| thermicanus aegyptius gen. nov., sp. nov., isolated from oxic soil, a fermentative microaerophile that grows commensally with the thermophilic acetogen moorella thermoacetica. | a thermophilic, fermentative microaerophile (et-5b) and a thermophilic acetogen (et-5a) were coisolated from oxic soil obtained from egypt. the 16s rrna gene sequence of et-5a was 99.8% similar to that of the classic acetogen moorella thermoacetica. further analyses confirmed that et-5a was a new strain of m. thermoacetica. for et-5b, the nearest 16s rrna gene sequence similarity value to known genera was approximately 88%. et-5b was found to be a motile rod with a genomic g+c content of 50.3 mo ... | 1999 | 10543831 |
| polyamine analysis for chemotaxonomy of thermophilic eubacteria: polyamine distribution profiles within the orders aquificales, thermotogales, thermodesulfobacteriales, thermales, thermoanaerobacteriales, clostridiales and bacillales. | cellular polyamines of 45 thermophilic and 8 related mesophilic eubacteria were investigated by hplc and gc analyses for the thermophilic and chemotaxonomic significance of polyamine distribution profiles. spermidine and a quaternary branched penta-amine, n4-bis(aminopropyl)norspermidine, were the major polyamine in thermocrinis, hydrogenobacter, hydrogenobaculum, aquifex, persephonella, sulfurihydrogenibium, hydrogenothermus, balnearium and thermovibrio, located in the order aquificales. thermo ... | 2004 | 15747232 |
