the classification of this complex of strains, and homospermidine was found in all species of Flavobacterium and Pedobacter species of the family Sphingobacteriaceae.
