Latest Patents

Najiaowa Yu holds a patent for a "System for hydrogen production under limited aerobic conditions." This invention provides a method for fermentative hydrogen production by utilizing the respiratory interaction between a strictly anaerobic hydrogen-producing bacterium, YUAN-3, and a facultative anaerobic bacterium, PAO1. The co-culturing of these two bacteria allows for hydrogen gas production in a culture medium without requiring anaerobic treatment. The method employs sucrose, lactose, or glucose as carbon sources to promote the growth of YUAN-3 while minimizing substrate competition. Additionally, L-cysteine is added to enhance hydrogen yield and production rate. Using 15 g/L glucose and 5 mmol/L L-cysteine, the method achieved a hydrogen production yield of 1.11 mol-hydrogen/mol-glucose.
