“…Yet, one major bottleneck in NP research is the limited accessibility to novel sources for exploration (Wright, 2019), which highlights the importance of retrieving novel marine microbes and exploring the extensive pool of underexplored assets that their metabolism encodes (Bull et al, 2005). Macroalgae, also referred to as seaweeds, represent a diverse group of ecological, biotechnological and industrially significant organisms that can be found in several marine habitats, from intertidal zones to deeper oceanic regions (Abdel‐Kareem & ElSaied, 2022; Ortega et al, 2019). They play a major role in nutrient cycling, oxygen production, carbon fixation and coastal protection, with many living beings relying on them as a primary food source, habitat and shelter, stressing their importance in maintaining marine systems health, resilience and biodiversity (Chan et al, 2006).…”

Actinomycetota, associated with macroalgae, remains one of the least explored marine niches. The secondary metabolism of Actinomycetota, the primary microbial source of compounds relevant to biotechnology, continues to drive research into the distribution, dynamics, and metabolome of these microorganisms. In this study, we employed a combination of traditional cultivation and metagenomic analysis to investigate the diversity of Actinomycetota in two native macroalgae species from the Portuguese coast. We obtained and taxonomically identified a collection of 380 strains, which were distributed across 12 orders, 15 families, and 25 genera affiliated with the Actinomycetia class, with Streptomyces making up approximately 60% of the composition. Metagenomic results revealed the presence of Actinomycetota in both Chondrus crispus and Codium tomentosum datasets, with relative abundances of 11% and 2%, respectively. This approach identified 12 orders, 16 families, and 17 genera affiliated with Actinomycetota, with minimal overlap with the cultivation results. Acidimicrobiales emerged as the dominant actinobacterial order in both macroalgae, although no strain affiliated with this taxonomic group was successfully isolated. Our findings suggest that macroalgae represent a hotspot for Actinomycetota. The synergistic use of both culture‐dependent and independent approaches proved beneficial, enabling the identification and recovery of not only abundant but also rare taxonomic members.

“…are regarded as biological resources with a high level of potential as a functional ingredient in the food processing worldwide and used for a variety of value-added food products [12]. Furthermore, some chemicals and pharmaceuticals are extracted from seaweeds and incorporated into products because of the availability of these bioactive compounds and their capacity to generate secondary metabolites that exhibit potential antimicrobial, antiviral, anti-inflammatory, anti-ulcer, and anticancer properties [13].…”

In response to customer demand for a balanced and healthful diet, there is a growing trend in manufacturing innovative dairy products enhanced with plant ingredients with particular pharmacological qualities. Yoghurt is a dairy product that is becoming increasingly popular among consumers since it is a great way to absorb functional food elements like probiotics, prebiotics, and antioxidants. It’s critical to increase public awareness of the health hazards associated with yoghurt use in addition to adding affordable, nutrient-dense functional additives to Yoghurt. Due to their high nutritional content and potential health benefits, algae have long been utilized as a food source. However, rising interest is in using them as enrichment components in manufacturing new foods. Consequently, this paper draws attention to the potential of Seaweed in manufacturing yoghurt, as shown in current scientific literature. However, more research needs to be done on adding seaweed components to Yoghurt, which is considered safe for human ingestion and has undergone clinical testing. We hope this study will raise awareness about the need for more research to address the growing demand for Yoghurt.

The Red Sea coastline is known for its diverse range of seaweeds, which have been hypothesized to possess therapeutic attributes. The primary aim of this research was to evaluate the antifungal and anti-inflammatory characteristics of the ethanol crude extract obtained from two types of algae, namely Padina pavonica (P. pavonica) and Laurencia catarinensis (L. catarinensis) from the Red Sea. It was revealed from FTIR analysis of P. pavonica and L. catarinensis ethanolic extracts that the strong band at 3366 cm−1 and 3339 cm−1 corresponds to alcoholic O-H stretching in both extracts. GC-MS phytoconstituent profile of the extract was dominant with a wide range of chemical classes mainly steroids, terpenes, fatty acids, fatty acid esters, retinoid derivatives, alcohols, carotenoids and alkanes. The results of the antifungal activity assay indicate that P. pavonica had the strongest activity against Aspergillus fumigatus, with a mean value of 23.50 ± 0.55 mm. Similarly, L. catarinensis demonstrated significant antifungal activity against Candida albicans, with a mean value of 21.00 ± 2.64 mm. The hemolysis exhibited a positive correlation with the dosage of extracts, with an observed increase in hemolysis as the dosage increased. Besides the antiinflammatory activity of the algal extracts induced by carrageenan demonstrating a dose-dependent relationship between the inhibition of paw edema and the dosage of the extract.
