“…Phytochemicals show potential for use in healthcare due to their remarkable biological activity. However, the nutritional and chemical composition of seaweeds can vary based on factors such as species, geographical origin, seasonal and environmental fluctuations, harvest time, water temperature and processing techniques [ 5 ]. These factors must be considered when evaluating the potential use of seaweeds as a source of beneficial phytochemicals.…”

Ulva rigida green macroalgae contain a variety of polysaccharides. A recent study investigated the optimum concentration and yield of polysaccharide extraction from oven-dried U. rigida biomass using a water-soluble polysaccharide extraction method that adhered to safety standards. This study utilised complete factorial experiments to examine the effects of varying factors on polysaccharide extraction. Results showed a positive correlation between increased levels of all factors and higher polysaccharide extraction yield. This study also found that the main factors and their interaction had a significant impact on the extracted polysaccharides from U. rigida. The highest polysaccharide content and yield were 9.5 mg/mL and 189 mg/g, respectively. Water-soluble polysaccharides demonstrated the presence of reducing sugar (8 mg/g), phenolics (0.69 mg/g) and flavonoids (1.42 mg/g) and exhibited antioxidant properties. Results revealed that freeze-dried polysaccharide powders were primarily composed of the monosaccharide rhamnose. Preliminary results on the effect of these powders on probiotics demonstrated that supplementation of polysaccharides from U. rigida promoted viable Lactobacillus rhamnosus ATCC 53103 growth during cultivation. This discovery has the potential to revolutionise the human food industry and promote the development of functional ingredients for novel and future food products, with numerous applications in the nutraceutical and pharmaceutical industries.

Investigating alternative protein sources for ruminants in tropical regions is crucial due to distinct climatic conditions and limited resources. Scientists, acknowledging the challenges, are exploring locally accessible alternatives to develop cost-effective and sustainable protein supplements for ruminant nutrition, emphasizing the importance of understanding the nutritional composition for advancing livestock husbandry sustainability. The aim of this research is to elucidate alternative local protein sources for ruminants in tropical areas and assess their effectiveness in promoting sustainable production and enhancing ruminant nutrition. Protein feed sources are essential for providing amino acids to animals and producing animal products such as meat, milk, and wool. Inadequate protein in animal feed may have a detrimental impact on rumen fermentation and animal output. Therefore, alternative protein sources have received increased attention in order to replace the main protein source. The alternative protein sources in this review were divided into five categories: agricultural biomass, fodder shrubs, biological protein and plant weeds, insect protein and agro-industry biomass. Furthermore, plant secondary compounds found in alternative protein sources might be used to modulate rumen fermentation and improve animal performance. By focusing on regional sources of protein, feed costs are reduced while availability is raised. Based on this analysis, it can be concluded that there are a number of alternative protein sources that might be used in place of primary protein sources and that they could support ruminant production in the face of several animal feed crises. However, the potential use of any protein source should be assessed in light of the country’s availability and animal production practices.

Driven by a surge in global interest in natural products, macroalgae or seaweed, has emerged as a prime source for nutraceuticals and pharmaceutical applications. Characterized by remarkable genetic diversity and a crucial role in marine ecosystems, these organisms offer not only substantial nutritional value in proteins, fibers, vitamins, and minerals, but also a diverse array of bioactive molecules with promising pharmaceutical properties. Furthermore, macroalgae produce approximately 80% of the oxygen in the atmosphere, highlighting their ecological significance. The unique combination of nutritional and bioactive attributes positions macroalgae as an ideal resource for food and medicine in various regions worldwide. This comprehensive review consolidates the latest advancements in the field, elucidating the potential applications of macroalgae in developing nutraceuticals and therapeutics. The review emphasizes the pivotal role of omics approaches in deepening our understanding of macroalgae’s physiological and molecular characteristics. By highlighting the importance of omics, this review also advocates for continued exploration and utilization of these extraordinary marine organisms in diverse domains, including drug discovery, functional foods, and other industrial applications. The multifaceted potential of macroalgae warrants further research and development to unlock their full benefits and contribute to advancing global health and sustainable industries.
