In this study, total soil microbial DNA and RNA were directly extracted from paddy soils of N0 (control treatment, no nitrogen fertilizer), NPK (balanced fertilization), NPK+LS (balanced fertilization with additional 3.0 t\u00b7hm-2 rice straw incorporation) and NPK+HS (balanced fertilization with additional 6.0 t\u00b7hm-2 rice straw incorporation) treatments in a long-term fertilization experiment of double rice cropping system in Changsha County, Hunan Province. Soil bacteria community structures were evaluated by analyzing the 16S rRNA gene fragments at DNA and cDNA levels with Terminal Restriction Fragment Length Polymorphism (T-RFLP) and quantitative PCR techniques. Balancing fertilization with chemical fertilizers and rice straw incorporation significantly changed the composition of bulk (DNA-based) and potentially active (mRNA-based) soil bacterial community as shown in T-RFLP profiles, and also reduced the bulk soil microbial diversity, but not the potentially active ones, as compared with the control treatment. The DNA-based abundance of 16S rRNA gene was on average 377 times as many as the m-RNA based population size. Compared to N0,balanced fertilization with rice straw incorporation (NPK+LS and NPK+HS) increased the bulk and active copy numbers of 16S rRNA gene, but not for balanced fertilization (NPK). The abundance and microbial community structure were not significantly different between the NPK+LS and NPK+HS treatments. Redundancy analysis (RDA) showed that soil ammonium was the key environmental factor determining the bulk and active soil microbial community structure among the treatments. In conclusion, the effect of fertilization on soil microbial abundance and community structure could be indicated at both DNA and cDNA levels; the cDNA information could better reflect the adaptability of bacterial community to the environmental stress.", "keywords": ["DNA", " Complementary", "Bacteria", "RNA", " Ribosomal", " 16S", "Agriculture", "Oryza", "Fertilizers", "01 natural sciences", "Soil Microbiology", "0105 earth and related environmental sciences"]}, "links": [{"href": "https://doi.org/10.13227/j.hjkx.201604220"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/Huan%20jing%20ke%20xue%3D%20Huanjing%20kexue", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "10.13227/j.hjkx.201604220", "name": "item", "description": "10.13227/j.hjkx.201604220", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.13227/j.hjkx.201604220"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2016-11-01T00:00:00Z"}}, {"id": "10.1890/10-0426.1", "type": "Feature", "geometry": null, "properties": {"updated": "2026-08-23T16:18:21Z", "type": "Journal Article", "created": "2010-12-17", "title": "Consistent Effects Of Nitrogen Fertilization On Soil Bacterial Communities In Contrasting Systems", "description": "<p>Ecosystems worldwide are receiving increasing amounts of reactive nitrogen (N) through anthropogenic activities.

Bacterial community structure was highly responsive to N additions. We observed predictable and consistent changes in the structure of the bacterial communities across both ecosystem types. Our results suggest that bacterial communities across these gradients are more structured by N and/or soil carbon availability than by shifts in the plant community or soil pH associated with the elevated nitrogen inputs.

