Microbial Roles in Dissolved Organic Matter Transformation in Full-Scale Wastewater Treatment Processes Revealed by Reactomics and Comparative Genomics

Environmental Science & Technology, Journal Year: 2021, Volume and Issue: 55(16), P. 11294 - 11307

Understanding the degradation of dissolved organic matter (DOM) is vital for optimizing DOM control. However, microbe-mediated transformation during wastewater treatment remains poorly characterized. Here, microbes and along full-scale biotreatment processes were simultaneously characterized using comparative genomics high-resolution mass spectrometry-based reactomics. Biotreatments significantly increased DOM's aromaticity unsaturation due to overproduced lignin polyphenol analogs. was diversified by over five times in richness, with thousands nitrogenous sulfur-containing compounds generated through oxidoreduction, functional group transfer, C–N C–S bond formation. Network analysis demonstrated microbial division labor transformation. their roles determined traits rather than taxa. Specifically, network module hubs exhibited rapid growth potentials broad substrate affinities but deficient xenobiotics-metabolism-associated genes. They mainly correlated liable consumption its recalcitrant compounds. In contrast, connectors peripherals potential degraders slow growth. showed specialized associations fewer molecules probably fed on metabolites hub microbes. Thus, developing technologies (e.g., carriers) selectively enrich peripheral consequently decouple may advance removal.

Metagenomic and machine learning-aided identification of biomarkers driving distinctive Cd accumulation features in the root-associated microbiome of two rice cultivars

Abstract Developing low-cadmium (Cd) rice cultivars has emerged as a promising avenue for food safety in Cd-contaminated farmlands. The root-associated microbiomes of have been shown to enhance growth and alleviate Cd stress. However, the microbial taxon-specific resistance mechanisms underlying different accumulation characteristics between remain largely unknown. This study compared low-Cd cultivar XS14 hybrid YY17 with five soil amendments. results showed that was characterized by more variable community structures stable co-occurrence networks soil-root continuum YY17. stronger stochastic processes assembly (~25%) rhizosphere than (~12%) suggested may higher changes properties. Microbial machine learning models jointly identified keystone indicator microbiota, such Desulfobacteria Nitrospiraceae Meanwhile, genes involved sulfur cycling nitrogen were observed among microbiome these two cultivars, respectively. Microbiomes root diversity functioning, significant enrichment functional related amino acid carbohydrate transport metabolism, cycling. Our findings revealed differences similarities communities associated well bacterial biomarkers predictive Cd-accumulation capacity. Thus, we provide new insights into recruitment strategies under stress highlight utility offering clues enhancing crop resilience stresses future.

Metaproteomics, metagenomics and 16S rRNA sequencing provide different perspectives on the aerobic granular sludge microbiome

Water Research, Journal Year: 2023, Volume and Issue: 246, P. 120700 - 120700

Published: Oct. 6, 2023

The tremendous progress in sequencing technologies has made DNA routine for microbiome studies. Additionally, advances mass spectrometric techniques have extended conventional proteomics into the field of microbial ecology. However, systematic studies that provide a better understanding complementary nature these 'omics' approaches, particularly complex environments such as wastewater treatment sludge, are urgently needed. Here, we describe comparative metaomics study on aerobic granular sludge from three different plants. For this, employed metaproteomics, whole metagenome, and 16S rRNA amplicon to same granule material with uniform size. We furthermore compare taxonomic profiles using Genome Taxonomy Database (GTDB) enhance comparability between approaches. Though major taxonomies were consistently identified samples, composition obtained by omics varied significantly at lower levels, which impacts interpretation nutrient removal processes. Nevertheless, demonstrated genera all cover majority protein biomass. established data contig classification pipeline publicly available, provides valuable resource further metabolic processes sludge.
