“…The resulting maximum-likelihood tree (Figure 5A ) showed a great concordance with α-proteobacterial trees based on complete 16S rRNA genes [ 22 ] or sets of protein families [ 23 ]. Our analysis placed A. caulinodans closest to X. autotrophicus , Nitrobacter winogradskyi , Rhodopseudomonas palustris , and Bradyrhizobium japonicum , consistent with previous taxonomic studies [ 9 , 10 , 13 ]. With A. caulinodans as a reference genome, a graphical representation of the BLAST hits of the proteins encoded by the genomes of the 13 closest relatives was generated with the BLASTatlas tool (Figure 1 ) [ 16 , 17 ].…”

Background: Biological nitrogen fixation is a prokaryotic process that plays an essential role in the global nitrogen cycle. Azorhizobium caulinodans ORS571 has the dual capacity to fix nitrogen both as free-living organism and in a symbiotic interaction with Sesbania rostrata. The host is a fastgrowing, submergence-tolerant tropical legume on which A. caulinodans can efficiently induce nodule formation on the root system and on adventitious rootlets located on the stem.

“…Xanthobacter sp. are diazotrophic bacteria found in diverse soil habitats and in association with rice ( Oryza sativa ) roots [ 12 , 13 ]. Comparison of 16S rRNA sequences indicated that X. flavus and A. caulinodans are strongly related [ 14 ].…”

“…In citrate-amended N-deficient cultures, the increase in Rhizobiales occurred predominantly in the family Hyphomicrobiaceae which are known to contain citrate and hydrocarbon-degraders, and N 2 -fixing species (Wiegel, 2006;Nagamani et al, 2009). We can therefore speculate that Rhizobiales might be performing an important role in N 2 -fixing activity in citrate-amended N-deficient cultures.…”

“…Strains of Xanthobacter autotrophicus have been isolated from a submerged fixed-film reactor with denitrifying capacity and they reduce nitrate or nitrite to nitrous oxide or dinitrogen (Gómez et al, 2005). Some species of Xanthobacter fix nitrogen and some produce extracellular polymeric substances under harsh conditions (Wiegel, 2006).…”

Microorganisms in aerobic granules formed in sequencing batch reactors (SBR) remove contaminants, such as xenobiotics or dyes, from wastewater. The granules, however, are not stable over time, decreasing the removal of the pollutant. A better understanding of the granule formation and the dynamics of the microorganisms involved will help to optimize the removal of contaminants from wastewater in a SBR. Sequencing the 16S rRNA gene and internal transcribed spacer PCR amplicons revealed that during the acclimation phase the relative abundance of Acinetobacter reached 70.8%. At the start of the granulation phase the relative abundance of Agrobacterium reached 35.9% and that of Dipodascus 89.7% during the mature granule phase. Fluffy granules were detected on day 43. The granules with filamentous overgrowth were not stable and they lysed on day 46 resulting in biomass wash-out. It was found that the reactor operation strategy resulted in stable aerobic granules for 46 days. As the reactor operations remained the same from the mature granule phase to the end of the experiment, the disintegration of the granules after day 46 was due to changes in the microbial community structure and not by the reactor operation.
