Photo-fermentative hydrogen production from lignocellulosic biomass offers a sustainable and carbon-neutral route for bioenergy conversion, providing an effective strategy to mitigate fossil resource depletion and greenhouse gas emissions. Among diverse microbial candidates, purple non‑sulfur bacteria (PNSB) have emerged as promising photosynthetic platforms owing to their broad substrate utilization, intrinsic tolerance to lignocellulose-derived inhibitors, and high hydrogen yields under light-anaerobic conditions. Their metabolic versatility allows dynamic redistribution of carbon and electron fluxes, facilitating efficient energy conversion. Recent progress in metabolic engineering has substantially advanced the hydrogen-producing capacity of PNSB through targeted manipulation of photosynthetic metabolism, redox balance and stress response pathways. Engineering strategies have focused on optimizing pigment biosynthesis to enhance light harvesting, reinforcing redox homeostasis and adenosine triphosphate (ATP) generation, and improving tolerance to environmental stresses such as ammonia, pH, and temperature fluctuations. These efforts have led to engineered strains exhibiting extraordinary improvement in hydrogen yield, stability and robustness. This review provides an overview of the fundamental mechanisms underlying photo-fermentative hydrogen metabolism in PNSB, summarizes recent advances in the metabolic and systems-level engineering strategies, and outlines the prospects of developing strains capable of approaching the theoretical limit of hydrogen yield through integrated engineering strategies, advanced tools such as CRISPR-Cas, and adaptive laboratory evolution methods.
