Disease relevance of Deltaproteobacteria


High impact information on Deltaproteobacteria

  • We have employed a maximum likelihood and a maximum parsimony approach to detect evidence of positive Darwinian selection in Omp85 homologues from 10 delta-proteobacteria and have identified 14 amino acid sites that show evidence of being under the influence of adaptive evolution [3].
  • An organism represented by an rrnA sequence previously retrieved from Mono Lake and affiliated with the Desulfobulbaceae (Deltaproteobacteria) appears to be an important member of the arsenate-reducing, sulfide-oxidizing community [4].
  • A sixth phylotype belonging to the delta-Proteobacteria (Delta 3 symbiont) was found in only one of the two host populations [5].
  • Alignment of 16S rRNA sequences indicated that strain MLMS-1 was in the delta-Proteobacteria, located near sulfate reducers like Desulfobulbus sp. (88 to 90% similarity) but more closely related (97%) to unidentified sequences amplified previously from Mono Lake. However, strain MLMS-1 does not grow with sulfate as its electron acceptor [6].
  • The isolate, designated strain K1, is a member of the delta proteobacteria and is related to other known sulfur and ferric iron reducers [7].

Chemical compound and disease context of Deltaproteobacteria

  • To test the hypothesis that cells were extracted without phylogenetic bias, the relative abundance (depth distribution) of five major divisions of the gram-negative mesophilic sulfate-reducing delta proteobacteria were determined in sediments maintained in a tidal mesocosm system [8].

Biological context of Deltaproteobacteria


Gene context of Deltaproteobacteria

  • The results suggest that RS-1 is a member of the delta-Proteobacteria, and it appears to represent a new genus [1].
