Traditional animal hide/skin resource utilization technologies face serious challenges in the aspect of production efficiency and environmental sustainability. Enzymatic collagen fiber purification processing is thought to be one of the most promising technologies that can minimize the use of chemicals and energy, reduce CO2-eq emissions, and achieve sustainable development of animal hide/skin reutilization. However, enzymatic processes have not been well accepted for industrial-scale applications in factories so far. In this review, recent progress and challenges of enzymatic collagen fiber purification processing were comprehensively overviewed in the aspect of the key mechanisms and technologies of enzyme application. Recommendations for the direction of enzyme selection and development were put forward, which is expected to pave the way for the industrial-scale application of enzymes in animal hide/skin collagen fiber purification processing.","PeriodicalId":258,"journal":{"name":"Bioresource Technology","volume":" ","pages":"131955"},"PeriodicalIF":9.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142790592","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}

The results showed that both destroyed the performance of AGS systems, with PVC-MPs achieving this by disrupting the AGS structure, while PLA-MPs mainly by causing the expansion of filamentous bacteria induced through the stimulation by lactic acid metabolite (R0: 5.52 ± 0.49 μg/L; RPLA5: 11.67 ± 0.56 μg/L). Moreover, both MPs inhibited nitrogen removal by disrupting partial nitrification and endogenous denitrification and suppressed key microbes such as Candidatus Competibacter and Nitrosomonas. Metabolic pathway analysis and molecular docking have further confirmed the mechanisms by which MPs affect critical metabolic pathways and key enzymes. Consequently, the hazards of biodegradable MPs to the stable operation of sewage treatment plants should also be of concern.","PeriodicalId":258,"journal":{"name":"Bioresource Technology","volume":" ","pages":"131917"},"PeriodicalIF":9.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142764831","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}

A blend of optimal concentrations of fractions was identified as the most stimulating extract, increasing the root elongation by 25 %. When applied to tomato plants and monitored using high-throughput plant phenotyping, the blend displayed a 25 % reduction in mineral fertilizer use. Metabolomic analysis of the tomato plants showed significantly enhanced carbon and nitrogen metabolism in the leaves.

Then, the physiological properties of cells and the interactions between nitrogen and carbon metabolism under antibiotic stress were discussed, particularly within the anammoxosome. The microbial community evolution and the development and transfer of antibiotic resistance genes (ARGs) were further analyzed to reveal the resistance mechanisms of anammox. To address the limitations imposed by antibiotics, the development of bio-augmentation and combined processes based on molecular biology techniques, such as bio-electrochemical systems (BES), has been suggested. This review offered new insights into the mechanisms of antibiotic inhibition during the anammox process and aimed to advance their engineering applications.","PeriodicalId":258,"journal":{"name":"Bioresource Technology","volume":" ","pages":"131950"},"PeriodicalIF":9.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142794110","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}
