Conclusions
This research aimed at enrichment, growth, and accumulation of
biopolymer storage compounds using a chemostat bioreactor operated at
different NLRs. Chlorella vulgaris, and Chlorella
sorokiniana, the enriched species of this study stored lipids over
starch under the continuous growth conditions. Hence, this method is a
high throughput screening to select the most suitable microalgae species
for lipids production. These findings can be used in large scale
microalgae cultivation. Future studies are required to optimize lipids
productivity by adjusting cultivation parameters like dilution rate, pH,
temperature and light intensity for simultaneous microalgae enrichment
and growth, lipid production and biological nutrient removal.
