“…It has been shown that polysaccharides from plants are the main energy source of Bacteroides , so feeding polysaccharides can promote the proliferation of Bacteroides ( Zafar and Saier, 2021 ). Actinobacteria play an important role in the turnover of organic matter and carbon cycle, such as decomposing cellulose ( Wang et al, 2023 ). At the same time, the beneficial bacteria of Actinobacteria often help the body to improve digestive problems and enhance immunity ( Xiao et al, 2020 ).…”

“…Additionally, Actinobacteria and Nitrospirae are also found to be active in DOM transformation. Their active roles in DOM transformation have been reported recently, , but their contributions and target substrates are unclear. Here, we highlight Actinobacteria’s roles in the oxygenation of aldehyde or oxo groups of DOM and Nitrospirae’s role in DOS oxidation and DOM hydroxylation.…”

Understanding the reaction mechanism of dissolved organic matter (DOM) during wastewater biotreatment is crucial for optimal DOM control. Here, we develop a directed paired mass distance (dPMD) method that constructs a molecular network displaying the reaction pathways of DOM. It couples direction inference and PMD analysis to extract the substrate−product relationships and delta masses of potentially paired reactants directly from sequential mass spectrometry data without formula assignment.Using this method, we analyze the influent and effluent samples from the bioprocesses of 12 wastewater treatment plants (WWTPs) and build a dPMD network to characterize the core reactome of DOM. The network shows that the first step of the transformation triggers reaction cascades that diversify the DOM, but the highly overlapped subsequent reaction pathways result in similar effluent DOM compositions across WWTPs despite varied influents. Mass changes exhibit consistent gain/loss preferences (e.g., +3.995 and −16.031) but different occurrences across WWTPs. Combined with genome-centric metatranscriptomics, we reveal the associations among dPMDs, enzymes, and microbes. Most enzymes are involved in oxygenation, (de)hydrogenation, demethylation, and hydration-related reactions but with different target substrates and expressed by various taxa, as exemplified by Proteobacteria, Actinobacteria, and Nitrospirae. Therefore, a functionally diverse community is pivotal for advanced DOM degradation.
