BIOMASS PRODUCTION Chlorella vulgaris BUITENZORG USING SERIES OF BUBBLE COLUMN PHOTO BIOREACTOR WITH A PERIODIC ILLUMINATION

Chlorella vulgaris Buitenzorg cultivation using three bubble column photo bioreactors arranged in series with a volume of 200 mL for 130 hours shows an increase of biomass production of Chlorella vulgaris Buitenzorg up to 1.20 times and a decrease of the ability of CO2 fixation compared to single reactor at a periodic sun illumination cycle. The operation conditions on cultivation are as following: T, 29.0 degrees C; P,1 atm.; U-G, 2.40 m/h; CO2, 10%; Benneck medium; and illumination source by Phillip Halogen Lamp 20W /12V/ 50Hz. Other research parameters such as microbial carbon dioxide transferred rate (qco(2)), CO2 transferred rate (CTR), energy consumption for cellular formation (E-x) and cultural bicarbonate species concentration [HCO3] also give better results on series of reactor.
