| pantoea rodasii sp. nov., pantoea rwandensis sp. nov. and pantoea wallisii sp. nov., three novel pantoea species isolated from eucalyptus. | several gram-negative, facultatively anaerobic bacterial isolates were obtained from eucalyptus seedlings showing symptoms of bacterial blight and dieback in colombia, rwanda and south africa. partial 16s rrna gene sequencing, together with partial gyrb sequencing, placed the isolates in the genus pantoea and indicated they constituted three novel species. multilocus sequence analysis (mlsa) based on partial sequences of gyrb, rpob, infb and atpd revealed p. dispersa, p. eucrina and p. cypripedi ... | 2011 | 21841003 |
| discovery of pantoea rodasii strain nd03 that produces n-(3-oxo-hexanoyl)-l-homoserine lactone. | proteobacteria use quorum sensing to regulate target gene expression in response to population density. quorum sensing (qs) is achieved via so-called signalling molecules and the best-studied qs signalling system uses n-acyl homoserine lactones (ahls). this study aimed to identify and characterize the production of ahls by a bacterium nd03 isolated from a malaysian tropical rainforest waterfall. molecular identification showed that nd03 is a pantoea sp. closely related to pantoea rodasii. we use ... | 2014 | 24859023 |
| chania multitudinisentens gen. nov., sp. nov., an n-acyl-homoserine-lactone-producing bacterium in the family enterobacteriaceae isolated from landfill site soil. | phylogenetic and taxonomic characterization was performed for bacterium rb-25t, which was isolated from a soil sample collected in a former municipal landfill site in puchong, malaysia. growth occurred at 20-37 °c at ph 5-8 but not in the presence of 9 % (w/v) nacl or higher. the principal fatty acids were c16:0, c18:1ω7c and summed feature 3 (c16:1ω7c and/or iso-c15:0 2-oh). ubiquinone-8 was the only isoprenoid quinone detected. polar lipid analysis revealed the presence of phospholipid, phosph ... | 2016 | 26978486 |
