Therefore, microbiologists are facing an arduous choice, either using the universal marker, knowing that these affiliations could be inaccurate, or engaging in more laborious and costly approaches. The rpoD gene, like the 16S rRNA gene, is included in most MLSA procedures and has already been suggested for the rapid identification of certain groups of Pseudomonas. However, a comprehensive overview of the rpoD-based phylogenetic relationships within the Pseudomonas genus is lacking. In this study, we present the rpoD-based phylogeny of 217 type strains of Pseudomonas and defined a cutoff value of 98% nucleotide identity to differentiate strains at the species level. -

Type strains of Pseudomonas are well-known to represent only a small fraction of this diversity and the number of available Pseudomonas genome sequences is increasing rapidly. Consequently, new Pseudomonas species are regularly reported and the number of species within the genus is in constant evolution. -

Fairbanks, Alaska h r A Q t ■ ^% 0 /v AlA s ((0 August 2007 ^>c0^b Abstract Seafood quality can be assessed by determining the bacterial load and flora composition, although classical taxonomic methods are time-consuming and subjective to interpretation bias. A two-prong approach was used to assess a commercially available microbial identification system: confirmation of known cultures and fish spoilage experiments to isolate unknowns for identification. Bacterial isolates from the Fishery Industrial Technology Center Culture Collection (FITCCC) and the American Type Culture Collection (ATCC) were used to test the identification ability of the Sherlock Microbial Identification System (MIS). Twelve ATCC and 21 FITCCC strains were identified to species with the exception of Pseudomonas fluorescens and P. putida which could not be distinguished by cellular fatty acid analysis. The bacterial flora changes that occurred in iced Alaska pink salmon ( Oncorhynchus gorbuscha) were determined by the rapid method. -

Characterisation of Pseudomonas Spp. Isolated from Foods

However subsequent molecular tests did not always confirm the results obtained, thus highlighting the limits of API 20NE. Instead RFLP ITS1 and the sequencing of 16S rRNA gene grouped the isolates into 6 clusters: Pseudomonas fluorescens (cluster I), Pseudomonas fragi (cluster II and V) Pseudomonas migulae (cluster III), Pseudomonas aeruginosa (cluster IV) and Pseudomonas chicorii (cluster VI). The pectinolytic activity was typical of species isolated from vegetable products, especially Pseudomonas fluorescens. Instead Pseudomonas fragi, predominantly isolated from meat was characterised by proteolytic and lipolytic activities. Key words: Pseudomonas fluorescens, enzymatic activity, ITS1. INTRODUCTION the most frequently found species, however the species dis- tribution within the food ecosystem remains relatively The genus Pseudomonas is the most heterogeneous and unknown (Arnaut-Rollier et al., 1999). The principal micro- ecologically significant group of known bacteria, and bial population of many vegetables in the field consists of includes Gram-negative motile aerobic rods that are wide- species of the genus Pseudomonas, especially the fluores- spread throughout nature and characterised by elevated cent forms. -

(a) Species discriminating fecal microbiota of the Soil and Control mice. Mean importance of species identified by random forest are shown in the 5th column. Random forests assigns an importance score to each species by estimating the increase in error caused by removing that species from the set of predictors. In our analysis, we considered a species to be “highly predictive” if its importance score was at least 0.001. T-test was performed for the relative abundances of each species between the two groups of mice. P-values were at least 0.05 to be considered statistically significant.

Ledeganckstraat 35, B-9000 Ghent, Belgium DNA-rRNA hybridizations, DNA-DNA hybridizations, polyacrylamide gel electrophoresis of whole-cell proteins, and a numerical analysis of carbon assimilation tests were carried out to determine the relationships among the phylogenetically misnamed phytopathogenic taxa Pseudomonas avenue, Pseudomonas rubrilineans, “Pseudomonas setariae, ” Pseudomonas cattleyae, Pseudomonas pseudoalcaligenes subsp. citrulli, and Pseudo- monas pseudoalcaligenes subsp. konjaci. These organisms are all members of the family Comamonadaceae, within which they constitute a separate rRNA branch. Only P. pseudoalcaligenes subsp. konjaci is situated on the lower part of this rRNA branch; all of the other taxa cluster very closely around the type strain of P. avenue. When they are compared phenotypically, all of the members of this rRNA branch can be differentiated from each other, and they are, as a group, most closely related to the genus Acidovorax. DNA-DNA hybridization experiments showed that these organisms constitute two genotypic groups. We propose that the generically misnamed phytopathogenic Pseudomonas species should be transferred to the genus Acidovorax as Acidovorax avenue and Acidovorax konjaci. Within Acidovorax avenue we distinguished the following three subspecies: Acidovorax avenue subsp. -

Reddy4, Marcel Huntemann4, Neha Varghese4, Natalia Ivanova4, I- Min Chen4, Markus Göker5, Tanja Woyke4, Hans- Peter Klenk6, Nikos Kyrpides4 and Jorge Lalucat1,3,* Abstract Pseudomonas is the bacterial genus of Gram- negative bacteria with the highest number of recognized species. It is divided phylogenetically into three lineages and at least 11 groups of species. The Pseudomonas putida group of species is one of the most versatile and best studied. It comprises 15 species with validly published names. As a part of the Genomic Encyclopedia of Bacteria and Archaea (GEBA) project, we present the genome sequences of the type strains of five species included in this group: Pseudomonas monteilii (DSM 14164T), Pseudomonas mosselii (DSM 17497T), Pseudomonas plecoglossicida (DSM 15088T), Pseudomonas taiwanensis (DSM 21245T) and Pseudomonas vranovensis (DSM 16006T). These strains represent species of envi- ronmental and also of clinical interest due to their pathogenic properties against humans and animals. Some strains of these species promote plant growth or act as plant pathogens. Their genome sizes are among the largest in the group, ranging from 5.3 to 6.3 Mbp. In addition, the genome sequences of the type strains in the Pseudomonas taxonomy were analysed via genome- wide taxonomic comparisons of ANIb, gANI and GGDC values among 130 Pseudomonas strains classified within the group. -
