Polyphasic taxonomy of the genus Shewanella and description of Shewanella oneidensis sp. nov.
The genus Shewanella has been studied since 1931 with regard to a variety of topics of relevance to both applied and environmental microbiology. Recent years have seen the introduction of a large number of new Shewanella-like isolates, necessitating a coordinated review of the genus. In this work, the phylogenetic relationships among known shewanellae were examined using a battery of morphologi...
متن کاملShewanella psychrophila sp. nov. and Shewanella piezotolerans sp. nov., isolated from west Pacific deep-sea sediment.
Two Shewanella-like bacterial strains, WP2(T) and WP3(T), which were isolated from west Pacific deep-sea sediment, were studied to determine their taxonomic position. Cells of the two bacteria were facultatively anaerobic, Gram-negative rods and motile by means of a single polar flagellum. Strain WP2(T) was psychrophilic, growing optimally at about 10-15 degrees C, whereas strain WP3(T) was psy...
متن کاملReclassification of Shewanella putrefaciens Owen's genomic group II as Shewanella baltica sp. nov.
The taxonomic relationship between several Shewanella putrefaciens isolates from the Baltic Sea and reference strains of this species is presented in this study. Results from DNA-DNA hybridization using a newly developed non-radioactive detection system and from 16S rRNA gene sequencing demonstrated that S. putrefaciens is a heterogeneous species containing more than a single genomic group. The...
متن کاملSpatiometabolic stratification of Shewanella oneidensis biofilms.
Biofilms, or surface-attached microbial communities, are both ubiquitous and resilient in the environment. Although much is known about how biofilms form, develop, and detach, very little is understood about how these events are related to metabolism and its dynamics. It is commonly thought that large subpopulations of cells within biofilms are not actively producing proteins or generating ener...
متن کاملSelenite and tellurite reduction by Shewanella oneidensis.
Shewanella oneidensis MR-1 reduces selenite and tellurite preferentially under anaerobic conditions. The Se(0) and Te(0) deposits are located extracellularly and intracellularly, respectively. This difference in localization and the distinct effect of some inhibitors and electron acceptors on these reduction processes are taken as evidence of two independent pathways.
