摘　　要：研究了猪粪污水条件下,光照度对红假单胞菌(Rhodobactersphaeroides)1.1737菌株进行光合产氢的影响,结果表明球形红假单胞菌的产氢活性随着光照度的增大而增大,在高于1000lux光照度下比在低于1000lux光照度下产氢活性显著提高。在1600lux光照度下产氢速率达到最大,而在1200、1600和2000lux光照度下产氢量差别相对比较小,说明光照度增加到一定程度后对细菌产氢活性的影响将会逐渐减少,对产氢量和产氢速率的提高无明显作用。The influence of light intensity on （Rhodobacter sphaeroides） 1. 1737-thus hydrogen production was investigated under the condition of pig dejecta wastewater. It turns out that, with the increase of light intensity, the activity of Rhodobacter sphaeroides is getting stronger. When the light instensity is above 1000 lux, its activity can be improved drastically; When it comes to 1600 lux, the rate of hydrogen production reached the biggest value. As to 1200 lux, 1600 lux and 2000 lux, the difference in the amount of hydrogen production is relatively low. It indicates that the influence on activity of hydrogen production would decline if light intensity is increased to a certain degree, the influence on the hydrogen production activity of the bacteria would reduce, so there is no obvious influence on the amount and rate of hydrogen production.
