“…The primers 349F and 806R can effectively detected archaeal rDNA (Takai and Horikoshi 2000), and it was widely used in many studies to target archaeal communities by highthroughput 16S rRNA gene pyrosequencing (Cortés-Lorenzo et al 2014;Frank et al 2013;Sato et al 2013;Hao et al 2015;Rago et al 2015). But, among them, one study showed that archaeal sequences comprised only a low proportion (1-49 %) when this primer was used (Sato et al 2013).…”

Purpose Knowledge of archaeal communities is essential for understanding of the mechanism of carbon and nitrogen cycle in the mangrove sediment ecosystem. Presently, little is known about archaeal communities in the Dongzhaigang mangrove sediments. This study aimed to characterize the archaeal communities in sediments of different mangrove stands and to find out the correlations between archaeal communities and the environmental factors of sediments.Materials and methods Sediment samples were collected from the Dongzhaigang mangrove forest for analysis of soil properties and archaeal communities, by national standard methods and Illumina Miseq archaeal 16S ribosomal RNA (rRNA) gene sequencing, respectively. Results and discussion The archaeal community in the Dongzhaigang mangrove forest was constituted by some phyla from BTACK^and BDPANN^supergroups, and dominated by Euryarchaeota. Among sediments of the four mangroves in Dongzhaigang, principal coordinates analysis (PCoA) scatter plot showed a trend of difference in the archaeal community structure in the Bruguiera gymnoihiza and Kandelia candel stands from that in the Laguncularia racemosa and Sonneratia apetala stands. The abundance of the order Methanosarcinales was the highest in the sediments of K. candel mangroves, whereas the order of Methanobacteriales dominated in B. gymnoihiza sediments. The highest richness and diversity values of Archaea occurred in K. candel sediments, while the lowest in B. gymnoihiza. Pearson correlation showed the significant relationships between sediment properties and some dominant genera, with a positive and significant correlation between sediment properties and genus Methanobacterium, coinciding with the maximum values of sediment properties and abundance of Methanobacterium in the sediment of B. gymnoihiza. Such results indicated that the difference of archaeal community structure among mangrove sediments may be caused by the different sediment characteristics. Methanogenic communities in the Dongzhaigang mangrove forest sediments were, at the order level, constituted by Methanobacteriales, Methanomicrobiales, Methanosarcinales, and Methanomassiliicoccales. Conclusions The investigation indicated that the Dongzhaigang mangrove sediment ecosystems support (2016( ) 16:1995( -2004( DOI 10.1007( /s11368-016-1427 diverse archaeal communities and methanogenic communities, and that there was a general trend of difference in the archaeal community structure in the B. gymnoihiza and K. candel mangrove sediments from that in the L. racemosa and S. apetala sediments. Such difference may be caused by the difference in sediment characteristics.

“…It was proven that the significant differences in the community structure depended on the influent salt concentration of a submerged fixed-bed bioreactor. Proteobacteria was found to be the dominant genera in all of the experiments, with ␣-Proteobacteria representing the main order at low salinity and ␥-Proteobacteria representing the dominant order at high salinity (Cortes-Lorenzo et al, 2014). Some sulfate-reducing bacteria (SRB) were found in LYG (Table 4), which are important for the sulfur cycle in a marine sediment and can survive in high saline environments (Moreau et al, 2010).…”

“…Among the three reactors, the relative abundance of Bacteroides in MABR #1 was the largest (23.47%) and they played a key role in the degradation of toxic substances and macromolecules. 55 From the data in Fig. 10(b), at the class level, the main dominant ora in activated sludge (HLWN) were Betaproteobacteria (31.16%), Sphingobacteriia (18.47%) and Alphaproteobacteria (10.95%).…”
