Microalgae have emerged as environment friendly alternative source of valuable
products for energy, pharmaceutical and cosmetic industries. These
microorganisms have been also studied in wastewater treatments due to its ability
to remove CO2, nitrogen, phosphorus, and toxic metals. In this work, cultivation of
microalgae Chlorella vulgaris was carried out in aquaculture wastewater in order to
reduce its contents of NO3 and PO4. In addition, different concentration of inorganic carbon sources (NaHCO3 and Na2CO3) and addition times were considered for
determining suitable conditions in microalgae culture to produce proteins. It was
found that highest protein content (45 % w/w) was achieved at 3.4 g/L of NaHCO3
and 19 h of addition time.
