Microalgae are
photosynthetic microorganisms which are recently grown to produce biomass for food, pharmaceutical, dye, and bioenergy industries. Microalgae are the
carbon source found in crude oil and natural gas. Over the years, there
have been several advances in the design and operation of closed photobioreactors
for microalgal cultures based on new reactor geometries as well as optimized aeration
and mixing strategies. Closed photobioreactors ensure heat
control, and high production through effective use of high-intensity light and prevent contamination in microalgae
production. One of the most important factors that
control cell growth in a photobioreactor is light availability. In this study,
cultivation of Chlorella sp., as
microalgae were performed in a specially
designed photobioreactor for productivity analysis and the pigment capacity
analysis. The applied light energy was kept constant while applying either
continuous or intermittent lighting during the growth of microalgae. The
cultivation parameters were tested to find the optimal light mode as the continuous
light or 12h light/ 12h dark cycle to maximize pigment amount. In order to
determine the pigment amount in the cultivated algae extraction was done. Then
by using UV spectrophotometer amount of chlorophyll a and b were determined in
the obtained extracts.
