摘要： Photosynthetic hydrogen-producing bacteria play a critical role in photo-fermentation bio-hydrogen production (PFHP) and optimizing the operating conditions is essential for improving hydrogen yield. In this study, corncob was used as raw material for fermentation, Enterobacter hormaechei (EH) was combined with the photosynthetic hydrogen-producing bacterial community HAU-M1 to form a new bacterial community, HAU-M2, for hydrogen production via PFHP. Response surface method (RSM) model and a genetic algorithm optimized neural network (GANN) model were used and compared to optimize the operating conditions of the PFHP process. The results showed that the GANN model showed enhanced optimization abilities. Under optimal conditions, the cumulative hydrogen yield was 51.96 mL/g TS. The energy recovery efficiency in the GANN experimental group (3.59 +/- 0.12%) increased by 55% compared to the control group (2.31 +/- 0.13%). This study provides valuable insights and references for the resource utilization of agricultural waste and the clean production of renewable energy.
