“…In vitro studies showed that glycerol galactoside of the red alga Pyropia yezoensis was resistant to action of saliva, pancreatic and digestive enzymes (Muraoka et al, 2008). Several algal polysaccharides are fermented by specific subsets of gut microbes; for example, agarose-derived neoagaro-oligosaccharides were fermented by beneficial gut bacteria Lactobacillus sp.…”

The aim of this study was to evaluate the effect of the inclusion of red seaweed supplementation to standard poultry diets on production performance, egg quality, intestinal histology, and cecal short-chain fatty acids in Lohmann Brown Classic laying hens. A total of 160 birds were randomly assigned to 8 treatment groups. Control hens were fed a basal layer diet; positive control hens were fed a diet containing 2% inulin; and 6 treatment groups were fed a diet containing one of the following; 0.5, 1, or 2% Chondrus crispus (CC0.5, CC1, and CC2, respectively) and one of the same 3 levels of Sarcodiotheca gaudichaudii (SG0.5, SG1, and SG2, respectively). Dietary supplementation had no significant effect on the feed intake, BW, egg production, fecal moisture content, and blood serum profile of the birds. The feed conversion ratio per gram of egg was significantly more efficient (P = 0.001) for CC2 and SG2 treatments. Moreover, SG1 supplementation increased egg yolk weight (P = 0.0035) and birds with CC1 supplementation had higher egg weight (P = 0.0006). The SG2 and CC2 groups had greater (P < 0.05) villus height and villus surface area compared with the control birds. Seaweed supplementation increased the abundance of beneficial bacteria [e.g., Bifidobacterium longum (4- to 14-fold), Streptococcus salivarius (4- to 15-fold)] and importantly reduced the prevalence of Clostridium perfringens in the gut of the chicken. Additionally, the concentrations of short-chain fatty acids, including acetic acid, propionic acid, n-butyric acid, and i-butyric acid, were significantly higher (P < 0.05) in CC and SG treatments than in the control. In conclusion, dietary supplementation using red seaweed inclusions can act as a potential prebiotic to improve performance, egg quality, and overall gut health in layer hens.

“…The resulting solution was freeze-dried. The residual colorless crystal was identified as glycerol galactoside (a mixture of floridoside, L-isofloridoside and D-isofloridoside, in proportions of 11, 62 and 27%, respectively) by nuclear magnetic resonance [10], and purity was assessed by HPLC ([95%) [9].…”

Glycerol galactoside (GG; floridoside: 2-O-glycerol-a-D-galactopyranoside, and isofloridoside: 1-O-glycerola-D-galactopyranoside) is known to be a component of edible red seaweed nori. Recently, we have found that lowquality nori (color-faded nori), which has a low protein content, contains a large quantity of GG. From further studies, we have also found that GG has prebiotic characteristics in vitro. In this study, we evaluated the in vivo prebiotic activity of GG in rats. Dietary GG selectively increased the cecal Bifidobacterium count in rats. Other indices of prebiotics, such as pH of cecal content, organic acid concentrations, and fecal weight, also supported the existence of prebiotic activity of GG. The present data will also contribute to the development of a new method of utilizing color-faded nori as a health-promoting foodstuff.

“…They improve the growth of beneficial bacteria in the environment of harmful microbiota. MAAs is unique components of red seaweeds and seaweed components are known as supportive reinforcement of the microbiota in intestinal diseases [17][18][19][20]. MAAs had been shown to regulate intestinal epithelial cell differentiation and cytokine (IL-1β, IL-6) production [21].…”

Gastrointestinal microbiota includes bacteria, archaea, viruses, fungi and other eukaryotes. The genus Bifidobacterium is considered the dominant once; it has an important role on immunologic, hormonal and metabolic homeostasis of the host. Recent studies demonstrated that the Mycosporin-like Amino Acids (MAAs) had prebiotic effects and they modulated host immunity by regulating the proliferation and differentiation of intestinal epithelial cells, macrophage and lymphocytes. Also MAAs modulate NF-κB and tryptophan metabolism. Modulation NF-κB and tryptophan metabolism induced a beneficial effect on central nervous cascade. The safety of Bifidobacterium species is known; although they do not produce MAAs, their presence is required for immunological response continuity of intestine. Thereby we hypothesize that if we could create Bifidobacteria species producing MAAs via genetic engineering; they might have stronger immuno-stimulatory properties and might be used as more potent pharmacological agents in neurological diseases secondary to impaired microbiota.
