A Review on Application and Future prospects of Algae in Pharmaceutical and Food industry

International Journal for Research in Applied Science & Engineering Technology (IJRASET), 2022

Algae are photosynthesis-producing organisms that can be found in freshwater, wastewater, and aquatic environments. In order to get around a number of high-tech barriers in the algae biomass sector, it is necessary to improve the various activities and research. Algae have the potential to supply novel chemicals and bioactive compounds for the biotechnology industry. The abundance of algal diversity must be utilized for various applications. Algal biomass is a source of energy (biofuels), fertilizer, pollution control, stabilization, nutrition, high-value molecules, and various bioactive metabolites that can be investigated for new drugs in terms of their applicability in local and global markets. Microalgae have been widely used for the production of biomass and biofuel. As a result, large-scale experimental setups have been built to produce a lot of biomass and biofuel. Food, cosmetics, pharmaceutical, and nutraceutical industries all benefit greatly from microalgae. They also produce numerous biomolecules with added value, such as polyunsaturated fatty acids, beta-1,3-glucan, astaxanthin, lutein, phycobiliprotein beta-carotene, and chlorophyll, in addition to the previously mentioned application. The pharmaceutical, cosmetic, food and feed, and nutraceutical industries all use these biomolecules extensively commercially. Furthermore, this review focuses specifically on the broad application potential algae based nonenergy applications, such as pharmaceuticals, food ingredients, pigments and cosmetics by marine algae.

A Review on Marine Algae and Its Applications

Asian Journal of Pharmaceutical and Clinical Research

The ocean is the major essential source of structurally unique natural products that are mainly present in living organisms. The essential products extracted from marine microbes and marine algae are highly analyzed areas in instinctive product research. Marine algae are the novel food with potential nutritional values used for multiple purposes in industry and medicine. They show pharmacological activities which are helpful for the invention of bioactive compounds. Furthermore, marine algae have shown to provide an abundant source of natural bioactive compounds with antidiabetic, anti-inflammatory, antiviral, antifungal, hypolipidemic, antioxidant, anti-hypercholesterolemia, antibacterial, and antineoplastic properties. They produce new secondary metabolites that possess biological activities and have the potential to be developed as therapeutic agents. Macroalgal lectins, fucoidans, kainoids, and other substances have been routinely used in the research of biomedical and also have...

Algal extracts: Technology and advances

Engineering in Life Sciences, 2014

A number of studies on the development of a variety of extraction techniques to produce algal extracts have been reported. At present, attention is paid to the production of algal extracts without resorting to toxic organic solvents or aggressive extraction conditions that could deteriorate biologically active compounds found in algal cells. In this review, we present a critical overview of novel techniques to extract biologically active compounds from algae without their degradation. We compare the advantages and disadvantages of classic and novel extraction techniques such as supercritical fluid extraction, microwave‐assisted extraction, ultrasound‐assisted extraction, enzyme‐assisted extraction, pressurized liquid extraction. Additionally, we review the different biomass pretreatment methods. Products derived from algae are safe to plants, animals, and human. Therefore, they can be used in modern agriculture (biostimulants, bioregulators, feed additives) and in food, cosmetic, an...

Marine Algae: a Source of Biomass for Biotechnological Applications

Methods in molecular biology, 2015

2019

The global economic impact of the five leading chronic diseases — cancer, diabetes, mental illness, CVD, and respiratory disease — could reach $47 trillion over the next 20 years, according to a study by the World Economic Forum (WEF). According to the WHO, 80% of the world's population primarily those of developing countries rely on plant-derived medicines for healthcare. The purported efficacies of seaweed derived phytochemicals is showing great potential in obesity, T2DM, metabolic syndrome, CVD, IBD, sexual dysfunction and some cancers. Therefore, WHO, UN-FAO, UNICEF and governments have shown a growing interest in these unconventional foods with health-promoting effects. Edible marine macro-algae (seaweed) are of interest because of their value in nutrition and medicine. Seaweeds contain several bioactive substances like polysaccharides, proteins, lipids, polyphenols, and pigments, all of which may have beneficial health properties. People consume seaweed as food in various...

Challenges and Opportunities in the Present Era of Marine Algal Applications

2016

Marine algae are of high importance in their natural habitats and even more now in the world of green technology. The sprouting interest of the scientific community and industries in these organisms is driven by the fast-growing world of modern biotech‐ nology. Genomics, transcriptomics, proteomics, metabolomics and their integration collectively termed here as ‘marine algal-omics’ have broadened the research horizon in view of enhancing human’s life by addressing environmental problems and encouraging novelty in the field of pharmaceuticals among so many more. Their use in the human society dates back to 500 B. C. in China and later across the globe; they are still being used for similar purposes and more today. There is a hiking interest in marine algae and their derivatives—from phycoremediation, food supplements, pharmaceut‐ icals to dyes. Marine algae are currently considered as an emerging panacea for the society. They are being studied in a multitude of arenas. The multi-use ...

ALGAE AS NUTRITION, MEDICINE AND COSMETIC: THE FORGOTTEN HISTORY, PRESENT STATUS AND FUTURE TRENDS

Marine algae have been known and utilized from the ancient era. It is the source of chemical compounds mainly useful as a food for their richness in protein, fatty acids, minerals and vitamins. Physiologically active compounds also have a great potential to play an important role as cosmetic, medicine and as a pharmaceutical aid. In this review, the provided information will play an important role in the medicinal and cosmeceutical production in future.