At high feed intake levels, the proportion of energy lost as CH(4) decreases as the digestibility of the diet increases. Therefore, improving forage digestibility may improve productivity as DM and energy intake are increased. A zero-grazing experiment was conducted to determine the effect of sward DM digestibility (DMD) on DMI, CH(4) emissions, and indices of rumen fermentation of beef animals. Twelve Charolais-cross heifers were assigned to 1 of 2 treatments, with 6 heifers per dietary treatment. Additionally, 4 cannulated Aberdeen Angus-cross steers were randomly allocated to each of these 2 treatments in a crossover design. Dietary treatments consisted of swards managed to produce (i) high digestibility pasture (high DMD) or (ii) pasture with less digestibility (low DMD), both offered for ad libitum intake. All animals were zero-grazed and offered freshly cut herbage twice daily. In vitro DMD values for the high and low DMD swards were 816 and 706 g/kg of DM. Heifers offered the high DMD grass had greater (P < 0.001) daily DMI of 7.66 kg compared with 5.38 kg for those offered the low DMD grass. Heifers offered the high DMD grass had greater (P = 0.003) daily CH(4) production (193 g of CH(4)/d) than those offered the low DMD grass (138 g of CH(4)/d). However, when corrected for DMI, digestible DMI, or ingested gross energy, there was no difference (P > 0.05) in CH(4) production between dietary treatments. For cannulated steers, intake tended (P = 0.06) to be greater for the high DMD grass (5.56 vs. 4.27 kg of DM/d), but rumen protozoa (4.95 x 10(4)/mL; P = 0.62); rumen ammonia (34 mg of N/L; P = 0.24); rumen total VFA (103 mM; P = 0.58), and rumen pH (6.8; P = 0.43) did not differ between treatments. There was no difference in total bacteria numbers, relative expression of the mcrA gene, and numbers of cycles to threshold for fungi when determined using quantitative PCR between dietary treatments with mean values of 73.0 ng/microL, 0.958, and 21.75 C(T), respectively.

In the future, biogas plants must be enabled to use a much broader range of input materials in a flexible and demand-oriented manner. Hence, the microbial communities will be exposed to frequently varying process conditions, while an overall stable process must be ensured. To accompany this transition, there is the need to better understand how biogas microbiomes respond to management measures and how these responses affect the process efficiency. Therefore, 67 microbiomes originating from 49 agricultural, full-scale biogas plants were taxonomically investigated by 16S rRNA gene amplicon sequencing. These microbiomes were separated into three distinct clusters and one group of outliers, which are characterized by a specific distribution of 253 indicative taxa and their relative abundances. These indicative taxa seem to be adapted to specific process conditions which result from a different biogas plant operation. Based on these results, it seems to be possible to deduce/assess the general process condition of a biogas digester based solely on the microbiome structure, in particular on the distribution of specific indicative taxa, and without knowing the corresponding operational and chemical process parameters. Perspectively, this could allow the development of detection systems and advanced process models considering the microbial diversity.</p></article>", "keywords": ["580", "anaerobic digestion", "0301 basic medicine", "2.

We found that diversity indices of bacterial 16S rDNA increased with grazing intensity, suggesting that disturbance led to higher bacterial diversity. The bacterial community structure, measured as species composition, was also affected by grazing. In addition, the change in soil bacterial community composition was maximum under heavy grazing, based on the Sorensen similarity index.

This work aims to provide a holistic view on microbiome assembly and functional diversity in the model site SIN Brescia-Caffaro (Italy), characterized by historical and uneven contamination by organic and inorganic compounds. Here, physical and chemical analyses and microbiota characterization were applied on one-hundred-twenty-seven soil samples to unravel the environmental factors driving bacterial community assembly and biodegradation potential in three former agricultural fields. Chemical analyses showed a patchy distribution of metals, metalloids and polychlorinated biphenyls (PCB) and allowed soil categorization according to depth and area of collections. Likewise, the bacterial community structure, described by molecular fingerprinting and 16S rRNA gene analyses, was significantly different according to collection site and depth. Pollutant concentrations (i.e., hexachloro-biphenyls, arsenic and mercury), nitrogen content and parameters related to soil texture were identified as main drivers of microbiota assembly, being significantly correlated to bacterial community composition. Moreover, bacteria putatively involved in the aerobic degradation of PCBs were enriched over the total bacterial community in topsoils, where the highest activity was recorded using fluorescein hydrolysis as proxy. Metataxonomic analyses revealed the presence of bacteria having metabolic pathways related to PCB degradation and tolerance to heavy metals and metalloids in the topsoil samples collected in all areas. Overall, the provided dissection of soil microbiota structure and its degradation potential in the SIN Brescia-Caffaro can contribute to target specific areas for rhizoremediation implementation.

