Effects of Mo⁶⁺ concentration on phototrophic hydrogen production of Rhodobacter sphaeroides were investigated using lactate as the sole carbon source. Results showed that an increase of Mo⁶⁺ from nil to 1000 µg l⁻¹ led to increases in hydrogen yield, maximum production rate, conversion efficiency,...
