Abstract

From the past several years, algal biotechnology has gained noticeable interests among research-based organizations and industrial sectors. Recent studies have provided considerable evidence that microalgae-derived bioactive compounds could play a vital role in bio- and non-bio sectors of the modern world. Microalgae-based industrial exploitability ranges from basic biomass-based food and feeds nutraceuticals to high-value pharmaceuticals, cosmeceuticals, ecological and biomedical applications. With ever increasing scientific knowledge, social and environmental awareness, bio-inspired synthesis of microalgae-based green products, and recent advancements in algal biotechnology will extend the utilization of microalgae into new areas. Microalgae offer high biodiversity with an enormous potential to produce structurally complex yet bioactive compounds which are either impossible or difficult to produce via synthetic routes. In this paper, a range of value-added bioactive compounds from microalgae with industrial potentialities has been reviewed. The contribution ended with a critical description of the main research gaps and envisioned with future considerations to progress further in this exciting era of research.

Biosorption: An Interplay between Marine Algae and Potentially Toxic Elements—A Review

“…However, algae are heterogeneous from an evolutionary point of view [ 39 ]. Coastal area algae are mostly macroalgae and classified into three types: Chlorophyred (green), Rhodophyceae (red), and Phaeophycea (brown) algae [ 34 , 35 , 37 , 40 , 41 ]. Microalgae are found as phytoplankton throughout the oceanic ecosystem [ 40 ].…”

“…marine algae, offer several advantages such as (1) diverse multifunctional groups on their surface, (2) relatively small and uniform distribution of binding sites on the surface, (3) requires minimal preparatory steps, (4) no or less consumption of harsh chemicals, (5) naturally renewable, recyclable, and easily available all year round, (6) excellent retention capacity, and so on. Based on the literature, the utilization of marine algae as biosorbents has been successfully tested for several biotechnological and industrial applications including the removal of various potentially toxic elements [ 15 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ].…”

Marine Microalgae for Potential Lutein Production

“…The traditional knowledge of microalgae use by these indigenous people has now disseminated throughout the world population through migration. Further, growth in microalgal consumption has been due to the significant amount of research on the health and nutritional benefits of microalgae and these health benefits are especially relevant for our modern-day lifestyle [8]. As a result, presently, several microalgae are commercially cultivated for various nutraceutical products that are available in the market.…”

Analysis of Scientific Research Driving Microalgae Market Opportunities in Europe

“…Nutraceuticals can be defined as food nutrients that not only supplement the diet but also facilitate the prevention or treatment of diseases and disorders, according to the producers' claims. Recent papers have reviewed the state of the art about the biotechnological production and use of microalgae [87,88], with a particular focus on their use for food and feed [89][90][91] or nutraceuticals [92][93][94][95]. In Europe, the two main countries publishing in the nutraceuticals field were Italy and Spain with 29 and 26 publications, respectively (Figure 10d).…”
