Spirulina is an excellent source of proteins (Colla et al. 2007), pigments (RangelYaguiCde et al. 2004), poly unsaturated fatty acids (Sajilata et al. 2008) vitamins,
and phenolics (Ogbonda et al. 2007).
7.2.5 Microalgae and Cosmetics
The cosmetic products from microalgae include mostly hair care and sunscreen
products. Some typical microalgal species are well established in the skin care
market such as Mastocarpus stellatus, Chondrus crispus, Chlorella vulgaris,
Ascophyllum nodosum, Dunaliella salina, Spirulina platensis, Nannochloropsis
oculata, Alaria esculenta, etc. (Priyadarshani and Biswajit 2012; Stolz and
Obermayer 2005). The whole range of microalgal extracts can be largely found in
skin and face care products (e.g., refreshing or re-generant care products, anti-aging
cream, emollient, and as an anti-irritant in peelers (Stolz and Obermayer 2005).
Some microalgal species are grossly utilized in companies in the skin care market.
Some companies such as LVMH and Daniel Jouvance have landed in their personal
microalgal cultivation systems. The various extracts from these species are an
integral part of several cosmetics such as rejuvenating care products, anti-aging
cream, sunscreen lotions, and hair care products (Sharma and Sharma 2017;
Spolaore et al. 2006). There has been a soaring rise in procurement of various
sunscreen products (which includes extracts from different species of microalgae)
mainly due to increased public perception regarding skin cancer and photo-aging
processes (Spolaore et al. 2006).
7.2.6 Microalgae and Food Colorant
Microalgal stains have marketable applications as aesthetic/cosmetic constituents
and natural food colorants (Priyadarshani and Biswajit 2012). Various species of
microalgae are known to produce an extensive array of colored pigments and
consequently they are an appealing repertoire of natural colorants. Some microalgae
cover substantial amounts of Carotene (besides β-carotene). β-carotene is used as a
food colorant (major purpose in providing the yellow color to margarine), as a food
additive to augment the color of fish flesh and eggs yolks, and to improve the wellbeing and productiveness/fertility of grain-fed cattle (Borowitzka and Borowitzka
1987).
7.2.7 As Bio-Fertilizers
Cyanobacteria (microalgae) have been known to play a cardinal role in maintenance
and upsurge of fertility of soil, consequently enhancing crop growth (especially
paddy), yield, and productivity as a natural bio-fertilizer (Song et al. 2005). From the
cultivation perspective cyanobacteria in paddy cultivation is directly associated with