WAY2 (WAY2) consists of a circular chromosome, three linear replicons and a small circular plasmid. The linear replicons contain typical actinobacterial invertron-type telomeres with the central CGTXCGC motif.

The genome of WAY2 contains five distinct clusters of bph, etb and nah genes, putatively involved in the degradation of several aromatic compounds. These clusters are distributed throughout the linear plasmids. The high sequence homology of the ring-hydroxylating subunits of these systems with other known enzymes has allowed us to model the range of aromatic substrates they could degrade. Further functional characterization revealed that WAY2 was able to grow with biphenyl, naphthalene and xylene as sole carbon and energy sources, and could oxidize multiple aromatic compounds, including ethylbenzene, phenanthrene, dibenzofuran and toluene. In addition, WAY2 was able to co-metabolize 23 polychlorinated biphenyl congeners, consistent with the five different ring-hydroxylating systems encoded by its genome. WAY2 could also use n-alkanes of various chain-lengths as a sole carbon source, probably due to the presence of alkB and ladA gene copies, which are only found in its chromosome.

SPMX co-culture notably promoted root development and plant biomass. Co-cultured SPMX increased root colonization and formed multispecies biofilms, structurally different from those formed by monocultures. By combining 16S rRNA gene amplicon sequencing and fluorescence in situ hybridization with confocal laser scanning microscopy, we found that the composition and spatial organization of the four-species biofilm significantly changed over time. Monoculture P. amylolyticus colonized plant roots poorly, but its population and root colonization were highly enhanced when residing in the four-species biofilm. Exclusion of P. amylolyticus from the community reduced overall biofilm production and root colonization of the three species, resulting in the loss of the plant growth-promoting effects. Combined with spatial analysis, this led to identification of P. amylolyticus as a keystone species.

For bacterial isolates, we compared our nanopore-based approach to matrix-assisted laser desorption ionization-time of flight mass spectrometry-based identification. For species-level profiling of complex bacterial communities, we compared our nanopore-based approach to Illumina shotgun sequencing. For reproducibility purposes, we wrapped the code used to process the sequencing data into a ready-to-use and self-contained Nextflow pipeline.</p>", "keywords": ["DNA", " Bacterial", "1303 Biochemistry", "gut microbiome", "610 Medicine & health", "Microbiology", "Workflow", "1311 Genetics", "RNA", " Ribosomal", " 16S", "1312 Molecular Biology", "1706 Computer Science Applications", "DNA Barcoding", " Taxonomic", "Humans", "DNA sequencing", "Bacteria", "10179 Institute of Medical Microbiology", "Microbiota", "2404 Microbiology", "1314 Physiology", "bioinformatics", "QR1-502", "Nanopore Sequencing", "1105 Ecology", " Evolution", " Behavior and Systematics", "Spectrometry", " Mass", " Matrix-Assisted Laser Desorption-Ionization", "570 Life sciences; biology", "2611 Modeling and Simulation", "Research Article"]}, "links": [{"href": "https://doi.org/PMC11494973"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/mSystems", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "PMC11494973", "name": "item", "description": "PMC11494973", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/PMC11494973"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2024-04-11T00:00:00Z"}}, {"id": "PMC8881608", "type": "Feature", "geometry": null, "properties": {"updated": "2026-08-23T16:24:27Z", "type": "Journal Article", "created": "2022-02-25", "title": "Different gut microbial communities correlate with efficacy of albendazole-ivermectin against soil-transmitted helminthiases", "description": "Abstract                   <p>                     Soil-transmitted helminth infections represent a large burden with over a quarter of the world\uffe2\uff80\uff99s population at risk. Low cure rates are observed with standard of care (albendazole); therefore, a more effective combination therapy (albendazole and ivermectin) is being investigated but showed variable treatment efficacies without evidence of intrinsic parasite resistance.
