economic importance of microalgae

2019). Peptides, including but not limited to those from cyanobacteria, tend to be toxic substances possessing strong cytotoxic activity. The microalga D. salina readily produces vitamins A and E, pyridoxine, nicotinic acid thiamine, riboflavin, and biotin [205]. Pathologic angiogenesis promotes tumors and helps them to grow [230] Therefore, angiogenesis is considered the cause of tumor growth and expansion in cancer. Thus, microalgae would realize an important role in aquaculture. Likewise, Phaeodactylum tricornutum shows high lipid and protein contents and contains both EPA and DHA. This novel approach uses new, powerful, rapidly evolving genetic engineering tools to identify and selectively modify the right genes. Most recently ocean cultivation system has attracted attention for commercial scale production of algae due the advantages like mixing of the culture by ocean waves, utilizing dissolve nutrients large area availability, etc. See water is also a good alternative for commercial cultivation of microalgae. Protective effect of fucoxanthin isolated from Sargassum siliquastrum on UV-B induced cell damage. Pulz O. Photobioreactors: production systems for phototrophic microorganisms. Furthermore, the presence of cellulose in algal cell walls requires efficient degradation and conversation, approaches that also need to be optimized. d Docosahexaenoic acid DHA produced by the engineered strain of diatom Phaeodactylum tricornutum. 3). -carotene has a crucial role in vision and the immune system, due to its relation to vitamin A. 2020), and the world population keeps on growing. Lobo V, Patil A, Phatak A, Chandra N. Free radicals, antioxidants and functional foods: impact on human health. Algae, both floating and attached forms, marine as well as fresh water, provide the primary food for fish and other aquatic animals. Algae form organic food molecules from carbon dioxide and water through the process of photosynthesis, in which they capture energy from sunlight.Similar to land plants, algae are at the base of the food chain, and, given that plants are virtually absent from the oceans, the existence of nearly all marine lifeincluding whales, seals, fishes, turtles . Bioresour Technol. Ranging in size from unicellular microalgae to giant kelp, these aquatic plants are characterized by their lack of flowers, formal roots, leaves, or even stems.

Elsevier Inc, pp 75145. The amount of lignocellulose also increases the cost of the whole pretreatment process. Algae played an important role in reclamation of toxic soil contaminated with coal mining (Mohlov, 2008), mercury (Mishra and Nanda, 1997), cadmium and lead (Souza et al., 2012). Microalgae are microscopic algae, typically found in freshwater and marine systems.

Bioethanol production from microlage is an excellent effort in the development of sustainable biofuels, still there are some challenges regarding large-scale production and commercialization of this clean biofuel. As a result, it has been found that fish currently only contributes around 15% of the global demand for EPA and DHA, and krill as an alternative source adds 0.3% (Salem and Eggersdorfer 2015).
