Energy shortages have hindered global economic development.By utilizing waste as a substrate for microbial fermentation,hydrogen production can transform waste into a valuable resource,significantly reducing the cost of hydrogen production and addressing a significant hurdle in achieving large-scale production of microbial hydrogen.This approach has significant potential for future hydrogen-production applications.Two-stage indirect photohydrolysis has recently emerged as a promising and efficient method for hydrogen production using cyanobacteria and green algae.However,this method cannot be directly applied to organic wastewater for hydrogen production.In contrast,dark fermentation by bacteria,particularly ethanol-type fermentation,is highly efficient for producing hydrogen.Therefore,the combination of the indirect photohydrolysis of algae and dark fermentation by bacteria is expected to significantly enhance the hydrogen-production capacity of organic wastewater,laying the groundwork for future large-scale microbial hydrogen production.This study reviews the main types and technical principles of microbial hydrogen production from waste,available waste types,research progress in the microbial hydrogen-production process,strategies to improve the hydrogen-production rate,and challenges faced during industrialization.Future research directions for microbial-waste hydrogen production are also proposed.The aim of this study is to provide a valuable reference for large-scale biological hydrogen-production research.
