During the preliminary tests of four commercial microalgae strains,
it’s found that Scenedesmus dimorphus (UTEX 1237) and Neochloris
oleoabundans (UTEX 1185) were unable to grow on the swine
wastewater. So Chlorella vulgaris (UTEX 2714) and Chlamydomonas
reinhardtii (UTEX 90) were further investigated for the bioremediation
ability. Correlations between the optical density of C. vulgaris and
C. reinhardtii at 680 nm and the cell number were pre-determined.
These correlations are shown as the equations 5 and 6, which were
used to determine the growth kinetics of both species
