Seaweeds and seaweed extract (SWE) possess antimicrobial, anti-inflammatory, prebiotic, and growth-promoting properties. Extracts can be prepared in different ways including wet, spray-dried, and freeze-dried forms. The aim of this study was to determine if spray drying of laminarin and fucoidan derived from Laminaria digitata had an effect on the microbiological and cytokine profile of the gas...

This study investigated the effect of Sargassum angustifolium and Gracilaria pulvinata extracts on the growth performance, body composition, antioxidant status and gut microbiota of rainbow trout (Oncorhynchus mykiss) fry. For this purpose, 540 fry of rainbow trout (initial weight 0.23±0.04 g) were distributed in 12 fiberglass tanks. Fish were fed with experimental diets containing 500 mg kg-1 ...

Laboratory and field experiments were performed to assess the ecological roles of natural products produced by the Brazilian red seaweed Laurencia obtusa. Laboratory assays revealed that the natural concentration of the crude organic extract of L. obtusa significantly inhibited feeding by two herbivores: the crab Pachygrapsus transversus and the sea urchin Lytechinus variegatus. It was verified...

The abnormal accumulation of iron in the brain has previously been proposed to be responsible for the neurodegenerative diseases through the oxidative damage to neuronal cells. Therefore, it seems practically meaningful to search for novel active substances protecting neurons against the iron-induced oxidative neurotoxicity in vitro. For this purpose, the aqueous extract was prepared from a spo...

Effect of Seaweed Liquid Extract (SLE) of Caulerpa scalpelliformis on growth and biochemical constituents of Vigna mungo was studied. The lower concentration of SLE of C. scalpelliformis (25%) enhanced the percentage of germination, shoot length, root length and biochemical constituents viz., chlorophyll, carotenoid, amino acid, reducing sugar and total sugar contents and α-amylase and β-amylas...

Impact of brown seaweed, Padina pavonica (Linn.) chloroform, and benzene extracts were evaluated against an economically important cotton pest, Dysdercus cingulatus (Fab.) (Pyrrhocoridae). The result reveled that between the two solvents, benzene extracts of P. pavonica caused more nymphal mortality. It reduce D. cingulatus egg hatchability than chloroform extract. Benzene extract also reduced ...

The present study was carried out to evaluate the physiological effects of seaweed supplementation on blood glucose levels, lipid profile, and antioxidant enzyme activities in subjects with type 2 diabetes mellitus. Subjects were randomized into either a control group or a seaweed supplementation group. Pills with equal parts of dry powdered sea tangle and sea mustard were provided to the seawe...

Seaweed oligosaccharides have attracted attention in food, agricultural, and medical applications recently. Compared to red brown seaweeds, fewer studies focused on the biological activity of green seaweed’s oligosaccharides. This study aimed produce bioactive ulvan via enzymatic hydrolysis from seaweed Ulva lactuca. Ulvan, a water-soluble polysaccharide, was obtained by hot water extraction. T...

The important cash crop of Chilli’s (Capsicum annum L) production and yield is hampered by Chilli Leaf Curl Virus Disease (CLCVD) in Sri Lanka. To manage CLCVD several insecticides were promised against the vectors CLCV. Indiscriminate use created unwanted human health hazards. current trends plant pathology intend to boost immunity host increase resistance pathogens. Therefore, this study was ...
