“…In the present study, we predicted the microbial functions involved in the synthesis of major and trace elements required for bacterial growth. In the river area mainly under forest land, the major functional groups were related to methylotrophy (Tami et al, 2015), methanol oxidation (Pastawan et al, 2020), anoxygenic photoautotrophy S oxidation, anoxygenic photoautotrophy H 2 oxidation, aerobic anoxygenic phototrophy (Sasikala & Ramana, 1995), oxidation, nitrite ammonification (Howie‐Esquivel & Spicer, 2010), nitrate ammonification, nitrification, aerobic nitrite oxidation, anoxygenic photoautotrophy, aerobic NH 3 oxidation, and microelement (Mn and Fe) oxidation. Most of the functions are involved in the synthesis of organic compounds with complex structures to support bacterial growth.…”

Microbiota play essential roles in nitrogen (N) cycling in freshwater river ecosystems. However, our understanding of microbial functional groups associated with N cycling (especially denitrification) in freshwater rivers under anthropogenic disturbance is still poor. Here, we studied the impacts of different land-use types on denitrificationrelated microbiota in the Weihe River, Hanjiang River, and their tributaries, in the Qinling Mountains, China. The major land-use types in the three river areas were divided into natural (forest, shrub, grassland, and open water) and anthropogenic (agricultural and urbanized land) types. A landscape survey of microbiota in the river water and sediment was carried out with extensive sample sources based on deep 16S rRNA gene sequencing, which yielded operational taxonomic units for predicting functional groups. With increases in proportions of agricultural and urbanized land areas, electrical conductivity, total N, ammonium-N, and nitrate-N all increased in water samples. Conversely, microbial diversity exhibited a decreasing trend in water samples, whereas the relative abundance of denitrification-related functional groups increased, with increases in the proportions of agricultural and urbanized land areas.The relative abundances of denitrification-and human-related microbial functional groups in sediment samples were distinctively higher in Weihe River (mainly under agriculture and urbanization), when compared with those of Hanjiang River and Qinling tributaries (dominated by forests). The results indicate that anthropogenic landuse types, such as agricultural and urbanized land, result in simple microbial community structure and stimulate microbe-mediated denitrification in freshwater rivers.agricultural land, denitrification, freshwater ecosystems, land-use type, microbiota, urbanized land | BACKGROUNDFreshwater is a fundamental component of aquatic ecosystems and is important for coupling of biogeochemical cycles in lands, rivers, and oceans (Aufdenkampe et al., 2011).

Microbiota play essential roles in nitrogen (N) cycling in freshwater river ecosystems. However, microbial functional groups associated with N cycling (especially denitrification) in freshwater rivers under anthropogenic disturbance are still poorly understood. Here, we studied the impacts of different land-use types on denitrification-related microbial communities in Weihe River, Hanjiang River, and their tributaries, in the Qinling Mountains, China. The major land-use types in the three river areas were divided into natural (forest, shrub, grassland, and open water) and anthropogenic (agricultural and urbanized land) types.

With increases in proportions of agricultural and urbanized land areas, electrical conductivity, total N, ammonium-N, and nitrate-N all increased in water samples. Conversely, microbial diversity exhibited a decreasing trend in water samples, whereas the relative abundance of denitrification-related functional groups increased, with increases in the proportions of agricultural and urbanized land areas. The relative abundances of denitrification- and human-related microbial functional groups in sediment samples were distinctively higher in Weihe River (mainly under agriculture and urbanization), when compared with those of Hanjiang River and Qinling tributaries (dominated by forests). The results indicate that anthropogenic land-use types, such as agricultural and urbanized land, result in simple microbial community structure and stimulate microbe-mediated denitrification in freshwater rivers.

We present the draft genome sequence of Bradyrhizobium sp. strain Ce-3, which produced exopolysaccharide (EPS) and oxidized methanol in the presence of Ce 3+ . The genome for strain Ce-3 was estimated at 7,608,996 bp and showed that the strain is closely related to Bradyrhizobium erythrophlei MT12 and Bradyrhizobium sp. strain C9.
