“…In agreement with the current study, the crude extracts of the Gracilaria verrucosa, which contained carbohydrates or glycoproteins component, enhanced T cell immune responses [32]. However, in contrast to the results of the current study, other studies [33,34] reported the stimulatory effects of the dietary administration of Gracilaria seaweed on innate immune responses of different fish species. Furthermore, the hot-water extract of various Gracilaria species increased immune responses and resistance of the Macrobrachium rosenbergii and white shrimp to Vibrio infection [35,36].…”

INTRODUCTION Algae contain diverse photosynthetic organisms that grow in aquatic environments. According to their morphology and chemical composition, marine macroalgae or seaweeds are classified into green algae (Chlorophyta), brown algae (Phaeophyta), and red algae (Rhodophyta) [1]. They have various bioactive organic and inorganic components with beneficial applications, such as feeding and health protection of humans and animals [2, 3]. Due to the emergence of antibiotic-resistant strains of bacteria, the medicinal plants might play an alternative role in the treatment of infectious diseases. The biological and pharmacological evaluation of seaweeds has led to discovering several natural or semi-synthetic drugs in recent years [4]. In response to harsh environmental conditions, algae produce various secondary metabolites [3, 5] that have bactericidal effects against some of the Grampositive and Gram-negative bacteria [6]. In addition, brown, red, and green seaweed extracts have been reported to have antioxidant, antiviral [7], antifungal [8], cytotoxic [9], and larvicidal properties [10]. The anti-inflammatory compounds of the seaweeds can be also used for medicinal applications [11]. The Gracilaria species grow in the tropical regions throughout the world. These Algae produce sulfated polysaccharides. The polysaccharide backbone of

“…Saponins and tannins were found to be absent (table 1). Some earlier studies have revealed that seaweed is an excellent source for bioactive molecules like sterols, carotenoids, fatty acid, pigments, tannins, bromophenols, flavonoids, polysaccharides, and phenolic acids that were researched for different biological properties [29]. The seaweed-phyco-constituents such as phenols and flavonoids were earlier found to have inhibition capacity of free radicals like those of our present findings [30].…”

Diabetes mellitus is a common metabolic disorder characterized by hyperglycemia and is a major cause of blindness, kidney failure, heart attack, stroke and is also responsible for lower limb amputation. The purpose of the present study was to evaluate the antioxidant and enzyme inhibitory efficacy of silver nanoparticles synthesized from brown alga, Sargassum wightii. The synthesized silver nanoparticles revealed spherical morphology with the size range of 18.45–41.59 nm. The green synthesized sliver nanoparticles of S. wightii were characterized through UV-visible spectroscopy, Fourier transform infrared spectroscopy, x-ray diffraction, field emission scanning electron microscopy, energy dispersive x-ray spectroscopy, zeta potential and by dynamic light scattering method. Presently, the enzyme inhibitory property of S. wightii-aqueous extract and synthesized silver nanoparticles of S. wightii against amylase and glucosidase was found to be 252.8 and , and 284.18 and , respectively. Similar trend of antioxidant activity have been recorded. The presently synthesized silver nanoparticle through green approach is an eco-friendly and cost effective one and it could form an effective pharmacological agent.

“…The existence of chlorophyll groups are confirmed through the C-H stretching vibrations at 2976, 2928 and 2895 cm −1 [41]. The weak absorption bands observed between 2344 and 2365 cm −1 correspond to the C-O stretching which are the characteristic peaks of carboxylic group [42]. The absorption band centered at 1654 cm −1 is due to the C-O stretching and N-O asymmetric stretching of the ester group [43].…”

The exploitation of marine seaweed (Sargassum wightii) extract as a low-cost sensitizer for a ZnO photoanode based solar cell is reported. The UV-vis absorbance spectrum of the Sargassum wightii (S. wightii) extract has exhibited three absorption peaks at 412.5, 610 and 659.5 nm in visible region of the solar spectrum. The pigment analysis has confirmed the presence of photosynthetic pigments such as chlorophylls, carotenoids and fucoxanthin. The photovoltaic performance of the S. wightii extract as a sensitizer in ZnO photoanode based solar cell is examined under simulated solar light irradiation. The solar cell sensitized with the S. wightii extract has delivered a short-circuit photocurrent density (J sc ) of 203 μA cm −2 , opencircuit photo-voltage (V oc ) of 0.33 V, maximum peak power (P max ) of 31.02 μW, fill factor of 0.46 and an overall solar to electrical energy conversion efficiency (η) of 0.07%. The sustainability of the solar cell is demonstrated through stability study. The overall results of this study suggest that the exploration of vast marine seaweed pigment resources and their use as sensitizer in solar cell would be a low-cost and environment friendly alternative to the expensive ruthenium metal complexes.
