光合细菌产氢过程的碳源代谢实验研究

his paper studied the influence of different carbon sources on the growth of photosynthetic bacteria and the impact of hydrogen production,using a mixed hydrogen-producing photosynthetic bacteria as reaserch object. The results showed that photosynthetic grew rapidly by using small molecule acid and alcohol, such as acetic acid, butyric acid, pyruvic acid. Acetic acid is the best carbon source for bacteria growth and carbon substrates for hydrogen production in all small molecule acid and alcohol. The best addition of acetic acid is 80 mmmol/L as the growth carbon substrates and is 40 mmol/L as the hydrogen producetion substrates.These perhaps provide a reference and basis for the research of photosynthetic bacteria growth and hydrogen production mechanism.
