Chemodiversity of Dissolved Organic Matter Is Governed by Microbial Biogeography in Inland Waters

Environmental Science & Technology, Год журнала: 2023, Номер 57(20), С. 7753 - 7763

Опубликована: Май 10, 2023

Dissolved organic matter (DOM) is crucial for the carbon biogeochemical cycle and has a close link with microbiome in aquatic ecosystems; however, causal relationship between DOM microbial diversity inland waters not very clear so far. Therefore, national survey of China's was conducted, chemical composition community were determined by Fourier transform ion cyclotron resonance mass spectrometry high-throughput sequencing to clarify abovementioned question. Here, we found that chemodiversity governed assembly waters, vice versa. Under control biogeography, showed geographical distribution difference. Water mainly constrained bacterial archaeal composition, whereas sediment controlled eukaryotic fungal composition. In addition, also affected interaction different groups sediments. The study first proposes regulatory mechanism on pattern chemodiversity, thus further deepening understanding cycle.

The role of microbiomes in gastrointestinal cancers: new insights

Frontiers in Oncology, Год журнала: 2024, Номер 13

Опубликована: Фев. 1, 2024

Gastrointestinal (GI) cancers constitute more than 33% of new cancer cases worldwide and pose a considerable burden on public health. There exists growing body evidence that has systematically recorded an upward trajectory in GI malignancies within the last 5 to 10 years, thus presenting formidable menace health human population. The perturbations microbiota may have noteworthy influence advancement cancers; however, precise mechanisms behind this association are still not comprehensively understood. Some bacteria been observed support development, while others seem provide safeguard against it. Recent studies indicated alterations composition abundance microbiomes could be associated with progression various cancers, such as colorectal, gastric, hepatic, esophageal cancers. Within comprehensive analysis, we examine significance microbiomes, particularly those located intestines, Furthermore, explore impact treatment modalities for cancer, including chemotherapy, immunotherapy, radiotherapy. Additionally, delve into intricate through which intestinal microbes efficacy treatments.

Опубликована: Июнь 25, 2024

Abstract Microbial metabolism upholds a fundamental role in the sustainability of water ecosystems. However, how microorganisms surviving low-concentration substrate environments, including existence emerging compounds interest, remains unclear. In this review, microbial strategies for concentrating, utilizing, and metabolizing low concentration substrates were summarized. Microorganisms develop substrate-concentrating at both cell aggregate levels substrate-limited settings. Following, uptake transport are facilitated by adjusting physiological characteristics shifting affinities. Finally, metabolic pathways, such as mixed-substrate utilization, syntrophic metabolism, dynamic response to nutrient variation, population density-based mechanisms allow efficiently utilize adapt challenging oligotrophic environments. All these will underpin devising new approaches tackle environmental challenges drive ecosystems, particularly managing contaminants (i.e., micropollutants).

Adaptive expression of phage auxiliary metabolic genes in paddy soils and their contribution toward global carbon sequestration

Proceedings of the National Academy of Sciences, Год журнала: 2024, Номер 121(49)

Habitats with intermittent flooding, such as paddy soils, are crucial reservoirs in the global carbon pool; however, effect of phage–host interactions on biogeochemical cycling soils remains unclear. Hence, this study applied multiomics and datasets integrated validation experiments to investigate community potential phages impact sequestration soils. The results demonstrated that soil harbor a diverse abundant repertoire auxiliary metabolic genes (AMGs) associated fixation, comprising 23.7% identified AMGs. successful annotation protein structures promoters further suggested an elevated expression these within their bacterial hosts. Moreover, environmental stressors, heavy metal contamination, cause genetic variation up-regulate fixation AMGs, by significant enrichment related metabolites ( P < 0.05). Notably, findings indicate lysogenic infecting carbon-fixing hosts increased 10.7% under stress. In addition, situ isotopic labeling induced mitomycin-C revealed increasing concentrations, 13 CO 2 emissions from treatment added phage decreased approximately 17.9%. contrast, C-labeled microbial biomass content average 35.4% compared control. These suggest prominently influence cycle, particularly change conditions. This research enhances our understanding cooperation driving amid evolving

Structures and functions of algal glycans shape their capacity to sequester carbon in the ocean

Current Opinion in Chemical Biology, Год журнала: 2022, Номер 71, С. 102204 - 102204

Опубликована: Сен. 22, 2022

Algae synthesise structurally complex glycans to build a protective barrier, the extracellular matrix. One function of matrix is slow down microorganisms that try enzymatically enter living algae and degrade convert their organic carbon back dioxide. We propose lock up in ocean by controlling degradation bacteria other microbes not only while are alive, but also after death. Data revised this review shows accumulation algal underscoring challenge face breach glycan barrier with carbohydrate active enzymes. Briefly we update on methods required certify uncertain magnitude unknown molecular causes glycan-controlled sequestration changing ocean.

Viral infection in the ocean—A journey across scales

PLoS Biology, Год журнала: 2023, Номер 21(1), С. e3001966 - e3001966

Опубликована: Янв. 26, 2023

Viruses are the most abundant biological entity in ocean and infect a wide range of microbial life across bacteria, archaea, eukaryotes. In this essay, we take journey several orders magnitude scales organization, time, space host–virus interactions ocean, aiming to shed light on their ecological relevance. We start from viruses infecting host cells by delivering genetic material seconds nanometer-size membranes, which highjack host’s metabolism few minutes hours, leading profound transcriptomic metabolic rewiring. The outcome lytic infection leads release virions signaling molecules that can reach neighboring millimeters away, resulting population whose heterogeneous level impacts surrounding community for days. These dynamics leave unique biogeochemical fingerprints kilometers over decades. One biggest challenges marine microbiology is assess impact these scales, single cell ecosystem level. Here, argue advent new methodologies conceptual frameworks represents an exciting time pursue efforts propose set important field. A better understanding will inform models global function different climate change scenarios.
