Pathways of nutrient uptake by microorganisms, such as nitrogen and sulfur metabolism, were closely linked to cellulase activity. The study also revealed that cellulase activity was constrained by the availability of sulfur and nitrogen, with optimal levels enhancing microbial cellulase activity. These findings provide insights into the microbial mechanisms underlying SBP degradation and the role of AA-pretreatment in enhancing enzymatic hydrolysis.</div></div>","PeriodicalId":381,"journal":{"name":"Journal of the Taiwan Institute of Chemical Engineers","volume":"175 ","pages":"Article 106257"},"PeriodicalIF":5.5,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144633831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
