This review provides a comprehensive analysis of hydrogen production technologies, including fossil fuel-based processes (e.g., thermochemical conversions and steam methane reforming), electrolysis-based routes (alkaline, polymer electrolyte membrane, and solid oxide water), and biological methods (dark fermentation, photofermentation, and biophotolysis), along with emerging photocatalytic and photochemical systems. For each pathway, we critically assess its technological maturity, deployment status, and potential to enhance the share of clean energy in the global renewable energy supply chain. The manuscript also highlights research gaps, prospects, and challenges for numerous upstream hydrogen generation from both biological and non-biological sources, with a specific focus on enhancing efficiency, reducing costs, and improving environmental performance. Photochemical, electrochemical, and photocatalytic hydrogen generation systems utilizing biomass and water as feedstocks have garnered significant attention.</p><p>Technological advances in the downstream enrichment and storage of hydrogen gas are critically evaluated, including opportunities, current challenges, and barriers associated with commercial applications. Metal–organic framework-based pressure swing adsorption, electrochemical hydrogen pumps, and metal hydrides are analyzed for their capacity to achieve high hydrogen purification (~ 99.99%) and enable a scalable storage solution. However, the economic and commercial feasibility of hydrogen production from biomass remains a substantial challenge due to the high production cost ($4.11–$7.45/kg H₂). This can be alleviated by appropriate biomass selection, the development of highly selective catalysts, the integration of different processes, and the application of artificial intelligence-/machine learning-driven models to predict the outcomes for better industrial automation. This study offers insightful information for the selection of highly effective and advanced hydrogen generation, purification, and storage techniques. We conclude with strategic recommendations for technology development, scale-up efficiency, and policy frameworks that can expedite the transition to a sustainable hydrogen economy.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":754,"journal":{"name":"Reviews in Environmental Science and Bio/Technology","volume":"24 4","pages":"957 - 1018"},"PeriodicalIF":10.6,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145435916","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 high H₂S content (up to 45,000 ppm) is considered a significant economic drawback for energy recovery purposes, mainly for the upgrading routes toward biomethane. Despite the potential benefits, the adoption of two-stage biodigestion faces obstacles because of high alkalinization costs. However, the fermentative-sulfidogenic process is promising by producing bicarbonate alkalinity as a by-product of the organic matter oxidation and consuming H⁺ ions through ionized sulfide generation. This pathway mitigates the need for expensive alkalinizing inputs and enhances the biogas energetic value (CH₄ &gt; 80%, H₂S-free), providing favorable conditions for cost-effective and environmentally sustainable upgrading strategies. Moreover, the H₂S- and CO₂-rich biogas produced during the fermentative-sulfidogenic stage must be addressed from an environmental perspective as an “off-gas”, enabling promising biotechnological routes for sulfur and biogenic CO₂ recovery. Although significant progress has been made at laboratory scale, further understanding is needed regarding the role of the fermentative-sulfidogenic step as a biological alkalinity source for methanogenesis. In parallel, developing low-cost and environmentally advantageous strategies to support sulfidogenic activity remains critical. This review elucidates the fermentative-sulfidogenic pathway’s central role in vinasse biodigestion, highlighting its dual potential for biogas upgrading and recovery of valuable by-products such as elemental sulfur and biogenic CO₂.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":754,"journal":{"name":"Reviews in Environmental Science and Bio/Technology","volume":"24 4","pages":"885 - 909"},"PeriodicalIF":10.6,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145435937","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}

To overcome the fluid shear, bacteria often live as assemblages within the matrix, termed biofilms, which is a significant mode of microbial life. One of the established purpose is to decipher how the evolution of multi-cellularity conferred fitness advantage. Investigation into the formation of biofilm have uncovered their remarkable complexity comprising diversity in both composition of resident species and phenotypic traits. In the biofilm development process, several environmental factors, such as nutrients, pH, and oxygen, play a significant role in bacterial phenotypes. Cellular components of bacteria allow them to sense and react to different mechanical stimuli to optimize their function, eventually enhancing bacterial overall fitness. Bacterial cytoskeleton proteins such as FtsZ, MreB, RodZ, MinC, MinD, and MinE present in several bacteria, such as <i>Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa</i> have been shown to be responsible for changing and maintaining the phenotypic form of these bacteria as a response to different environmental factors or stressors. The differential expression of these cytoskeletal proteins help to alter the cell shape and size, leading to pleomorphism. This review entails how the pleomorphism of bacteria within a community influences the cooperative as well as competitive inter-cellular and intra-cellular interactions that regulate the biofilm formation and function. Furthermore, the review highlights the role of local environmental niches in phenotypic switching, to develop stabilized biofilm for environmental and biomedical applications.</p></div>","PeriodicalId":754,"journal":{"name":"Reviews in Environmental Science and Bio/Technology","volume":"24 4","pages":"831 - 860"},"PeriodicalIF":10.6,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145435933","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}

We assess nickel supply forecasts across diverse sectors, with particular emphasis on the rapidly increasing demand associated with rechargeable battery technologies. Concurrently, we examine recent progress in nickel bioleaching, alongside the diversity of acidophilic bacteria and archaea that drive biomining.

This Review illuminates the most efficient sulfur and iron oxidizers, outlining their characteristics, leaching capacities, and current taxonomic nomenclature. We also analyze mechanisms of nickel leaching from sulfides. This includes a critical evaluation of laboratory- and industrial-scale bioprocesses, as well as emerging green methods and their associated microbial consortia.

Traditional methods like composting and anaerobic digestion offer environmental benefits by reducing emissions and recovering valuable resources.
