| Abstract (English): |
There are many factors that can affect microalgae growth. In this research, four different groups of experiments were set up in order to determine the influence of different mixing conditions, CO2 concentration and light intensities on Desmodesmus communis growth. The range of CO2 concentration in the air-CO2 mixture was 0-16 v/v%, light intensities ranged between 100 μmol m-2s-1 and 300 μmol m-2s-1. The best biomass productivity and biomass yield of 0.54 g d-1 and 3.53 g l-1 respectively were achieved when mixing was provided by using shaker as well as gas bubbling with air-CO2 mixture of 96:4 v/v% and light intensity of 300 μmol m-2s-1.

| Abstract (Lithuanian): |
Dumblių augimą gali lemti daugelis veiksnių. Šiame tyrime buvo atlikti keturių skirtingų grupių eksperimentai, kuriais buvo siekiama nustatyti skirtingų maišymo sąlygų, CO2 koncentracijos ir šviesos intensyvumo įtaką Desmodesmus communis augimui. CO2 koncentracijos ribos oro-CO2 mišinyje buvo 0-16 v/v%, šviesos intensyvumo ribos 100-300 μmol m-2s-1. Nustatyta, kad didžiausias biomasės augimo greitis ir išeiga - atitinkamai 0.54 g d-1 ir 3.53 g l-1 - buvo gauti, kai maišymas buvo atliekamas purtytuvu, tiekiant 96:4 v/v% oro-CO2 mišinį ir esant 300 μmol m-2s-1 šviesos intensyvumui.
