“…Infected fish showed darkened skin, inflammation, and cachexia, symptoms which were relieved following the co-treatment with L. plantarum and SH. Similar findings were obtained from studies conducted on the prebiotic potential of E. cava in E. tarda -infected zebrafish and olive flounder Vidhya Hindu et al, 2018), indicating that the incorporation of seaweed in fish feed results in improved growth and decreased mortality of infected fish. Histological studies showed that co-treatment with L. plantarum and SH improved goblet cell density in infected fish.…”

Sargassum horneri as a Prebiotic Dietary Supplement for Immunity Development in Streptococcus parauberis Infected Zebrafish Model

Sargassum horneri (SH) is a brown macroalgal species commonly found along the coast of Japan, China, and Korea. SH possesses valuable bioactive compounds that can be developed as functional food ingredients as well as pharmaceutical agents for both humans and animals. In this study, SH was tested for its potential prebiotic effect. Several solvent-assisted extracts of SH were tested on the growth of three species of probiotics (LAB) (Lactobacillus plantarum, Lactobacillus pentosus, Lactobacillus brevis) and fish pathogen bacteria (Streptococcus iniae, Streptococcus parauberis, Edwersiella tarda) both in vitro and in vivo. According to the in vitro results, Celluclast extract (SHC) and crude polysaccharide extract (SHCPs) of SH showed outstanding growth enhancing activity in all LAB species and excellent antibacterial activity against pathogenic bacteria dose-dependently. Both SHC and SHCPs induced the production of secondary metabolites from LAB. The secondary metabolites successfully reduced pathogenic bacterial growth. Furthermore, in vivo experiments revealed that co-treatment with LAB and SHC/SHCPs diminished the mortality of Streptococcus parauberis infected zebrafish by modulating iNOS, COX-2 expressions. Similarly, SH act as an anti-inflammatory agent against S. parauberis infection by hindering NF-κB pathway activation. Conclusively, the results achieved from the study suggest that S. horneri has the potential to be used as a prebiotic dietary supplement and possesses a protective effect against S. parauberis infections in the aquaculture industry.

“…However, research recently intensified on the crucial utilization of seaweeds and polysaccharides derived from algae as therapeutic agents to control diseases caused by Vibrio spp. and other bacteria in shrimp or other animals [52,53]. For example, the polysaccharide extracts from C. racemosa showed antibacterial activity against E. coli, Streptococcus aureus, and Salmonella sp., the extracts of Enteromorpha linza inhibited E. coli, S. typhimurium, and a polysaccharide extracted from Chaetomorpha aerea was active against B. subtilis, Micrococcus luteus, and S. aureus [54].…”

Antibacterial and Antiviral Activities of Local Thai Green Macroalgae Crude Extracts in Pacific White Shrimp (Litopenaeus vannamei)

Macroalgae are potentially excellent sources of bioactive secondary metabolites useful for the development of new functional ingredients. This study was conducted to determine the antimicrobial efficacy of the hot water crude extracts (HWCEs) of three species of local Thai green macroalgae Ulva intestinalis (Ui), U. rigida (Ur), and Caulopa lentillifera (Cl) and a commercial ulvan from U. armoricana (Ua). Chemical analysis indicated that the HWCE of Ur showed the highest sulfate content (13.9% ± 0.4%), while that of Ua contained the highest uronic acid and carbohydrate contents (41.47% ± 4.98% and 64.03% ± 2.75%, respectively), which were higher than those of Ur (32.75% ± 1.53% and 51.02% ± 3.72%). Structural analysis of these extracts by Fourier-transform infrared (FTIR) spectroscopy revealed that these HWCEs are complex with a signal at 1250 cm−1 corresponding to S=O stretching vibrations, while the signals at 850 cm−1 were attributed to the C–O–S bending vibration of the sulfate ester in the axial position. These HWCEs showed the growth suppression against some pathogenic Vibrio spp. Interestingly, the HWCEs from Ui at concentrations of 5 and 10 mg/mL completely inhibited white spot syndrome virus (WSSV) in shrimp injected with HWCE–WSSV preincubated solutions. This inhibitory effect was further confirmed by the reduction in viral loads and histopathology of surviving and moribund shrimp.

“…Polysaccharides are abundant carbohydrates in nature and comprise more than ten monosaccharide molecules conjoined by glycosidic bonds (Xie, Jin, et al, 2016). Seaweed‐derived polysaccharides as dietary supplements have widely been used in various aquatic animals for improving growth and immunity (Mohan, Ravichandran, Muralisankar, Uthayakumar, Chandirasekar, Seedevi, & Rajan, 2019; Vidhya Hindu et al, 2019). In recent years, the immunological functions of sulphated polysaccharides in terrestrial animals have been well‐understood, for which it has been considered the flashpoint in the area of polysaccharide research.…”

During the last decade, indiscriminate antibiotic use has increased with intensive aquaculture practice for disease management leading to the emergence. Hence, there is a need to devise sustainable feed additives with nutraceutical value. Marine macroalgae containing natural polysaccharides have drawn attention because of their significant bioactivities. Sulphated polysaccharide is a polysaccharide containing sulphate group in sugar unit, characterized as a potential bioactive component in fish feed. These are non‐digestible feed constituents and facilitate the host in multiple ways by rousing the growth and immune responses and developing a defence against harmful microorganisms and physical stressors. In aquaculture practice, marine macroalgae‐derived sulphated polysaccharides are considered prebiotic substances that regulate host organisms' growth and health status. This study overviews marine macroalgae‐derived sulphated polysaccharides' sources, structure, and modes of action in aquatic animals. Furthermore, the present review underscores the potential applications of marine macroalgae‐derived sulphated polysaccharides in aquaculture to improve the knowledge for additional headway in this field of research. Although the effects of sulphated polysaccharides in aquatic animals have been investigated, further exploration of the mechanisms of sulphated polysaccharides on the health status of aquatic animals is required, which may open a new window during sustainable disease and growth management in the aquaculture industry.
