Determining the biotic and abiotic factors that influence marine microbial growth and community structure is critical for understanding global biogeochemical cycles. Here, we present vertical profiles of intracellular PPIX and four derivative products (Chlorophyll-<em>a</em>/<em>b</em> and Pheophytin-<em>a</em>/<em>b</em>) from two coastal sediment cores, alongside ancillary geochemical and 16S rRNA microbial community data. Our findings indicated that PPIX is present in the natural sediment environment and displays a decreasing trend with depth, revealing a significant positive correlation with both organic matter and microbial abundance. Co-occurrence networks revealed that the environmental distribution of PPIX was positively correlated with the microbial porphyrin producer (high genetic completeness), but negatively correlated with auxotrophs (absence or low genetic completeness). It emphasized the critical role of PPIX as a biological molecule involved in key physiological processes. These results suggest that PPIX is a prominent component of the shared extracellular metabolite pool, especially in anoxic marine sediments where it exists at physiologically relevant concentrations for microbial metabolism. This study highlighted the significance of PPIX in microbial ecology and its potential impact on biogeochemical cycles in marine sedimentary environments.</div></div>","PeriodicalId":15788,"journal":{"name":"Journal of Environmental Sciences-china","volume":"156 ","pages":"Pages 712-724"},"PeriodicalIF":5.9,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143835092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Our study discovered that light induced generation and accumulation of more toxic brominated organic compounds (Br-org) in lettuce leaves under the stress of acetaminophen (ACE) than that without light, as evidenced by an increase in C-Br bond intensity in FTIR analysis. This result can be explained by the oxidation of bromide ions (Br<sup>-</sup>) by reactive species (ROS and <sup>3</sup>Chl*) of chloroplast into reactive bromine species (RBS).
