Abstract Concerns over environmental issues exists and desire to decrease of their extent, have directed efforts toward green energy production. Growth behavior of Anabaena vaginicola was determined in a photobioreator which illuminated internally (IIPBR) using LED bar light. Excessive heat generated in the IIPBR was taken care of by applying a novel air-cooled system. Further note in experimentation was to find favorable cultivation conditions in the IIPBR for A. vaginicola growth and its lipids production capacity. The following results are expressed: 80 µmol photons m−2 s−1 as light intensity, 0.5 g/l as NaNO3, and 120 ml/min as CO2 amount being expressed in terms of aeration rate. The findings were interpreted in terms of a two-component system where the genes encoded to the relevant proteins are present in cyanobacteria and their expressiveness depends on environmental stress. By determining growth rate constant as 0.11 d−1, the productivity in terms of biomass formation was calculated as 202.6 mg L−1 d−1. While rate of lipids production by the test cyanobacterium is 15.65 mg L−1 d−1. Based on total energy used for IIPBR performance, biomass productivity per unit power input equals to 0.74 g W−1 d−1 and this is in favorable position compared with other photobioreactors. |
