Pseudomonas lini sp. nov., a novel species from bulk and rhizospheric soils.

Abstract

The taxonomic position of eight fluorescent Pseudomonas strains isolated from bulk and rhizospheric soils, and from water was examined. These eight strains clustered in one phenon together with Pseudomomas mandelii (CFBP 4844T), but could still be differentiated from this type strain by four phenotypic features. The eight stains exhibited internal DNA-DNA hybridization values ranging from 60 to 100%, with deltaTm below 5 degrees C (3.9 and 4.3 degrees C) for the lowest values (60 and 66%). The percentages of hybridization with type or reference strains of other Pseudomonas species tested ranged from 12 to 60% (deltaTm = 5.5 degrees C), indicating that the eight isolates studied constituted a discrete DNA homology group. Comparison of the 16S rDNA sequence of the strain representing this group (CFBP 5737T) with the sequences of other strains belonging to the genus Pseudomonas revealed that strain CFBP 5737T was a member of this genus and that these bacteria did not cluster with any previously described species of the genus Pseudomonas. The eight isolates belonged to two siderovars different from those described so far. On the basis of the results of phenotypic, DNA-DNA and phylogenetic analyses, and of siderotyping, a new species, Pseudomonas lini sp. nov. (type strain CFBP 5737T) is proposed.

Comparative Genetic Diversity of the narG , nosZ , and 16S rRNA Genes in Fluorescent Pseudomonads

“…The abilities of the type strains to dissimilate nitrate and nitrogenous oxide were in agreement with previous reports (6,20,29). P. aeruginosa CFBP 2466 T and P. lini CFBP 5737 T were total denitrifiers, P. chlororaphis CFBP 2132…”

Microbial Successions Are Associated with Changes in Chemical Profiles of a Model Refrigerated Fresh Pork Sausage during an 80-Day Shelf Life Study

“…Although multiple species of Pseudomonas (P. poae, P. azotoformans, P. stutzeri, P. syringae, P. lini, and P. psychrophila) were present at low levels (ϳ0.005 to 0.01%) at time zero, only P. lini and P. psychrophila showed a dramatic increase in abundance during phase I. Strains belonging to each of these species are known to be psychrotrophic, and we would therefore have expected all six of these species to grow at refrigeration temperatures (25)(26)(27)(28)(29), leaving open the question as to why only P. lini and P. psychrophila showed such a dramatic growth in the sausage. It is possible that P. poae, P. azotoformans, and P. stutzeri are selectively inhibited by the antimicrobial characteristics of the spice blend.…”
