putrefaciens was identified as a species of Achromobacter, a group comprising various Gram-negative, nonfermentative, oxidase-positive, and rod-shaped bacteria. The species was transferred to the genus Pseudomonas by Long and Hammer in 1941 and placed in Pseudomonas group III/IV of the Shewan ...
Shewanella 屬於γ- proteobacteria革蘭氏陰性桿狀,具運動性,catalase與oxidase陽性,不會產生芽孢的兼性厭氧菌,這類菌叢源屬於腐生型棲水維生的一種伺機性病原.近年來臨床上於熱帶,亞熱帶甚至寒帶國家常有感染病例發生且人類及動物體感染病例數有陸續增多的趨勢,食物汙染事件也層出不窮,據統計大多的感染病例都顯示與...
Shewanella is oxidase positive and is the only nonfermenter that produces hydrogen sulfide on triple sugar iron agar, a key feature that allows easy identification in the laboratory. S. algae can be distinguished from S. putrefaciens by growth at 42° C, growth in 6.5% NaCl, mucoid ...
algae strain BRY was found to reduce Au3+ to Au using hydrogen as the electron donor (Kashefi et al. 2001). Alternatively, Shewanella species have been considered for the bioremediation of different kinds of metals ions or for use in microbial fuel cells (Chen et al. 2015; Liu and Logan ...
Shewanellaceae, a family within the order Alteromonadales, consist of a sole genus Shewanella. Almost all species of this genus are Gram-negative, motile rod with positive oxidase and catalase reaction. Facultatively anaerobic. Oxygen is used as the...
Chantal Iobbi-Nivol2, Vincent Méjean2 & Valérie Michotey1 To explain anaerobic nitrite/nitrate production at the expense of ammonium mediated by manganese oxide (Mn(IV)) in sediment, nitrate and manganese respirations were investigated in a strain (Shewanella algae C6G3) presenting these...
Positive for oxidase and catalase activity. The strains exhibit a minor halo- philicity and thrive when exposed to 1–5% NaCl; they are incapable of growth in the absence of NaCl. Strains are positive for acid production from cellobi- ose, D-glucose, maltose, and sucrose; negative for D-...
processes. The genome ofS.oneidensisMR-1 encodes three terminal oxidases: a bd-type quinol oxidase plus two haem-copper oxidases, a cytochrome c oxidase (genes SO4606–SO4609) and a cbb3-type oxidase (genes SO2361–SO2364)50,51.
Oxidase and catalase positive . Chemoheterotrophic. Facultatively anaerobic. Oxygen is used as the electron acceptor during aerobic growth. Anaerobic growth is predominantly respiratory ; the oxidation of organic carbon compounds or H 2 is coupled to the reduction of various inorganic and organic ...
Shewanella algae is an emerging bacteria rarely implicated as a human pathogen. It was infrequently recovered from clinical specimens probably because of inadequate processing of non-fermenting oxidase-positive gram-negative bacilli. We report here isolation of S. algae in pure culture and mixed with ...
