To date, more than 100 microbial species have been reported to enter the VBNC state under various stressful conditions. In the VBNC state, cells undergo morphological, physiological, and genetic changes, with the mechanisms of VBNC state formation differing among microbial species and stressful conditions. Although the VBNC state has been extensively investigated in the fields of medicine and food safety, research on the VBNC state of pollutant-degrading microorganisms remains limited. Mounting evidence has confirmed the existence of the VBNC state in microorganisms capable of degrading polychlorinated biphenyls (PCBs) and phenol. The resuscitation of VBNC microorganisms, which represent a significant portion of microbial resources, is crucial for the effective microbial remediation of polluted environments. This review provides a comprehensive summary of the formation, characteristics, and mechanisms of the VBNC state in microorganisms. It also outlines various methods for resuscitating VBNC bacteria, with a specific focus on resuscitation-promoting factors (Rpfs). Importantly, from the perspective of environmental bioremediation, this review highlights the potential of VBNC state bacteria, the application of Rpfs in resuscitating VBNC bacteria in polluted environments, and the feasibility of utilizing resuscitated strains as inoculants for environmental bioremediation.","PeriodicalId":10823,"journal":{"name":"Critical Reviews in Environmental Science and Technology","volume":"95 1","pages":"1-24"},"PeriodicalIF":12.6,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910012","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}

In comparison with the biochars derived from wood chips and grass, the biochar produced from nutrient-enriched feedstocks (e.g., sewage sludge, animal manure, microalgae, and wetland plants) contained higher contents of nutrients and showed greater potential for soil application. To achieve the efficient utilization of nutrients in biochar, the behavior of nitrogen (N), phosphorus (P), and potassium (K) during pyrolysis of nutrient-enriched feedstock should be clarified. This study provides a systematic review of the migration and transformation of N, P, and K during the production of biochar derived from nutrient-enriched biomass, with special emphasis on the effects of nutrient-enriched biochar on soil available nutrients. Perspectives and challenges for agricultural applications of biochar are discussed as well. The migration and transformation of N, P, and K are affected by the pyrolysis temperature and the properties of the feedstock during the pyrolysis process. The application of nutrient-enriched biochar could provide additional nutrients, change the physicochemical properties of soil, and modify microbial community to elevate the content of soil available nutrients. Therefore, the production of nutrient-enriched biochar from N/P/K-enriched biomass wastes for soil applications is a promising scheme for sustainable agriculture.","PeriodicalId":10823,"journal":{"name":"Critical Reviews in Environmental Science and Technology","volume":"83 1","pages":"1-19"},"PeriodicalIF":12.6,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143909843","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}

With the advent of novel molecular techniques and meta-omics approaches, it has become more accessible to ascertain the details of viral communities involved in AD systems. This is important as it could help us in monitoring and regulating the factors for improving AD process stability to achieve a selective bio-product like methane.

High temperature (HT) and higher levels of O₃ usually co-exist in the atmosphere. However, few studies have investigated the adverse effects of HT and O₃ co-exposure on cardiovascular system. Therefore, this study aimed to examine the effects of HT and O₃ co-exposure on biomarkers of cardiovascular damage and potential mechanisms. Sixty-four healthy SPF male C57BL/6N mice, aged 8 weeks, were randomly allocated into four groups: control, O₃, HT, and co-exposure (HT+O₃). Mice inhaled filtered air or 1 ppm O₃ at 24 °C or 36 °C, respectively, 4 h/day, for 5 consecutive days. Following the exposure, the biological samples of mice were collected for examination of biomarkers of cardiovascular disorders. Exposure to HT+O₃ exacerbated cardiovascular pathological damage induced by HT or O₃ alone. Compared to the control, the co-exposure group caused significant alterations of cardiovascular biomarkers. Moreover, co-exposure enhanced reduction of <em>Lactobacillus</em> and <em>Ruminococcus</em> and increases in <em>Prevotella</em> and <em>Alistipe</em> abundances induced by either HT or O₃. Moreover, co-exposure also promoted O₃-induced plasma metabolic disorder and these metabolites were enriched in multiple metabolic pathways typified by steroid hormone biosynthesis, biosynthesis of unsaturated fatty acids, and phenylalanine metabolism, among others. Spearman correlation analysis indicated that alterations of gut microbiota were significantly correlated with biomarkers of cardiovascular damage as well as plasma metabolic disorder. Exposure to HT and O₃ leads to cardiovascular damage, which possibly implicates gut microbial dysbiosis and plasma metabolic disorder.</div></div>","PeriodicalId":303,"journal":{"name":"Ecotoxicology and Environmental Safety","volume":"299 ","pages":"Article 118323"},"PeriodicalIF":6.2,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083969","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}

With the increasing use of DINCH in consumer products and industrial materials, the frequency of its detection in the air and human urine has also increased, which has aroused concern about its potential toxicity in food safety. Despite the increasing popularity of DINCH, toxicological studies on this topic are still limited.

Next, the potential hepatotoxic genes associated with DINCH were collected through multiple databases, and a gene network was constructed. Through protein<img>protein interaction, GO enrichment and KEGG pathway analyses, we elucidated the primary mechanism by which DINCH may induce hepatotoxicity. The expression of the selected key genes in related diseases was subsequently validated via the liver cancer database of TCGA and the NASH dataset of GEO. In addition, molecular docking technology and dynamics simulation were used to simulate the interaction and binding ability between DINCH and the core target. Cell experiments verified that DINCH increases hepatotoxicity primarily by upregulating TNF, TP53, and PPARG.

Yet, our understanding of tropical functional diversity and its contribution to global diversity patterns is constrained by data availability. This discrepancy underscores an urgent need to bridge data gaps by incorporating comprehensive tropical root data into global datasets. Here, we provide a database of tropical root characteristics. This new database, TropiRoot 1.0, will be instrumental in evaluating an array of hypotheses pertaining to root functional ecology and plant biogeography, both within the tropics and relative to other global biomes. The data compilation was conducted by the TropiRoot Initiative, in partnership with the Fine-Root Ecology Database (FRED) and the Global Root Trait (GRooT) database, Colorado State University (CSU) and the Smithsonian Tropical Research Institute (STRI). Literature search and data extraction were conducted between 2020 and 2024. Literature was identified using Web of Science, Scopus, and complemented using the expert knowledge of members of TropiRoot. To provide broad environmental and geographical distributions, literature searches included root characteristics (traits) across global change drivers, natural gradients, and from different continents. We adopted FRED standardized data columns and streamlined the format to enhance accessibility for data extraction across various user groups. This optimized framework resulted in a smaller, yet comprehensive datasheet. To make the database compatible with other global root trait initiatives, column identification was standardized following the codes provided by FRED. These efforts culminated in data extracted from 104 new sources, resulting in more than 8000 rows of data (either species or community data). Most of the data in TropiRoot 1.0 include root characteristics such as root biomass, morphology, root dynamics, mass fraction, architecture, anatomy, physiology, and root chemistry. This initiative represents a 30% increase in the currently available data for tropical roots in FRED. TropiRoot 1.0 contains root characteristics from 25 different countries, where seven are located in Asia, six in South America, five in Central America and the Caribbean, four in Africa, two in North America, and 1 in Oceania. Due to the volume of data, when ancillary data were available, including soil data, these data were either extracted and included in the database or its availability was recorded in an additional column.

For text-based observations, we examined all cells to ensure that their content relates to their specific categories.
