| [geoalkalibacter ferrihydriticus gen. nov., sp. nov., the first alkaliphilic representative of the family geobacteraceae, isolated from a soda lake]. | investigation of iron reduction in bottom sediments of alkaline soda lakes resulted in the isolation of a new obligately anaerobic iron-reducing bacterium, strain z-0531, from lake khadyn (tuva republic, russia) sediment samples. the cells of strain z-0531 are short (1.0-1.5 by 0.3-0.5 microm), motile, non-spore-forming, gram-negative rods. the isolate is an obligate alkaliphile, developing in the ph range of 7.8-10.0, with an optimum at ph 8.6. it does not require nacl but grows at nacl concent ... | 2006 | 17205802 |
| geoalkalibacter subterraneus sp. nov., an anaerobic fe(iii)- and mn(iv)-reducing bacterium from a petroleum reservoir, and emended descriptions of the family desulfuromonadaceae and the genus geoalkalibacter. | a strictly anaerobic fe(iii)-reducing bacterium, designated strain red1(t), was isolated from the production water of the redwash oilfield, usa. the cells were motile rods (1-5x0.5-0.6 microm) that stained gram-negative and possessed polar flagella. strain red1(t) obtained energy from the reduction of fe(iii), mn(iv), nitrate, elemental sulfur and trimethylamine n-oxide in the presence of a wide range of electron donors, including a variety of organic acids, alcohols, biological extracts and hyd ... | 2009 | 19329606 |
