  • PROJ Organic Carbon Transformation by Marine Heterotrophic Bacteria Adapting to Hypoxia

    Quanrui Chen, ,2024.05.29

    Description

    The global increase in hypoxic zones necessitates a comprehensive understanding of marine organic carbon cycling dynamics under hypoxic conditions to evaluate their impact on global carbon cycles and ecosystem health. This study, conducted in the seasonal hypoxia zone of the Yangtze River Estuary, investigates the effects of deoxygenation on the microbial utilization of algal-derived organic carbon. Through culture experiments and molecular analyses, the research explores the adaptability of heterotrophic bacterial communities in response to hypoxia, focusing on changes in composition and metabolic pathways. High-throughput 16S rDNA sequencing is used to analyze shifts in microbial community dynamics and their role in organic carbon transformation. The study aims to provide new insights into the complex interactions between microbial communities and organic matter cycling under hypoxic conditions, informing strategies for managing marine ecosystems amidst global change.

  • PROJ Multi-kingdom microbiota analyses identify bacterial-fungal interactions and biomarkers of colorectal cancer across cohorts

    Ningning Liu, Shanghai Jiao Tong University,2020.12.02

    Description

    Despite recent progress in our understanding of the association between the gut microbiome and colorectal cancer (CRC), multi-kingdom gut microbiome dysbiosis in CRC across cohorts is unexplored. We investigated four-kingdom microbiota alterations using CRC metagenomic datasets of 1,368 samples from 8 distinct geographical cohorts. Integrated analysis identified 20 archaeal, 27 bacterial, 20 fungal and 21 viral species for each single-kingdom diagnostic model. However, our data revealed superior diagnostic accuracy for models constructed with multi-kingdom markers, in particular the addition of fungal species. Specifically, 16 multi-kingdom markers including 11 bacterial, 4 fungal and 1 archaeal feature, achieved good performance in diagnosing patients with CRC (area under the receiver operating characteristic curve (AUROC) = 0.83) and maintained accuracy across 3 independent cohorts. Coabundance analysis of the ecological network revealed associations between bacterial and fungal species, such as Talaromyces islandicus and Clostridium saccharobutylicum. Using metagenome shotgun sequencing data, the predictive power of the microbial functional potential was explored and elevated D-amino acid metabolism and butanoate metabolism were observed in CRC. Interestingly, the diagnostic model based on functional EggNOG genes achieved high accuracy (AUROC = 0.86). Collectively, our findings uncovered CRC-associated microbiota common across cohorts and demonstrate the applicability of multi-kingdom and functional markers as CRC diagnostic tools and, potentially, as therapeutic targets for the treatment of CRC.

  • PROJ Methylparaben changes the community composition, structure and assembly processes of free-living bacteria, phytoplankton and zooplankton

    丽君 周, 中国科学院南京地理与湖泊研究所,2024.05.13

    Description

    Parabens are widely used as preservatives and bactericides in food, pharmaceuticals, and cosmetics, and are commonly found as contaminants in river and lake ecosystems. However, there are few studies on the effects of parabens on phytoplankton, zooplankton, and bacterial communities in aquatic environment.
