“…To grow microalgae in any large area of land, herbicides, pesticide and a maximum amount of water do not require, while it can be grown in wastewater such as domestic wastewater, industrial wastewater, palm oil milling e uents, or sewage wastewater and aquaculture wastewater (Tan et al, 2020b). The required media for all algal or microalgal species is different such as freshwater green algae and blue-green algae are required BG-11 media to grow, for marine algae and diatoms F/2 media is required while eukaryotic green algae and cyanobacteria required ASN-III and Walne media (Aishvarya et al, 2015).…”

Microalgae have higher nutritional value as they are abundant in protein, carbohydrates, lipids, and vitamins. Hence, they play several important roles in aquaculture and are known as a major source of the food chain for aquaculture organisms. Furthermore, they are also used indirectly or directly by humans as food supplements and medicines to improve health by strengthening the immune system. Microalgae are used as biocontrol agents because they have biocidal properties, produce biomolecules (beta carotene, PUFA, and astaxanthin), wastewater, are a renewable resource of biofuel, and are used in wastewater treatment. Due to the overexploitation of wild fish and pollution, aquaculture faces serious issues. Eco- friendly methods are required to overcome this problem, so, microalgae are in practicing, that control the water pollution. Fishmeal is a rich source of protein in aquaculture but it is decreasing over time and has become cost-effective, so, to solve the problem, microalgae are used to replace the fishmeal which (microalgae as aquafeed) is cheap and not required large area to grow. Microalgae are seemed to be very useful in the growth enhancement of aquatic organisms.

“…Chlorophyll b transfers the absorbed light energy to chlorophyll a for primary photochemistry (Govindjee & Braun, 1974) and the maximum absorption peaks are approximately 435 nm (blue light) and 645 nm (red light) (Wetzel, 2001), whereas chlorophyll c (accessory pigment) has maximum absorption bands at 630–635 nm (red light), 583–586 nm (yellow light) and 444–452 nm (blue light) (Meeks, 1974). Along with chlorophylls, carotenoids are synthesized and accumulated in the chloroplasts (Ashvarya, Jena, Pradhan, Panda, & Sukla, 2015). In some algae such as cyanobacteria and rhodophyta, phycobilins (water‐soluble pigment) are also found in the chloroplast.…”

Microalgae have a diverse application in food, pharmaceutical, beauty, animal feed and bioenergy industry. The demand for high‐quality pure microalgae biomass has steered the large‐scale production of microalgae in the photobioreactor. The usage of light‐emitting diodes (LEDs) as a light source is gaining attention as to conventional fluorescent lamps due to the higher energy conversion ratio, lower heat dissipation and its flexible application in photobioreactors. Besides, the narrow spectrum of LEDs could efficiently promote specific compounds in microalgae. This article reviews the influence of using various LED spectra on the biomass and lipid composition of microalgae. In addition, suggestions on the use of different LEDs cultivating common microalgae species in aquaculture are provided.

“…Typically, the medium should provide all the components required for the microalgae growth and maintenance to obtain high productivity. In addition, factors such as temperature, pH, and light intensity during the cultivation can affect the growth and development of microalgae biomass directly (Aishvarya et al, 2015).…”

During my seven years of study at Iowa State University, I met, worked, and interacted with many people. They helped me with my research, provided support, guidance, friendship, and inspiration when things got tough. I would like to express my sincere thanks and appreciation to all those people.First, I would like to express my sincere gratitude to my advisor and mentor, Dr. Zhiyou Wen, for offering me an opportunity to pursue the Ph.D. degree and for continuous supports of my research in the past four years. I am grateful for his patience, wisdom, enthusiasm, suggestions, and for motivating me farther than I thought I could go.Then, I would like to thank my committee members, Dr.
