“…Alternative uses of biomass to profit from the green tide events were proposed in previous studies, including animal food, fertilizers, biodiesel, pharmaceutical or nutraceutical products (Bolton et al, 2009;Vijayavel and Martinez, 2010;Wang et al, 2010;Maceiras et al, 2011). Ulva prolifera is mainly used as food or for medical purposes, because it is rich in polysaccharides, proteins, and essential mineral elements for human health, and also has low content of fats and cellulose (Cai et al, 2009).…”

Aim: To evaluate the suitability of marine lactic acid bacteria (LAB) as starter cultures for Sargassum sp. fermentation to enhance its antioxidant and anticoagulation activity. Methods and Results: LAB isolated from marine source were characterized for their ability to utilize seaweed as a sole carbon source and applied to Sargassum fermentation. Fermentation period was optimized by monitoring the fermented sample at regular interval for a period of 18 days. Results revealed that a fermentation period of 12 days was effective with maximum culture viability and other desirable characteristics such as pH, total titratable acidity, total and reducing sugars. Under optimum fermentation period, the sample fermented with P1-2CB-w1 (Enterococcus faecium) exhibited maximum anticoagulation activity and antioxidant activity. Conclusions: The study reveals a novel well-defined starter culture from marine origin intended for seaweed fermentation for recovery of bioactive molecules. Significance and Impact of the study: The study provides information for the enhancement of bioactive molecules in an eco-friendly manner and also paves a way towards the development of wide range of seaweed functional foods.

“…Recently, marine algae have attracted increasing attention as a new source for bioactive compounds in addition to their nutritional importance, since the potential medicinal effects of algal constituents against various diseases or physiological concerns, such as anti-allergy, anticancer, antihypotension, anti-inflammation, anti-obesity, antioxidation, and antithrombosis effects, have been revealed [ 1 , 2 ]. In the terms of antimicrobial agents, marine algae have been globally tested, and various potential candidates, such as algal lectins, bromo-diterpenes, halogenated furanones, phlorotannins, and sesquiterpenes, have been found [ 3 , 4 ].…”

Antimicrobial and Antibiofilm Activities of Sulfated Polysaccharides from Marine Algae against Dental Plaque Bacteria

et al. 2018

Dental plaque biofilms cause various dental diseases; therefore, inhibiting the growths of the dental plaque bacteria which produce biofilms can be a strategy for preventing dental disease. Certain sulfated polysaccharides from marine algae exert antimicrobial activities against human bacterial pathogens in addition to their physiological benefits. On the basis of these observations, the antimicrobial and antibiofilm activities of sulfated polysaccharides from different marine algae were evaluated against dental plaque bacteria. Among the sulfated polysaccharides, a fucoidan from Fucus vesiculosus showed notable antimicrobial activities against the selected dental plaque bacteria, including some foodborne pathogenic bacteria. The minimum inhibitory concentrations were of 125 to 1000 µg mL−1. Regarding the antibiofilm activity, the fucoidan at the concentrations of above 250 µg mL−1 completely suppressed the biofilm formations and planktonic cell growths of Streptococcus mutans and S. sobrinus. However, no eliminative effect on the completed biofilm was observed. The fucoidan consisted of almost fucose base polysaccharide containing approximately 14.0% sulfate content. The average molecular weight of the fucoidan was changed by heat treatment (121 °C for 15 min) and it affected the antimicrobial activity.
