“…Marine halophilic bacterial EPS have been concerned due to their novel characteristics and good antioxidant activity. Priyanka et al [61] isolated a sulfated EPS mainly consisting of glucose and having a molecular weight of 269 kDa from the marine halophilic strain Labrenzia sp. PRIM-30.…”

Marine-derived antioxidant polysaccharides have aroused extensive attention because of their potential nutritional and therapeutic benefits. However, the comprehensive comparison of identified marine-derived antioxidant polysaccharides is still inaccessible, which would facilitate the discovery of more efficient antioxidants from marine organisms. Thus, this review summarizes the sources, chemical composition, structural characteristics, and antioxidant capacity of marine antioxidant polysaccharides, as well as their protective in vivo effects mediated by antioxidative stress reported in the last few years (2013–2019), and especially highlights the dominant role of marine algae as antioxidant polysaccharide source. In addition, the relationships between the chemical composition and structural characteristics of marine antioxidant polysaccharides with their antioxidant capacity were also discussed. The antioxidant activity was found to be determined by multiple factors, including molecular weight, monosaccharide composition, sulfate position and its degree.

“…In consistent with our findings, several studies have shown the non-toxic nature of EPSs on different cell line models. 46,49,50 Regarding the no cytotoxicity effect of the EPSs on normal cell line of MDCK, it seems they have biocompatibility features. The biocompatibility is one of the desirable properties of the natural polymers for use in the formulation of food products, medicines and cosmetics.…”

Purpose: Due to the potential industrial and therapeutic applications of the yeast exopolysaccharides (EPSs), there has been an increasing demand to assess these biopolymers with improved characteristics. This study aimed to characterize the EPSs from Rhodosporidium babjevae (ATCC 90942 and IBRC-M 30088) as well as to evaluate their possible antioxidant, emulsifying and antiproliferative activities. Methods: Rhodosporidium babjevae was cultured for 5 days and following isolation of supernatant, EPSs precipitated with adding of cold absolute ethanol and freeze-dried. The EPSs chemical structure was determined by FT-IR, SEM, HPLC-SEC and GC-MS. Additionally the solubility, water holding capacity and emulsifying activity of EPSs were evaluated. In vitro, antioxidant activity was investigated against DPPH, superoxide and hydroxyl radicals. Finally the EPSs consequence on the cell proliferation of human breast adenocarcinoma (MCF-7) and Madin-Darby canine kidney (MDCK) cell lines was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) test. Results: R. babjevae excreted 1.6±0.2 g/L of the EPSs. The EPSs had three fractions with molecular weights of 1.02 ×106 , 5×105 and 2×105 Da. Mannose and glucose were found as the main monosaccharides of the EPSs (84:16 mol%, respectively). The EPSs exhibited emulsifying activity on sun flower oil. The scavenging activities were found to be dose-dependent and higher than hyaluronic acid. Significant difference among the EPSs treatments on the proliferation of MCF-7 and MDCK cell lines was not observed (P>0.05). Conclusion: These results show the interesting potential of the EPSs from R. babjevae as biocompatible compounds for using in food and pharmaceutical fields.

“…The same organism was used by Raguénès et al [183], who described for the first time a new microorganism, affiliated to the Vibrio genus, named Vibrio diabolicus, as being able to produce an innovative exopolysaccharide. Priyanka et al [184] collected several marine organisms, and isolated three EPS-producing strains, i.e., Alteromonas sp. PRIM-21 from a marine seaweed, Nitratireductor sp.…”

The marine bioprospecting could be considered as a new phenomenon, and already potentially more promising than terrestrial one in terms of possible discovery of new compounds. The secondary metabolites produced by associated-bacteria are actually studied for their remarkable role in several fields, including agricultural, industrial, medical, and bioremediation strategies against different contaminants. The use of such renewable sources could be helpful in the streamlining of the patenting process for natural compounds of good quality, produced with lower energy costs and less impact on the environment. Anyway, more improvements in the research and application of bioactive compounds as alternative to the synthetic counterparts have to be carried out for the costs reduction and the large-scale production upgrading. The use of marine invertebrates could help to overcome these difficulties, as hotspots of microbial diversity and favorable matrix for the development of conditions stimulating the production of substances with special activities. This review will deal with the current accepted definitions and recent advances concerning: (i) the marine symbiotic relationships in which microorganisms and invertebrates are involved; (ii) the principal taxa of marine invertebrates that establish interactions with microorganisms, the biodiversity of these latter, and their role in the symbiosis; (iii) we address the state of current literature and knowledge about the bacterial associated communities specialized in biosurfactants (BSs) and extracellular polymeric substances (EPSs) production; and, (iv) their potential biotechnological applications reported still now.
