E carboxylase or phosphoenolpyruvate (PEP) (cf. Hansen and Juni, 1979). Proteins for succinyl-CoA synthetase and for acetate activation by acetate kinase and phosphate acetyltransferase had been identified by proteomics; having said that, identification of acetyl-CoA transferase suggests that r9c1 also used CoA transferase/hydrolase for each acetate activation andThe ISME JournalCommunity proteogenomics of the subsurface KM Handley et alTable 2 Summary data of genomic bins around the final Illumina Velvet olumbus assemblyBin Longest PE-scaffold (kb) PE-scaffold (#) ARCa (s.d.)

Members of this sulfate-reducing genus are incomplete oxidizers and are only identified to use acetate mixotrophically with H2 (Dias et al., 2008). Assuming that r9c8 was also lowering sulfate, or other inorganic compounds respired by Desulfomicrobium species (one example is, thiosulfate and nitrate), then it would probably happen to be substrate restricted, and dependent around the production of H2 or organic acids by other community members. Most Desulfomicrobium species are also capable to ferment select organic acids (Dias et al., 2008). Other acetate oxidizers. Handful of proteins were identified from Desulfuromonadales r9c7, owing partly to incomplete genomes (Table two, Figure 4b). Proteins and genes identified could be attributed to either the Geobacteror Desulfuromonas-like bacteriaThe ISME Journalcomprising the r9c7 bin. Some genes, but no proteins, have been detected for nitrogen fixation, ATP.
