Abstract

The global shift towards renewable energy sources highlights the urgent need for sustainable hydrogen production, with photo-fermentative hydrogen evolution (PFHP) emerging as a promising solution. This review addresses the challenges and opportunities in optimizing PFHP, specifically the role of photosynthetic bacteria (PBS) in utilizing sunlight for hydrogen production. We focus on the key factors influencing PFHP, including light intensity, reactor design, substrate selection, carbon-to-nitrogen ratio, metal ions, temperature, pH, charge transfer and genetic engineering. Additionally, we explore recent advances in techniques such as immobilization, nanoparticles, biochar, and co-culturing to enhance hydrogen production efficiency. By synthesizing the latest research, this review provides new insights into improving PFHP processes, offering strategies for more efficient biohydrogen production. This work contributes to the development of sustainable hydrogen production technologies, advancing the potential for biohydrogen as a clean energy source.
