Abstract Algae-bacteria interactions play an essential role in the transformation of complex organics microalgal-bacterial granular sludge (MBGS), but intrinsic removal mechanisms have not been well understood. This study thus attempted to investigate performance and real municipal wastewater MBGS process. The results showed that could be effectively disposed during day-night cycles by MBGS, with process significant impacted influent C/N ratio. Further metagenomic metatranscriptomic analyses revealed upregulated gap2 gpmA genes glycolysis enhanced conversion CO2 mediated Chlorophyceae Acidobacteriae/Sumerlaeia/Fimbriimonadia, while petH gene NADPH synthesis Cyanobacteria strengthened fixation into biomass. Meanwhile, functional amyA starch metabolism Actinobacteriota was upregulated, along gldA glycerolipid through Chloroflexia/Verrucomicrobiae. Moreover, a close symbiotic relationship between Desulfobacterota I identified, which played crucial fatty acid decomposition. offers new insights degradation via symbiosis, also gains basic knowledge on carbon cycle natural water ecosystems symbiosis.

Abstract Wastewater treatment plants are the major energy consumers and significant sources of greenhouse gas emissions, among which biological nitrogen removal wastewater is an important contributor to carbon emissions. However, traditional heterotrophic denitrification still has problems excessive residual sludge requirement external sources. Consequently, development innovative low-carbon nitrate technologies necessary. This review outlines key roles sulfur autotrophic hydrogen in treatment. The discovered nitrate/nitrite dependent anaerobic methane oxidation enables sustainable emission reduction by utilizing available situ . Photosynthetic microorganisms exhibited a promising potential achieve carbon-negative removal. Specifically, algal-bacterial symbiosis system photogranules offer effective prospective options for Then, emerging technology photoelectrotrophic underlying photoelectron transfer mechanisms discussed. Finally, we summarize prospect these technologies, highlighting that solar-driven area future guiding significance design systems.

Abstract Interactions between algae and bacteria are pivotal in transforming complex organics for microalgal-bacterial granular sludge process, but the intrinsic removal mechanisms have not been well understood. Here, we investigate by which removed from municipal wastewater. Complex can be disposed during day-night cycles, significantly impacted carbon-to-nitrogen ratio influent. Upregulated gap2 gpmA genes enhanced conversion of into CO 2 , mediated interactions Chlorophyceae with Acidobacteriae / Sumerlaeia Fimbriimonadia upregulated petH gene Cyanobacteria strengthened fixation biomass. The breakdown starch, glycerol, fatty acid were depended on Actinobacteriota Chloroflexia Verrucomicrobiae Desulfobacterota I respectively. These findings provide new insights through symbiosis contribute to our understanding carbon cycle natural aquatic ecosystems.

Abstract Co-aggregation of anaerobic microorganisms into suspended microbial biofilms (aggregates) serves ecological and biotechnological functions. Tightly packed aggregates metabolically interdependent bacteria archaea play key roles in cycling carbon nitrogen. Additionally, applications, such as wastewater treatment, provide a complete metabolic network to convert complex organic material. Currently, experimental data explaining the mechanisms behind co-aggregation anoxic environments is scarce scattered across literature. To what extent does this process resemble aerobic environments? Does limited availability terminal electron acceptors drive mutualistic relationships, contrary commensal relationships observed oxygen-rich And do co-aggregating archaea, which depend on each other harvest bare minimum Gibbs energy from energy-poor substrates, use similar cellular those used by pathogenic that form biofilms? Here, we an overview current understanding why how mixed communities co-aggregate discuss potential future scientific advancements could improve study aggregates. Key points • Metabolic dependency promotes aggregation Flagella, pili, adhesins role formation Cyclic di-GMP/AMP signaling may trigger polysaccharides production anaerobes
