“…This high abundance was, however, very surprising in view of the sensitivity of Nitrosopumilus and other ammonia oxidizers to Macondo crude oil (25). Nitrosopumilus was even proposed as a bioindicator to map future spills (25). In contrast, Rivers et al (14) reported that Nitrosopumilus was similarly active in plume and nonplume samples during the DWH spill.…”

“…Full ecosystem recovery is intimately linked to microbial community recovery. Microorganisms might also serve as highly sensitive bioindicators (25), as they have been shown to be sensitive to very low concentrations of pollutants, especially with regard to their transcriptome (26)(27)(28). For these reasons, microorganisms could be used as indicators of pollution and ecosystem recovery through the examination of their gene content and gene expression patterns.…”

c Several studies have assessed the effects of the released oil on microbes, either during or immediately after the Deepwater Horizon accident. However, little is known about the potential longer-term persistent effects on microbial communities and their functions. In this study, one water column station near the wellhead (3.78 km southwest of the wellhead), one water column reference station outside the affected area (37.77 km southeast of the wellhead), and deep-sea sediments near the wellhead (3.66 km southeast of the wellhead) were sampled 1 year after the capping of the well. In order to analyze microbial community composition, function, and activity, we used metagenomics, metatranscriptomics, and mineralization assays. Mineralization of hexadecane was significantly higher at the wellhead station at a depth of ϳ1,200 m than at the reference station. Community composition based on taxonomical or functional data showed that the samples taken at a depth of ϳ1,200 m were significantly more dissimilar between the stations than at other depths (surface, 100 m, 750 m, and >1,500 m). Both Bacteria and Archaea showed reduced activity at depths of ϳ1,200 m when the wellhead station was compared to the reference station, and their activity was significantly higher in surficial sediments than in 10-cm sediments. Surficial sediments also harbored significantly different active genera than did 5-and 10-cm sediments. For the remaining microbial parameters assessed, no significant differences could be observed between the wellhead and reference stations and between surface and 5-to 10-cm-deep sediments.

“…is inhibited by oil (Urakawa et al, 2012), but the diversity of AOA has been shown to have increased in situ up to 1 year following the DWH oil spill (Newell et al, 2013). Analysis of the subsurface plume, however, indicated that there are no major changes in the structure of the archaeal community resulting from the DWH spill (Redmond & Valentine 2012) and it is evident that further studies are required to fully elucidate the impact of oil on archaeal diversity, community structure and function.…”

“…The ammonia oxidizing archaea Nitrososphaera sp. represented 6.1% of total sequences in noncontaminated soils and only 2.8% in petroleum-contaminated soils, a reduction that was attributed by the authors to the higher sensitivity of AOA in comparison to AOB to crude oils hydrocarbons, observed in other studies [119, 120]. …”

In recent years, archaeal diversity surveys have received increasing attention. Brazil is a country known for its natural diversity and variety of biomes, which makes it an interesting sampling site for such studies. However, archaeal communities in natural and impacted Brazilian environments have only recently been investigated. In this review, based on a search on the PubMed database on the last week of April 2016, we present and discuss the results obtained in the 51 studies retrieved, focusing on archaeal communities in water, sediments, and soils of different Brazilian environments. We concluded that, in spite of its vast territory and biomes, the number of publications focusing on archaeal detection and/or characterization in Brazil is still incipient, indicating that these environments still represent a great potential to be explored.
