The genus Caulobacter is composed of prosthecate bacteria often specialized for oligotrophic environments. The taxonomy of Caulobacter has relied primarily upon morphological criteria: a strain that visually appeared to be a member of the Caulobacter has generally been called one without challenge. A polyphasic approach, comprising 16S rDNA sequencing,(More)
The microbial content of printing paper machines, running at a temperature of 45-50 degrees C and at pH 4.5-5, was studied. Bacteria were prevalent colonizers of the machine wet end and the raw materials. A total of 390 strains of aerobic bacteria were isolated and 86% of these were identified to genus and species by biochemical, chemotaxonomic and(More)
A polyphasic taxonomic approach was applied to the study of a Gram-negative bacterium (B2(T)) isolated from soil by selective enrichment with pentachlorophenol. 16S rRNA gene sequence analysis of strain B2(T) showed that the strain belongs to the genus Achromobacter within the Betaproteobacteria. The 16S rRNA gene sequence displayed more than 99 %(More)
Two cauliform bacteria (CM243T and CM251) isolated by J. Poindexter from the Atlantic Ocean were characterized by 16S rRNA gene sequencing, TaqI restriction fragment length polymorphism and single-strand conformation polymorphism analyses of the internally transcribed 16S-23S rDNA spacer (ITS1) region, analysis of fatty acids from cellular lipids, mass(More)
Endospore-forming strains were isolated from corn-compost treated with olive-mill wastewater ('alpechin'). The strains were taxonomically studied and proposed as a novel Paenibacillus species. These organisms (strains B.3T, B.7 and B.9) were particularly distinguishable from other aerobic spore-forming species by their ability to grow optimally in 100%(More)
We compared the 16S rRNA gene sequences of 14 strains of Pseudomonas stutzeri, including type strain CCUG 11256 and strain ZoBell (= ATCC 14405), which represented the seven P. stutzeri genomovars (DNA-DNA similarity groups) that have been described. Our sequence analysis revealed clusters which were highly correlated with genomovar clusters derived from(More)
Seven psychrotolerant, Gram-negative bacterial strains, five dust- and airborne isolates (MA101b(T), MA306a, MA405/90, MA-olki(T) and NW12(T)) and two from the Antarctic (Ant 20 and M3C203B-B), were subjected to a polyphasic characterization to determine their taxonomic position. High 16S rDNA sequences similarities (99.3-100.0 %) demonstrated that they(More)
A polymerase chain reaction-based approach was developed for species identification of Pseudomonas strains and for the direct detection of Pseudomonas populations in their natural environment. A highly selective set of primers (PsEG30F and PsEG790R), giving an amplicon of 760 nucleotides in length, was designed based on the internal conserved sequences of(More)
A combined phylogenetic and multilocus DNA sequence analysis of 26 Pseudomonas stutzeri strains distributed within the 9 genomovars of the species has been performed. Type strains of the two most closely related species (P. balearica, former genomovar 6, and P. mendocina), together with P. aeruginosa, as the type species of the genus, have been included in(More)
In this study we used and evaluated three rapid molecular typing methods for the identification of three frequent, clinically significant Salmonella serovars on the basis of the ease, simplicity and reproducibility of the chosen methods. We determined the genetic diversity among several isolates of Salmonella enteritidis, S. typhimiurium and S. virchow, and(More)
