Abstract
Growth characteristics of two strains of microalgae in bubble column photobioreactors
were investigated under different cultivation conditions. Chlorella vulgaris and Gloeothece
membranacea were cultivated in luminescent acrylic photobioreactors at different seed
culture densities. Luminescent acrylic photobioreactors in blue, green, yellow, orange,
and red colours capable of spectral conversion of light were used. The results indicated
that the red luminescent photobioreactor enhanced biomass production in both strains
of microalgae while pigmentation was induced under different light colours. Green
light promoted chlorophyll production in C. vulgaris however chlorophyll production
in G. membranacea cultures was less influenced by the light condition or culture density.
Phycobiliproteins were the dominant pigments in G. membranacea and red light favoured
synthesis of these pigments.
