Fungi are key players in vital ecosystem services, spanning carbon cycling, decomposition, symbiotic associations with cultivated and wild plants pathogenicity. The high importance of fungi processes contrasts the incompleteness our understanding patterns fungal biogeography environmental factors that drive those patterns. To reduce this gap knowledge, we collected validated data published on composition soil communities terrestrial environments including plant-associated habitats made them...

Arbuscular mycorrhizal (AM) fungi are crucial mutualistic symbionts of the majority plant species, with essential roles in nutrient uptake and stress mitigation. The importance AM ecosystems contrasts our limited understanding patterns fungal biogeography environmental factors that drive those patterns. This article presents a release newly developed global dataset (GlobalAMFungi database, https://globalamfungi.com) aims to reduce this knowledge gap. It contains almost 50 million...

Abstract Plants interact with diverse microorganisms that play a crucial role in plant growth and development. The diversity distribution of microbiota are altered by anthropogenic environmental change, leading to subsequent impacts on ecosystems. Modeling the plant‐associated microbes is critical for predicting managing future changes microbial function, but challenges open questions when developing these models still remain. We present conceptual framework process‐oriented predictive...

Soil microbial communities are continuously exposed to H2 diffusing into the soil from atmosphere. N2-fixing nodules represent a peculiar microniche in where can reach concentrations up 20,000 fold higher than global atmosphere (0.530 ppmv). In this study, we investigated impact of exposure on bacterial community structure using dynamic microcosm chambers simulating and nodules. Biphasic kinetic parameters governing oxidation activity changed drastically upon elevated exposure, corresponding...

ABSTRACT The enrichment of H 2 -oxidizing bacteria (HOB) by generated nitrogen-fixing nodules has been shown to have a fertilization effect on several different crops. benefit HOB is attributed their production plant growth-promoting factors, yet interactions with other members soil microbial communities received little attention. Here we report that the energy potential , when supplied soil, alters ecological niche partitioning and fungi, multifaceted consequences for both generalist...

Stable and efficient performance of biological treatment plants requires optimization system operating parameters. Among the various parameters, temperature is an important factor that influences microbial community, which responsible for removal organic pollutants. This study investigated effect on microbiome a submerged membrane bioreactor (SMBR) treating hospital wastewater (HWW). Specifically, temperatures (T=20°C, 15°C, 10°C) pharmaceuticals from HWW was examined. The maximum chemical...

Trace gas uptake by microorganisms controls the oxidative capacity of troposphere, but little is known about how this important function affected changes in soil microbial diversity. This article bridges that knowledge gap examining response community-level physiological profiles (CLPPs), carbon dioxide (CO 2 ) production, and molecular hydrogen (H monoxide (CO) oxidation activities to manipulation diversity microcosms. Microbial was manipulated mixing nonsterile sterile with without...

The separation of light and heavy sludge, as well the aggregation rate floccular are two critical aspects rapid granulation process in sequencing batch reactors (SBRs) early stages. In this study, we investigated impact a method to improve both sludge by coupling effluent external conditioning with FeCl3 addition then reintroducing it into SBR. By supplementation 0.1 g Fe3+ (g dried (DS))-1, concentration extracellular polymeric substances (EPS) retention efficiency greatly increased,...

Abstract Background The total bacterial and fungal functional richness was recently predicted to be millions of KEGG level 3 functions but due limited space resource availability together with constraining environmental conditions, the local functionality only comprises a subset functionality. However, widespread whose abundance redundancy depends on species or sequencing depth could bias indices. Here, we used 20 randomly chosen extant metagenomes from low high each aerial, aquatic...
