A chemoorganotrophic, moderately halophilic bacterium (strain SMB35) has been isolated from a naphthalene-utilizing microbial community obtained from salt mines (Perm region of Russia). Strain SMB35 grows in a wide salinity range, 0.5 to 30% (wt/vol) NaCl. Cells are gram-negative rods motile by means of a single polar flagellum. The predominant fatty acids(More)
By using fosmidomycin and mevinolin (inhibitors of the synthesis of isoprenoid pigments), spectrophotometry, and mass spectrometry, the presence of isoprenoid pigments is shown in 71 of the 78 strains under study. All of these strains belong to 11 genera of the family Microbacteriaceae. Yellow, orange, and red pigments are found to have absorption spectra(More)
The cell wall of Streptomyces coelicolor M145, a prototrophic plasmidless (SCP1(-) SCP2(-)) variant of strain S. coelicolor A3(2) contains the main glycopolymer represented by Kdn-containing teichulosonic acid with unusual structure which has not been described so far: [structure: see text]. The minor polymer was found to be a poly(diglycosyl 1-phosphate)(More)
This work deals with the taxonomic study of orange-pigmented bacteria isolated from permafrost sediments, rice plots, and soils contaminated with wastes from the chemical and salt industries that were assigned to the genus Brevibacterium on the basis of phenotypic characteristics, as well as of some strains described previously as Brevibacterium linens. The(More)
The cell wall of Actinoplanes lobatus VKM Ac-676(T) (family Micromonosporaceae; order Actinomycetales; class Actinobacteria) contains two anionic glycopolymers. The major one is a teichuronic acid with a linear structure of the chain and heterogeneous repeating units, consisting of glucopyranose residues and statistically alternating residues of(More)
The subject of the present review is the structural diversity and abundance of cell wall teichuronic and teichulosonic acids of representatives of the order Actinomycetales. Recently found teichulosonic acids are a new class of natural glycopolymers with ald-2-ulosonic acid residues: Kdn (3-deoxy-D-glycero-D-galacto-non-2-ulosonic acid) or di-N-acyl(More)
A halotolerant bacterium, strain SMB34T, was isolated from a naphthalene-utilizing bacterial consortium obtained from primitive technogeneous soil (Verkhnekamsk salt deposit, Perm region, Russia) by enrichment procedure. The strain itself was unable to degrade naphthalene and grew at NaCl concentrations up to 11% (w/v). The 16S rRNA-based phylogenetic(More)
The cell wall of Streptomyces sp. VKM Ac-2534, the causative agent of common scab in potato tubers, which does not synthesize thaxtomin and is phylogenetically close to phytopathogen Streptomyces setonii sp. ATCC 25497, contains two anionic carbohydrate-containing polymers. The major polymer is teichuronic acid, whose repeating unit is disaccharide →(More)
The cell walls of Microbispora mesophila strain Ac-1953T (the family Streptosporangiaceae) and Thermobifida fusca Ac-1952T (the family Nocardiopsaceae) were found to contain teichoic acids of a poly(glycerol phosphate) nature. The teichoic acid of M. mesophila (formerly Thermomonospora mesophila) represents a 1,3-poly(glycerol phosphate) containing 5% of(More)
The bacterium formerly known asArthrobacter globiformis 193 has high 1(2)-dehydrogenase activity toward pharmaceutically important steroids, 9(11)-dehydrocortexolone in particular. The complex analysis of the morphostructural, physiological, biochemical, and phylogenetic properties of this bacterium allowed us to reclassify it into Nocardioides simplex (N.(More)
