Along with the popularization of high-throughput technologies, community-wide microbial source-tracking methods have been actively developed in recent years. This study aimed to construct a comprehensive fecal microbiome database for community-wide microbial source tracking and apply the database to identify contamination sources in the Miho River, South Korea. Total DNA was extracted from the samples, and the 16 S rRNA gene was amplified to characterize the microbial communities. The fecal microbiome database was validated by developing machine-learning models that predict host species based on microbial community structure. All machine learning models developed in this study showed high performance, where the area under the receiver operating characteristic curve was approximately 1. Community-wide microbial source tracking results showed a higher contribution of fecal sources to the contamination of the main streams after heavy rain. In contrast, the contribution of fecal sources remained comparatively stable in tributaries after rainfall. Considering that farms are more concentrated upstream of tributaries compared to the main streams, this result implies that the pathway for manure contaminants to reach the main streams could be groundwater rather than surface runoff. Systematic monitoring of the water quality, which encompasses river water and groundwater, should be conducted in the future. In addition, continuous efforts to identify and plug abandoned wells are necessary to prevent further water contamination.</p></div>","PeriodicalId":467,"journal":{"name":"Applied Biological Chemistry","volume":"67 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://applbiolchem.springeropen.com/counter/pdf/10.1186/s13765-024-00915-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141444746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ogaza extracts were obtained in various solvents, such as 70% ethanol, 70% methanol, and water. The anti-inflammatory activity was estimated by evaluating nitric oxide production in lipopolysaccharide (LPS)-induced RAW 264.7 cells treated with the extracts. The 70% ethanol extract (EO) showed the most effective anti-inflammatory activity, inhibiting nitric oxide production by approximately 50% and downregulating iNOS expression. The 70% ethanol extract was further fractionated into three partial subfractions by preparative LC to identify the anti-inflammatory compounds. Assessment of the anti-inflammatory activity of each subfraction revealed that the third subfraction (E-F3) showed the highest inhibitory activity against nitric oxide. E-F3 effectively suppressed iNOS expression. Subsequently, liquid chromatography-tandem mass spectrometry (LC-MS/MS) and multivariate statistical analyses were performed to identify the compounds that significantly contributed to the anti-inflammatory activity of the Ogaza extract. Fourteen and 16 compounds in the negative- and positive-ion modes, respectively, were identified as significant constituents of Ogaza. Compounds like quercetin, hyperoside, acanthoside D, oleanolic acid, and scopoletin were identified as potential anti-inflammatory components in Ogaza extract.
