“…The relative abundance of anaerobic genera such as Clostridium IlI, Sporomusa, and Clostridium XIVa was enriched in the lower taproot or fibrous roots, and these taxa were often prevalent in anaerobic environments with abundant organic materials (Nevin et al, 2011;Edwards et al, 2013;Ðapa et al, 2013). Genera such as Rhizobium, Azotobacter, and Azospirillum were enriched at the lower fibrous roots, which is in agreement with the fact that nitrogen fixation occurs only under anaerobic conditions (Hayat et al, 2010;Meena et al, 2017;Huang et al, 2021). Other genera such as Hydrogenophaga and Magnetospirillum are also known to adapt to anaerobic conditions by nitrate respiration (Golby et al, 2012).…”

The properties of plant rhizosphere are dynamic and heterogeneous, serving as different habitat filters for or against certain microorganisms. Herein, we studied the spatial distribution of bacterial communities in the rhizosphere of pepper plants treated with a disease-suppressive or non-suppressive soil. The bacterial richness was significantly (p < 0.05) higher in plants treated with the disease-suppressive soil than in those treated with the non-suppressive soil. Bacterial richness and evenness greatly differed between root parts, with decrease from the upper taproot to the upper fibrous root, the lower taproot, and the lower fibrous root. As expected, the bacterial community in the rhizosphere differed between suppressive and non-suppressive soil. However, the spatial variation (36%) of the bacterial community in the rhizosphere was much greater than that explained by soils (10%). Taxa such as subgroups of Acidobacteria, Nitrosospira, and Nitrospira were known to be selectively enriched in the upper taproot. In vitro Bacillus antagonists against Phytophthora capsici were also preferentially colonized in the taproot, while the genera such as Clostridium, Rhizobium, Azotobacter, Hydrogenophaga, and Magnetospirillum were enriched in the lower taproot or fibrous root. In conclusion, the spatial distribution of bacterial taxa and antagonists in the rhizosphere of pepper sheds light on our understanding of microbial ecology in the rhizosphere.

“…Species of the genus Vibrio are fairly easy to isolate from marine environments. At the time of writing, the genus Vibrio contains more than 130 species with validly published names (https://lpsn.dsmz.de/genus/vibrio), and many of them have been identified in recent years, including Vibrio algicola [3], Vibrio aquaticus [4], Vibrio ouci [4], Vibrio sinensis [5], Vibrio viridaestus [5], Vibrio taketomensis [6], Vibrio agarilyticus [7], Vibrio nitrifigilis [8], Vibrio ulleungensis [9], Vibrio ziniensis [10], Vibrio paracholerae [11], Vibrio ostreae [12] and Vibrio tarriae [13]. In addition, they can live on the surfaces or in the intestines of marine animals.…”

Two Gram-stain-negative, facultatively anaerobic, motile, rod-shaped and flagellated marine bacteria, designated strains DBSS07T and ZSDZ65T, were isolated from the surface sediments of the Bohai sea and Qingdao coastal seawater, respectively. Phylogenetic analysis based on 16S rRNA genes, multilocus sequence analysis (MLSA), phylogenomic analysis of single-copy gene families and whole-genome data placed DBSS07T and ZSDZ65T within the genus Vibrio . DBSS07T was most closely related to Vibrio aestivus M22T, with 97.51 % sequence similarity, whereas ZSDZ65T was most closely related to Vibrio variabilis R-40492T with 97.58 % sequence similarity. DBSS07T grew with 1–7 % (w/v) NaCl (optimum 3 %), at 16–37 °C (optimum 28 °C) and at pH 6.0–9.0 (optimum pH 7.0); whereas ZSDZ65T grew with 1–5 % (w/v) NaCl (optimum 2 %), at 16–32 °C (optimum 28 °C) and at pH 6.0–9.0 (optimum pH 8.0). Both strains shared the same major fatty acid components (more than 10 % of total fatty acids) of summed feature 3 (C16 : 1ω7c or/and C16 : 1ω6c), with different proportions. The DNA G+C contents of DBSS07T and ZSDZ65T were 44.7 and 44.3 %, respectively. On the basis of the results of polyphasic analysis, DBSS07T and ZSDZ65T are considered to represent novel species within the genus Vibrio , for which the names V. paucivorans sp. nov. (type strain, DBSS07T = KCTC 82896T= MCCC 1K06284T) and V. qingdaonensis sp. nov. (type strain, ZSDZ65T = KCTC 82893T = MCCC 1K06289T) are proposed, respectively.

“…In both field observations and experimental manipulations, we saw higher rates of nitrogen fixation in sediments with higher C:N values, indicating lower quality organic matter (Fulweiler et al., 2007, 2013). Organic matter rich coastal sediments may also support fermentative nitrogen fixing (Gandy & Yoch, 1988; Huang et al., 2021; Streicher & Valentine, 1973). And finally, sediments are often rich in other elements (e.g., methane, reduced iron, sulfide, and hydrogen) that can support chemoautotrophic nitrogen fixation, a process now reported in numerous habitats including marine ecosystems (Desai et al., 2013; Zehr & Capone, 2020).…”

More Foxes than Hedgehogs: The Case for Nitrogen Fixation in Coastal Marine Sediments

Nitrogen fixation is an important process connecting the vast atmospheric pool of di‐nitrogen gas to the biosphere. Nitrogen fixation is an energy intensive process, and it is historically thought to occur only to meet nitrogen demands. However, over the last two decades research has demonstrated that sediment nitrogen fixation occurs in a variety of coastal environments, including those where reduced nitrogen is abundant. This can be met with skepticism when nitrogen fixation is viewed solely as a nitrogen limitation relief mechanism. Here I propose that coastal sediments are actually ideal environments for nitrogen fixation and synthesize ideas on why this is the case. My goal is to help the community embrace a new paradigm for sediment nitrogen fixation and to see it as an important and even expected process. In doing so, I hope to motivate future research on the spatial and temporal rate dynamics of sediment nitrogen fixation as well as on the sediment nitrogen fixation community composition and activity.
