This comprehensive review investigates the production, composition, and mechanisms of action of PHs in promoting plant growth and stress resilience. PHs are obtained through enzymatic hydrolysis of protein-rich waste, yielding mixtures of amino acids and bioactive peptides. Commercial PHs exhibit diverse effects, including enhanced nutrient uptake, abiotic stress tolerance, and crop yield in various agricultural and horticultural species. The biostimulant activity of PHs is attributed to multiple interconnected pathways, such as hormone-like signalling, antioxidant defense, osmotic regulation, and gene expression modulation. Moreover, PHs influence the plant microbiome, potentially contributing to improved stress adaptation. Foliar and root application methods, along with factors like pH and transporters, govern PH absorption and translocation in plants. Transcriptomic and proteomic studies have provided insights into the molecular mechanisms underlying PH-mediated growth promotion and stress mitigation. Future research should focus on optimizing PH formulations, exploring synergies with other biostimulants, and elucidating the role of plant-microbe interactions. By harnessing the potential of these sustainable compounds, PH biostimulants offer a promising approach to enhance agricultural productivity and resilience in the face of global challenges.</div></div>","PeriodicalId":8947,"journal":{"name":"Bioresource Technology Reports","volume":"32 ","pages":"Article 102333"},"PeriodicalIF":0.0,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145321578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study assesses the techno-economic feasibility of producing high-value products from pineapple leaf waste through a novel single-step hydrothermal process. Four scenarios were evaluated: (i) recovery of cellulose nanofibers (CNF), xylooligosaccharides (XOS), and polyphenol powder (PP) (CNF + XOS + PP), (ii) CNF + XOS, (iii) CNF + PP, and (iv) CNF only. For a 5 TPH plant operating 180 days annually (base case), the CNF + XOS + PP scenario yielded a net present value (NPV) of US$177.2 million, an internal rate of return (IRR) of 38.3 %, and a payback period (PBP) of 3.4 years. The CNF + PP scenario achieved even higher profitability with an NPV of US$196.5 million, an IRR of 40.8 %, and a PBP of 2.9 years. Sensitivity analysis revealed that operational duration and CNF price are the most influential factors. Multiproduct scenarios demonstrated significantly higher viability than CNF-only production (NPV US$53.6 million). The CNF-only case remains profitable if the minimum selling price (MSP) of CNF exceeds US$32.8/kg. Breakeven analysis indicated MSPs of US$20/kg for both CNF and XOS in the CNF + XOS + PP scenario, and US$30/kg (CNF) and US$15/kg (PP) in the CNF + PP scenario.

The good settleability of ABGS in R2 can be attributed to the enrichment of EPS-secreting bacteria (Proteobacteria) and greater algal richness. Key salt-tolerant bacteria involved in organic carbon metabolism, phosphorus removal, and nitrification-denitrification were well preserved in R2.
