| description | For years, Chlorella sp, have been proven to be one of the candidates in
producing abundant amounts of algal biomass. In this study, the fabrication of a new
reactor was done and performance of Halochlorella rubescens, microalgae under genus
Chlorella sp. in producing high cell mass was studied. Microalgae cell activation profile
in three different cultivation volumes (500 mL, 1 L and 5 L) at normal cultivation mode
and effect of pH towards the algae growth kinetic in a fabricated 15-L photobioreactor
was investigated. 500 mL culture recorded highest biomass concentration and biomass
productivity of 2.493 g/L and 0.183 g DW L-1 d -1. Dilution of cell lines and inoculum
age are found to have notable effects towards microalgae growth. Highest biomass
concentration and biomass productivity,1.689 g/L and 0.1043 g DW L-1 d -1 was
recorded when the microalgae cultivated in pH 10.5 culture and high alkalinity medium
showed remarkable effects towards the microalgae productivity. Two growth models,
Logistic and Gompertz tested in this study to determine the growth model for microalgae
in fabricated reactor. R2 values obtained for pH 8.5, 10.5 and 13.5 from both Logistic
and Gompertz are 0.9634, 0.9482, 0.7225 and 0.9626, 0.9474, 0.7249 respectively. This
shows that this microalgae best-fitted with Logistic model and growth kinetics of
Halochlorella rubescens can be determined by using this model |
