The present study aims to investigate the potential of recycled corn stover (CS) residues from photo fermentative biohydrogen production (PFHP) reactors for further cycles evaluate its PFHP potential. Results showed hydrogen generation yields 70.32, 63.95, and 16.73 mL/g in 1st, 2nd, 3rd respectively which confirms that cyclic systems produces approximately twice as much single cycles. Total intermediate by-products 2.59 g/L (19% 197% higher) at 24 hours indicate follows acetic acid butyric pathway first cycle. Thermogravimetric analysis (TGA) 3rd, CS solid (biochar) weighed 12.03%, 13.02%, 27.93%, 34.55%. energy, light conversion efficiency (ECE, LCE) was 1.16, 1.15-fold higher than cycle, consequently, research offers a novel way maximize CS's with minimal waste.
