“…They were assessed further for eligibility based on the defined criteria: (1) inclusion of studies, specifically fucoxanthin production of microalgae involving fucoxanthin content or both growth (biomass concentration) and fucoxanthin content under different culture conditions, and the (2) exclusion of studies involving environmental studies (studies utilised fucoxanthin to analyse the microalgae community in a particular habitat). Finally, 28 articles were included in the present systematic review [ 4 , 5 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ]. The information from these articles was extracted and is summarised in Table 1 .…”

“…The RL also improved the biomass concentration of P. tricornutum [ 30 ]. A combination of RL, BL and even GL was adopted to improve biomass concentration and fucoxanthin content of microalgae [ 12 , 37 ]. A 1.46-fold and 1.06-fold increase in biomass concentration and fucoxanthin content were observed using a combination of RL and BL compared to single RL [ 12 ].…”

“…A 1.46-fold and 1.06-fold increase in biomass concentration and fucoxanthin content were observed using a combination of RL and BL compared to single RL [ 12 ]. On the other hand, BL + RL + GL boosted the biomass concentration and fucoxanthin content by 1.52-fold and 1.03-fold, respectively, compared to single BL [ 37 ]. Thus, a combination of different appropriate light spectra is suggested to acquire the desired amount of biomass concentration and fucoxanthin content.…”

Fucoxanthin Production of Microalgae under Different Culture Factors: A Systematic Review

et al. 2022

Fucoxanthin is one of the light-harvesting pigments in brown microalgae, which is increasingly gaining attention due to its numerous health-promoting properties. Currently, the production of microalgal fucoxanthin is not yet feasible from an economic perspective. However, the cultivation of microalgae at favourable conditions holds great potential to increase the viability of this fucoxanthin source. Hence, this study aimed to review the fucoxanthin production of microalgae under different conditions systematically. A literature search was performed using the Web of Science, Scopus and PubMed databases. A total of 188 articles were downloaded and 28 articles were selected for the current review by two independent authors. Microalgae appeared to be a more reliable fucoxanthin source compared to macroalgae. Overall, a consensus fucoxanthin production condition was obtained and proposed: light intensity ranging from 10 to 100 µmol/m2/s could achieve a higher fucoxanthin content. However, the optimal light condition in producing fucoxanthin is species-specific. The current review serves as an antecedent by offering insights into the fucoxanthin-producing microalgae response to different culture factors via a systematic analysis. With the current findings and recommendations, the feasibility of producing fucoxanthin commercially could be enhanced and possibly achieve practical and sustainable fucoxanthin production.

“…It has also been proven that blue lights induced 26% and 17% higher fucoxanthin in the marine diatom Thalassiosira weissflogii than white and red lights, respectively [87]. Furthermore, Gao et al (2021) also observed similar results in Tisochrysis lutea by comparing blue-green light with red lights [88]. Apart from light sources, light intensity also has significant effects on fucoxanthin synthesis [84].…”

The Potential of Marine Microalgae for the Production of Food, Feed, and Fuel (3F)

et al. 2022

Whole-cell microalgae biomass and their specific metabolites are excellent sources of renewable and alternative feedstock for various products. In most cases, the content and quality of whole-cell biomass or specific microalgal metabolites could be produced by both fresh and marine microalgae strains. However, a large water footprint for freshwater microalgae strain is a big concern, especially if the biomass is intended for non-food applications. Therefore, if any marine microalgae could produce biomass of desired quality, it would have a competitive edge over freshwater microalgae. Apart from biofuels, recently, microalgal biomass has gained considerable attention as food ingredients for both humans and animals and feedstock for different bulk chemicals. In this regard, several technologies are being developed to utilize marine microalgae in the production of food, feed, and biofuels. Nevertheless, the production of suitable and cheap biomass feedstock using marine microalgae has faced several challenges associated with cultivation and downstream processing. This review will explore the potential pathways, associated challenges, and future directions of developing marine microalgae biomass-based food, feed, and fuels (3F).

Marine microalgae offer a sustainable alternative source for the human diet’s essential omega-3-fatty acids, including docosahexaenoic acid (DHA, C22:6) and eicosapentaenoic acid (EPA, C20:5). However, none of them can produce DHA and EPA in a nutritionally balanced ratio of 1:1. As shown recently, the phototrophic co-cultivation of the golden-brown microalgae Tisochrysis lutea (DHA producer) with the green microalgae Microchloropsis salina (EPA producer) can provide microalgae biomass with a balanced DHA-to-EPA ratio with increased productivity compared to monocultures. This study evaluates whether other golden-brown (Isochrysis galbana) and green microalgae (Nannochloropsis oceanica, Microchloropsis gaditana) can enable the phototrophic batch production of omega-3 fatty acids in a nutritionally balanced ratio in co-culture. All co-cultivations applying a physically dynamic climate simulation of a repeated sunny summer day in Australia in LED-illuminated flat-plate gas lift photobioreactors resulted in increased biomass concentrations compared to their respective monocultures, achieving balanced DHA-to-EPA ratios of almost 1:1. Using urea instead of nitrate as a nitrogen source increased the EPA content by up to 80% in all co-cultures. Light spectra measurements on the light-adverted side of the photobioreactor showed that increased biomass concentrations in co-cultures could have been related to enhanced light use due to the utilization of different wavelengths of the two microalgae strains, especially with the use of green light (500–580 nm) primarily by golden-brown microalgae (I. galbana) and orange light (600–620 nm) predominantly used by green microalgae (N. oceanica). Phototrophic co-cultivation processes thus promise higher areal biomass yields if microalgae are combined with complimentary light-harvesting features.
