The investigation into the cultivation conditions
of two robust algae Chlorella sp. and Scenedesmus sp.
strains extracted from Lithuanian lakes has shown that
the best results of the algae biomass growth could be
achieved when cultivation medium BG11 is modified
with urea or a decreased concentration of NaNO3 and
the growing biomass is aerated under CO2
(concentration of 24 %). The fatty acid composition
of oil in both cultures has conformed to the
requirements and conclusion can be made that it is a
promising resource for biofuel production. Besides,
both algae strains Chlorella sp. and Scenedesmus sp.
could be used in wastewater treatment as an
additional removal agent of pollutants such as
nitrogen and phosphorus.
