Unlabelled: Ba.ckground: Sunscreen formulations primarily offer protection against UV induced damages however nowadays it also maintains skin natural physiological conditions. Current global market is flooded with numerous sunscreen products which offer protection to skin against several UV induced damages. However most of these sunscreen formulations offers narrow spectrum protection against UV and also suffer from stability as well as toxicity related issues.
Methods: Present work aims to isolate mycosporine amino acid (Mgy) from green alga namely Ulva fasciata (U. fasciata) and study its sunscreen potential against widely used domestic marketed formulation. Stability evaluations were also performed for almost 90 days.
Results: Results demonstrated that the isolated compound, mycosporine glycine (Mgy) preserved physicochemical properties of the product and offered good stability for all formulations throughout the experimental period. Furthermore, Mgy loaded carbopol gel showed better sunscreen protection against marketed formulation in a concentration dependent manner. (7.709).
Conclusion: (6.806) Novel Myg loaded gel was proved to demonstrate several quality characteristics that may unlock new prospects for the production of more efficient, safe, and economic skin-care products.

Green seaweeds, which make up a major population of total seaweed worldwide, possess various therapeutic properties. The aim of the study directed at isolating a (1 → 4) linked sulfated rhamno xyloglucuronan, designated as UFP-2, from the edible green seaweed Ulva fasciata Delile, and to evaluate its efficacy in modulating immune responses and inhibiting SARS-CoV-2 (Delta variant) infection. Anti-inflammatory potential of UFP-2 was demonstrated through the regulation of key cytokines involved in inflammatory responses triggered by viral infections, including interferons (IFN-α/γ), interleukin (IL-1β/12/33), and tumor necrosis factor (TNF-α).

Collagen nanoparticles (collagen-NPs) possess numerous applications owing to their minimal immunogenicity, non-toxic nature, excellent biodegradability and biocompatibility. This study presents a novel sustainable technique for one-step green synthesis of hydrolyzed fish collagen-NPs (HFC-NPs) using a hot-water extract of Ulva fasciata biomass. HFC-NPs were characterized using TEM, FTIR, XRD, ζ-potential analyses, etc.

Macroalgae growth depends on biologically available nitrogen, such as ammonium and nitrate, making nitrogen the most common growth-limiting factor for macroalgae. However, the role of surface microorganisms in promoting nitrogen transformation and improving nitrogen utilization by macroalgae remains unclear. In this study, 228 bacterial strains were isolated from the surface of , and high-throughput sequencing revealed significant shifts in the composition of surface bacterial communities under different nitrogen concentrations.

Chitosan nanoparticles (CNPs) are promising biopolymeric nanoparticles with excellent physicochemical, antimicrobial, and biological properties. In this investigation, CNPs were produced using Ulva fasciata biomass extract as a reducing agent. The SEM micrograph revealed that the biosynthesized CNPs appeared to be spheres with a mean size of 32.
