Pseudomonas laurentiana sp. nov., an Mn(III)-oxidizing Bacterium Isolated from the St. Lawrence Estuary

Based on the summary of genotypic and phenotypic results, we describe a novel species of the genus Pseudomonas represented by strain GSL-010T and for which the name Pseudomonas laurentiana sp. nov. is proposed

Scholarcy highlights

  • An aerobic, Mn(III)-oxidizing, Gram-negative, motile bacterium was isolated from deep waters of the St Lawrence Estuary and subjected to a polyphasic taxonomic study
  • Isolation was achieved by selecting colonies positive for Mn(III)-citrate oxidation on Minimal Media A agar plates containing 100 μM Mn(III)-citrate at 30oC, pH 7.5 for 5-7 days in the dark
  • P. plecoglossicida NBRC 103162T and P. japonica IAM 15071T were obtained from NITE Biological Resource Center
  • Published genome sequences representing a G+C range of 43-72 mol% were used as standards and G+C values were calculated as per the method of Mesbah et al. The genomic DNA G+C content determined for strain GSL-010T was 59.7%, which was lower than the values reported for P. plecoglossicida and P. japonica
  • Based on the summary of genotypic and phenotypic results, we describe a novel species of the genus Pseudomonas represented by strain GSL-010T and for which the name Pseudomonas laurentiana sp. nov. is proposed
  • The DNA–DNA hybridization values between strain GSL-010T were: P. plecoglossicida; and P. japonica
  • The genomic DNA G+C content of the type strain is 59.7%
