对影响光合茵群利用丁酸产氢的主要因子:初始细胞浓度、温度、初始pH值、光照强度和丁酸浓度进行了研究.结果表明,光合茵群在初始细胞浓度0.2～O.3 g/L,温度30~40℃,PH 6.0～9.0,光照强度2000～8000 Lx,丁酸浓度6～30 mmol/L的范围内均可以保持较高的产氢效率.当初始细胞浓度为0.3 g/L、温度30℃、初始PH 7.0、光照强度为4000 Lx、丁酸浓度为30 mmol/L时该光合茵群具有最大产氢量364 mL,最大产氢效率5.4 mol-H_2/mol-丁酸和最大产氢速率22.2 mL/L/h.

The factors affecting hydrogen production from butyrate by photosynthetic bacteria group,such as initial ceiI concentration, temperature, initial pH value, light intensity and butyrate concentration were investigated. The results showed that photosynthetic bacteria group maintained high production efficiency when initial cell concentration was between 0. 2 and 0.3 g/L, temperature was 30~40 ℃,initial pH value was in the range of 6.0～9.0, light intensity was 2000～8000 Lx and initial butyrate concentration was 6～30 mmol/L. The maximum cumulative hydrogen production quantity of 364 mL,maximum hydrogen yield of 5.4 mol-H_2/mol-butyrate, maximum hydrogen production rate of 22.2 mL/L/h were obtained when initial cell concentration, temperature , initial pH value, light intensity and butyrate concentration were 0. 3 g/L, 30 ℃, 7.0, 4000 Lx and 30 mmol/L, respectively.
