The halotolerant algae Dunaliella salina produces high levels of carotenoids, antioxidants, and fatty acids, which are required for aquaculture feed. Growth media composed of commercial fertilizers and salts is an inexpensive, accessible alternative to current culturing methods. D. salina growth was quantified using cell counting and UV-vis spectrophotometry following growth over a range of salinities in commercial fertilizer. D. salina exhibited an optimum growth rate in 0.5M NaCl media with Miracle-gro, representing the valuable alternative of commercialized products for algal cultivation in aquaculture. Future work will analyze lipid content of D. salina grown in this condition.
