Which algae can produce fucoxanthin?
Fucoxanthin is a major carotenoid in diatom and brown algae. It accounts for more than one-tenth of the total carotenoid production in nature [8] and serves as a light-harvesting pigment [6].
What is fucoxanthin pigment?
Fucoxanthin is a xanthophyll that contributes more than 10% of the estimated total production of carotenoids in nature. It is an accessory pigment found in the chloroplasts of many brown macroalgae, such as Fucus spp., and the golden-brown unicellular microalgae, the diatoms.
What is the role of fucoxanthin in photosynthetic organisms?
Fucoxanthin is a major carotenoid found in the chloroplasts of brown seaweeds and diatoms. It makes a complex with chlorophyll protein and plays an important role in light harvesting and photoprotection for effective light utilization and upregulation of photosynthesis.
Which two conditions yield the highest fucoxanthin concentration?
Consequently, optimal light conditions (blue LED light at a light intensity of 100 μmol/m2/s and an 18/6 light/darkness cycle) were predicted to produce a maximum fucoxanthin production of 1.9 mg/L/day and a fucoxanthin content of 24.5 mg/g in dry weight under the minimum energy demand of 0.055 kWh/L/day.
How is fucoxanthin produced?
Fucoxanthin is produced by both micro- and macroalgae and it functions as an antenna pigment carotenoid, coupled to the thylakoid membrane, in the light-harvesting complexes and it transfers energy to the photosynthetic electron transport chain (Zarekarizi et al., 2018).
Does brown algae contain fucoxanthin?
Fucoxanthin is the main carotenoid produced in brown algae as a component of the light-harvesting complex for photosynthesis and photoprotection.
Does green algae contain fucoxanthin?
Fucoxanthin is found in brown seaweeds, diatoms and dinoflagellates and has a unique structure, including an allenic bond, an epoxide and a conjugated carbonyl group in the polyene chain of the molecule (Figure 1), which distinguishes its structure from that of plant carotenoids, such as β-carotene and lutein.
Is fucoxanthin water soluble?
Physical and Chemical Properties It is insoluble in water but soluble in organic solvents such as ethanol; it is typically lipid-soluble powder or oil.

What is fucoxanthin in microalgae?
Fucoxanthin is an important pigment and one of the main carotenoids in the chloroplasts of Phaeophyta (macroalgae) and marine diatoms (microalgae), which absorbs light basically in the green-yellow region of the visible spectrum, peaking at 510–525 nm, giving them a brown or brownish-green color.
Can we produce high-value products from microalgae?
Several reviews have demonstrated the production of traditional high-value materials from microalgae (e.g., Chew et al., 2017, Levasseur et al., 2020 and references therein). However, and from a different perspective, this paper examines the feasibility of producing new, exciting unconventional high-value products from microalgae.
What are the different approaches to developing novel algal compounds?
There are three main possible approaches for novel algal compounds from: (1) recently isolated yet less known microalgae; (2) selectively stressed conditions; and (3) enzymatically adjusted compounds from conventional molecules. All these approaches can be combined in a specific manner.
