“…And it was consistent with the results of three microalgae. That may be different species of microalgae have different light-utilizing patterns, and the optimal light wavelength for microalgae varies from species to species [11]. And molecular mechanism may be that photons from different spectra can change the receptor protein, and trigger signal transduction cascade for the regulation of photosynthesis, photo orientation, developmental process, and the circadian clock [49].…”

“…Consequently, microalgae as a promising raw material for bioenergy production could meet the demand of the ever-increasing market for biofuel production. Light factors such as intensity and wavelength are essential parameter in photosynthesis for growth of microalgae [11].

Microalgae are a kind of promising raw material for bioenergy production and carbon sequestration. To enhance cell growth and production efficiency, great efforts were made for exploring the appropriate intensity and quality of light to improve the synthesis of the value-added products. The aggregation-induced emission (AIE) material (Astrazon Brilliant Red 4G), active for converting blue-green light to red light (630–680 nm), was for the first time applied in the research to achieve high fatty acid yield with considerable carbon-neutral ability. After 10 days-incubation, it revealed that AIE light-converting films boosted the biomass of microalgae Scenedesmus obliquus, Phaeodactylum tricornutum, and Chlamydomonas reinhardtii by 13.00%, 28.00%, and 26.00%, and the total lipid contents increased by 34.60%, 17.74%, and 22.63%, with the carbon sequestration capacity raised by 17.18%, 38.89%, and 35.71%. Furthermore, AIE light-converting films promoted the accumulation of unsaturated fatty acids (UFAs) in all three microalgae. Our study demonstrated the potential application of AIE light-converting films for cultivating microalgae to capture high carbon dioxide for photosynthesize carbon-neutral energy and high-valued active compounds.

“…The cultivation of Haematococcus to gain biomass or astaxanthin extract is possible under photoautotrophic, heterotrophic, and mixotrophic growth mode [ 8 , 47 , 48 ]. The recipe for the photoautotrophic mode of culture typically requires light, CO 2 , water, and nutrients [ 49 ]. Light is a source of energy, whereas inorganic compound mostly serves as a carbon/nitrogen source to produce algal biomass rich in lipids, protein, and sugars [ 50 ].…”

A Review on Haematococcus pluvialis Bioprocess Optimization of Green and Red Stage Culture Conditions for the Production of Natural Astaxanthin

As the most recognizable natural secondary carotenoid astaxanthin producer, the green microalga Haematococcus pluvialis cultivation is performed via a two-stage process. The first is dedicated to biomass accumulation under growth-favoring conditions (green stage), and the second stage is for astaxanthin evolution under various stress conditions (red stage). This mini-review discusses the further improvement made on astaxanthin production by providing an overview of recent works on H. pluvialis, including the valuable ideas for bioprocess optimization on cell growth, and the current stress-exerting strategies for astaxanthin pigment production. The effects of nutrient constituents, especially nitrogen and carbon sources, and illumination intensity are emphasized during the green stage. On the other hand, the significance of the nitrogen depletion strategy and other exogenous factors comprising salinity, illumination, and temperature are considered for the astaxanthin inducement during the red stage. In short, any factor that interferes with the cellular processes that limit the growth or photosynthesis in the green stage could trigger the encystment process and astaxanthin formation during the red stage. This review provides an insight regarding the parameters involved in bioprocess optimization for high-value astaxanthin biosynthesis from H. pluvialis.

“…In aquaculture, two important characteristics to evaluate the potential of microalgae species as feeds are their biochemical composition and the rate of biomass increase (De Castro Araújo & Garcia, 2005). The main biochemical constituents of diatoms are lipids, proteins, and carbohydrates, which are stored in their cells and are directly based on their biomass production (Kwan et al, 2021). Apart from the application as live feeds, a recent study showed the high potential of diatoms as aquaculture feed ingredients as an alternative to traditional fish meal ingredients (Nagappan et al, 2021).…”

Microalgae are very important organisms as primary producers and have a wide range of applications in areas such as aquaculture, pharmaceuticals, medicine, biofuels, and others. In this study, the effect of temperature and salinity on growth, biomass, proximate composition, and lipid production of Chaetoceros calcitrans (Paulsen) and Thalassiosira weissflogii (Grunow) were investigated. The best growth rate (SGR) and highest biomass production were observed at 30°C and 30 ppt for C. calcitrans and at 30°C and 25 ppt for T. weissflogii. At these optimum temperature and salinity combinations, the maximum cell density was accomplished by day 12 for C. calcitrans (6.74 × 106 cells ml˗1) and by day 10 for T. weissflogii (3.45 × 106 cells ml˗1). The proximate composition during this period was 38.25 ± 0.99% protein, 16.96 ± 0.90% lipid, and 9.39 ± 0.59% carbohydrate in C. calcitrans, compared to 13.49 ± 0.28% protein, 10.43% ± 0.25% lipid and 16.49 ± 0.47% carbohydrate in T. weissflogii. Furthermore, over 35% of lipids in C. calcitrans were palmitic acid (C16), while in T. weissflogii, over 24% of lipids were myristic acid (C14). Although C. calcitrans exhibited higher lipid content than T. weissflogii, both species displayed higher levels of saturated (SFA) and monounsaturated (MUFAs) fatty acids and low levels of polyunsaturated fatty acids (PUFAs). The findings illustrated that under their optimum temperature and salinity combinations, both species might produce significant sources of lipids, which can be utilised in various activities such as aquaculture, pharmaceuticals, medicine, biofuels and others.
