In this study, different parameters were optimized in order to increase the CO2 fixation rate and biomass production of Leptolyngbya sp., which is a new flue gas resistant cyanobacteria. Leptolyngbya sp. was stimulated with 3-Indoleacetic acid (IAA) and Viburnum opulus (VO) growth stimulators to provide resistant against increasing flue gas concentrations. The maximum biomass was obtained 1.3 times higher than of control culture with 3.788 g L-1 in BG11 + 5% Thermal Power Plant Cooling Water + 0.5 g L-1 IAA + 2.5 g L-1 VO culture media, at pH 8, at 35 +/- 2 degrees C, at 0.1 g L-1 initial biomass concentrations, with 25 mu mol m(-2) s(-1) (24: 0, light: dark photoperiod) in 14 days of incubation period. The maximum productivity (Pmax) was 0.263 g L-1 d(-1), the maximum specific growth rate was 0.26 d-1 and the maximum CO2 fixation rate was 48.2 mgCO(2) d(-1). It was determined that compared to control culture, Leptolyngbya sp., could provide more biomass and capable of fixing more CO2 rates with the help of IAA and VO growth stimulators at increasing flue gas emissions.
