Abstract:
The cellular biochemical composition of the isolated microalga Chlorella sp. was investigated in both favorable and nitrogen-depleted circumstances, with a particular focus on lipid classes and fatty acid distribution. When algal cells were grown in nitrogen-starvation media, the lipid and carbohydrate content increased, but the protein content decreased. Under control conditions, glycolipids were the most abundant lipid component at about 58.2% of total lipids, however under nitrogen stress conditions, neutral lipids became more prevalent at 74.8% of total lipids. The level of TAGs in nitrogen stressed cells was more than four times greater than in control cells. Oleic acid was the most prevalent fatty acid (47.2%) in the neutral lipids fraction. Under nitrogen stress, lipid quality analysis revealed that this alga has the potential to be used as a biodiesel feedstock.
