The review covers recent literature on the ocean as both a source of biotechnological tools and as a source of bio-inspired materials. The emphasis is on marine biomacromolecules namely hyaluronic acid, chitin and chitosan, peptides, collagen, enzymes, polysaccharides from algae, and secondary metabolites like mycosporines. Their specific biological, physicochemical and structural properties together with relevant applications in biocomposite materials have been included. Additionally, it refers to the marine organisms as source of inspiration for the design and development of sustainable and functional (bio)materials. Marine biological functions that mimic reef fish mucus, marine adhesives and structural colouration are explained.

“…), and are interesting for cosmetic and pharmaceutical use as active ingredients in cosmeceuticals (Rastogi et al. ). Rhodophyta are an ideal source for MAAs because they are known to accumulate the highest concentrations per dry weight and to contain the greatest variety among the different algal divisions, with shinorine, porphyra‐334, palythine, asterina‐330, mycosporine‐glycine, usujirene, palythinol and palythene being the most abundant representatives (Karsten et al.…”

“…They are among the strongest UV-absorbing natural products and their absorption maxima are stretched between 268 and 362 nm depending on their chemical structure. Therefore, MAAs increase the UV-absorbing capacity of respective organisms (Jansena et al 1998), and are interesting for cosmetic and pharmaceutical use as active ingredients in cosmeceuticals (Rastogi et al 2017).

Rhodophyta produce a variety of chemically different mycosporine‐like amino acids (MAAs), compounds that are known as some of the strongest ultraviolet (UV) absorbing molecules in nature. Accordingly, they primarily act as photoprotectants against harmful levels of solar ultraviolet radiation in the UV‐A and UV‐B range. In order to get a deeper understanding of the chemical diversity of MAAs in red algae, pure standards of eleven mycosporine‐like amino acids were isolated from three different species ( Agarophyton chilense , Pyropia plicata and Champia novae‐zelandiae ) using various chromatographic methods. Their structures were confirmed by nuclear magnetic resonance and mass spectrometry. Four out of the eleven MAAs are reported for the first time in algae. In addition, a new high‐performance liquid chromatography method was developed for the separation of all isolated MAAs and successfully applied for the analysis of twenty‐three red algal species of marine origin. All of them contained MAAs, the most abundant compounds were shinorine, palythine, asterina‐330 and porphyra‐334. For some samples, the direct assignment of MAAs based on their UV spectra was not possible; therefore, the target analytes were enriched by a simple concentration step, followed by liquid chromatography‐mass spectrometry analysis of the extracts. This approach enabled a deeper insight into the MAA pattern of red algae, indicating that not only the four dominant ones are synthesized but also many others, which were often described as unknown compounds in previous studies.

“…The yellow pigment of Thermus was proposed as a photoprotectant [ 99 ]. Carotenoids of archaea [ 100 ], yeasts [ 101 , 102 ], cyanobacteria, and algae [ 103 ] also function as photoprotectants. Marennine, a blue pigment produced by diatom Haslea is involved in greening on oysters [ 104 ], and displayed a prophylactic effect [ 105 , 106 ].…”

Microbial pigments play multiple roles in the ecosystem construction, survival, and fitness of all kinds of organisms. Considerably, microbial (bacteria, fungi, yeast, and microalgae) pigments offer a wide array of food, drug, colorants, dyes, and imaging applications. In contrast to the natural pigments from microbes, synthetic colorants are widely used due to high production, high intensity, and low cost. Nevertheless, natural pigments are gaining more demand over synthetic pigments as synthetic pigments have demonstrated side effects on human health. Therefore, research on microbial pigments needs to be extended, explored, and exploited to find potential industrial applications. In this review, the evolutionary aspects, the spatial significance of important pigments, biomedical applications, research gaps, and future perspectives are detailed briefly. The pathogenic nature of some pigmented bacteria is also detailed for awareness and safe handling. In addition, pigments from macro-organisms are also discussed in some sections for comparison with microbes.
