“…Wu et al [44] have also reported high biomass production in Dunaliella salina cultures in white light with light intensity of 98 μmol m -2 s -1 photon flux. Different colours of light did not support the growth of test organism up to the level of growth achieved in control cultures kept in white light (Fig 6A) as reported for other microalgae [33,65]. This is expected as white light has a range of radiations required for optimal photosynthesis.…”

“…Light quality, duration and intensity are important factors influencing photosynthesis and biomass yield of microalgae [33, 63, 64]. Incubation of cultures of test organism continuously in 60 μE light increased its growth by 2.58 folds (Fig 6).…”

“…Five light intensities such as 10, 20, 40 60 and 80 μE were chosen to study effect of intensity of light on growth and carotenoid production. The effect of quality of light on growth and carotenoid production was studied by illuminating the culture vessels wrapped with the cellophane papers of red, blue, green and yellow colours [33]. The source of light was adjusted in such a way that each culture received same light intensity.…”

Since carotenoids are important as natural colorants, antioxidants, neutraceutics and pharmaceutics, the aim of the present study was to find a new good source of these pigments. We hereby report a green microalga Asterarcys quadricellulare PUMCC 5.1.1 as a new and good producer of carotenoids. The organism produced 35±1.75 μg carotenoids mg −1 dry biomass during stationary phase in control cultures. The growth and carotenoids production by the test microalga were optimized by varying nutrient growth media, pH, nitrogen and phosphate source, salinity, light quality, intensity and duration. The optimized conditions for carotenoid production were: Bold basal (BB) medium with pH 8.5, containing with10 mM nitrate, 3.5 mM phosphate and 0.17 mM salinity and illuminated with blue light with 60 μmol m -2 s -1 photon flux light intensity. Cultivation of cultures in the above mentioned optimized conditions resulted in nearly 3.0 fold increase in carotenoid production compared to the control cultures grown in unmodified BB medium. Using HPTLC, four carotenoids have been identified as β-carotene, lutein, astaxanthin and canthaxanthin. Further, carotenoids were also separated and purified by flash chromatography and the amounts of purified carotenoids were determined by HPLC. The organism produced 47.0, 28.7, 15.5 and 14.0 μg β-carotene, lutein, astaxanthin and canthaxanthin mg −1 dry biomass, respectively, under optimized conditions. The amount of total carotenoids (118 μg mg -1 dry biomass) produced by Asterarcys quadricellulare PUMCC 5.1.1 under optimized culture conditions was significantly higher than control cultures. Thus, this microalgal strain is a promising candidate for carotenoid production at commercial level.

“…A continuous search for potential new strains for large-scale production of these pigments are still advancing as the current major strains are still limited to a few species, namely, Spirulina platensis, Haematococcus pluvialis and Chlorella sp. Singh et al [ 136 ] discovered Asterarcys quadricellulare PUMCC 5.1.1 strain, a green microalga with a promising characteristic for carotenoid production while Kaushal et al [ 137 ] reported a new cyanobacterium Nodularia sphaerocarpa PUPCCC 420.1 which produces phycobiliprotein and reckoned as a good candidate for production at commercial scale.…”

Microalgae are known as a rich source of bioactive compounds which exhibit different biological activities. Increased demand for sustainable biomass for production of important bioactive components with various potential especially therapeutic applications has resulted in noticeable interest in algae. Utilisation of microalgae in multiple scopes has been growing in various industries ranging from harnessing renewable energy to exploitation of high-value products. The focuses of this review are on production and the use of value-added components obtained from microalgae with current and potential application in the pharmaceutical, nutraceutical, cosmeceutical, energy and agri-food industries, as well as for bioremediation. Moreover, this work discusses the advantage, potential new beneficial strains, applications, limitations, research gaps and future prospect of microalgae in industry.
