Specific growth rate, final biomass concentration and biomass
productivity of C. vulgaris cultivated under photoautotrophic and
mixotrophic conditions were compared and summarized in Table 2.
The highest specific growth rates of C. vulgaris were 0.43 and
0.47 day1 when microalgae were cultivated under mixotrophic
conditions using hydrolyzed CW powder solution, and a mixture
of glucose and galactose as organic carbon sources, respectively.
These values were almost 3.5 times higher than those obtained
when cells were grown in inorganic medium supplemented with
non-hydrolyzed CW powder solution, and under photoautotrophic
mode of nutrition.
