In this three-year study, comammox Nitrospira consistently dominated both abundance and activity in an acidic nitrifying reactor (pH = 6.3-6.8), as revealed by metagenomic and cDNA-based 16S rRNA sequencing. Batch tests demonstrated their decent nitrification down to pH 4.7, while ceasing at pH 4.2. Genome-centric metatranscriptomics revealed that comammox Nitrospira upregulated a Rh-type ammonium transporter to enhance substrate uptake under acidic conditions. Active proton transport, mediated by NADH dehydrogenases and F-type ATPase, was identified as a primary strategy for maintaining pH homeostasis in comammox Nitrospira. Genes associated with carbon acquisition, chemotaxis, and DNA repair were upregulated at low pH, suggesting these processes play roles in acid adaptation. These findings enhance the understanding of ecological roles and adaptive mechanisms of comammox bacteria in acidic environments.","PeriodicalId":258,"journal":{"name":"Bioresource Technology","volume":" ","pages":"131986"},"PeriodicalIF":9.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142851829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the degradation mechanisms of sulfonamides (sulfadiazine, sulfamethoxazole) and quinolones (ciprofloxacin, norfloxacin) during thermally activated persulfate (TAP) treatment. The main degradation mechanisms for sulfonamides involved S-N bond cleavage and -NH2 oxidation mediated by sulfate and hydroxyl radicals, whereas quinolone degradation occurred primarily through piperazine ring cleavage facilitated by a single linear oxygen.

FAME analysis was performed under optimal lipid-producing conditions (10 ppm caffeine, 5 ppm IAA). IAA upregulated key metabolic pathways, increasing secondary metabolites in Desmodesmus and Chlorella. In summary, the modeling results are key for improving system performance, guiding parameter selection to enhance caffeine removal by Desmodesmus.

Further analysis highlighted that ADS-B's superior physicochemical properties enhanced the conversion of butyrate to caproate and facilitated the colonization of key microorganisms, such as <ce:italic>Terrisporobacter</ce:italic> and <ce:italic>Clostridium</ce:italic>, essential for caproate production.
