Chlorella vulgaris is known to date back more than 2.5 billion years. C. vulgaris is a unicellular green algae that is eukaryotic (Wells). Because of its long life on earth it has been essential for C. vulgaris to evolve so it can survive. One feature that C. vulgaris has is its ability to grow rapidly. Because of its rapid growth scientist have been studying it and found that it can be used in many different ways; wastewater treatments, production of protein-rich food and feed additives, and biofuel (Cakmak,Wells). Specialty oils, and cosmetics can also be products from algae (Griffiths et al). The limit of fossil fuels makes it more important to be able to find renewable energy resources. There are many positives that come from using microalgae as a renewable resource; it has a large lipid content, make …show more content…
There is also a negative that is associated with C. vulgaris and that is the cost of production with low lipid productivity (Wells, Li). Scientist have been searching for the answer to have the largest lipid concentration from C. vulgaris. C. vulgaris can grown in a nutrient rich media that often contains, NaNO3, CaCl2, MgSO4, K2HPO4, KH2PO4, and NaCl. Scientist have been varying this components to be able to determine the best media that C. vulgaris can be grown in. A common one that has been done is the effects of nitrogen sources on cell growth and lipid concentration. Nitrogen limitations enhance lipid concentration but effects the growth rate, lipid content and overall lipid productivity, these are specific to certain species (Griffith et al). In a study that was conducted by Li et al., their results
