摘要

The aim of this study,is 1-butanol production using CO2 with S.elongatus PCC 7942 culture.The yields of 1-butanolproduced/CO2utilized have been calculated.The maximum concentration of produced 1-butanol is 35.37 mg/L and 1-butanolproduced/CO2utilized efficiency is 92.4.The optimum operational conditions were 30°C temperature,60 W intensity of light,pH=7.1,120 mV redox potential,0.083 m^3/sn flow rate with CO2 and 0.5 mg/l dissolved O2 concentration.Among the enzymes on the metabolic trail of the production of 1-butanol via using S.elongatus PCC 7942 cyanobacteria.At maximum yield;the measured concentrations are 0.016μg/ml for hbd;0.0022μg/ml for Ter and 0.0048μg/ml for AdhE2.The cost analyses necessary for 1-butanol production has been done and the cost of 1 liter 1-butanol has been determined as 1.31 TL/L.
