“…Among the algal phyla or classes, Chlorophyta (green), Phaeophyceae (brown) and Rhodophyta (red), the red seaweeds phyla contain the largest number of species [ 23 ]. Hereby, it is highlighted the nutraceutical potential that this phylum/class represents [ 39 ]. Seaweeds have been seen as a feedstock for bioactive molecules that can be incorporated in the daily diet as a supplement in order to promote human health, thus being considered nutraceutical food products [ 40 ].…”

Chondracanthus teedei var. lusitanicus: The Nutraceutical Potential of an Unexploited Marine Resource

Presently, there is a high demand for nutritionally enhanced foods, so it is a current challenge to look at new raw food sources that can supplement beneficially the human diet. The nutritional profile and key secondary metabolites of red seaweeds (Rhodophyta) are gaining interest because of this challenge. In this context, the possible use of the red seaweed Chondracanthus teedei var. lusitanicus (Gigartinales) as a novel nutraceutical source was investigated. As a result, we highlight the high mineral content of this seaweed, representing 29.35 g 100 g−1 of its dry weight (DW). Despite the low levels of calcium and phosphorus (0.26 and 0.20 g 100 g−1 DW, respectively), this seaweed is an interesting source of nitrogen and potassium (2.13 and 2.29 g−1 DW, accordingly). Furthermore, the high content of carbohydrates (56.03 g 100 g−1 DW), which acts as dietary fibers, confers a low caloric content of this raw food source. Thus, this study demonstrates that C. teedei var. lusitanicus is in fact an unexploited potential resource with the capability to provide key minerals to the human diet with promising nutraceutical properties.

Gracilaria sp. merupakan salah satu jenis rumput laut yang diproduksi secara luas dengan hasil melimpah dan kurang termanfaatkan dengan baik. Yoghurt menjadi salah satu produk pangan hasil fermentasi bakteri Lactobacillus plantarum dan Streptococcus thermophilus, namun dewasa ini banyak pengembangan terkait yoghurt dengan kombinasi beberapa bahan selain sumber nabati. Penelitian ini bertujuan untuk menentukan pengaruh penambahan Gracilaria sp. terhadap karakteristik yoghurt Gracilaria sp. hasil fermentasi bakteri L. plantarum dan S. thermophilus. Metode penelitian yang digunakan yaitu rancangan acak lengkap (RAL) dengan penambahan Gracilaria sp. 30%, 40%, dan 50%. Hasil penelitian menunjukkan bahwa konsentrasi penambahan Gracilaria sp. yang berbeda pada pembuatan yoghurt memengaruhi parameter kadar protein, kadar lemak, total asam, nilai pH, total BAL dan organoleptik. Konsentrasi penambahan Gracilaria sp. terbaik pada yoghurt hasil fermentasi L. plantarum dan S. thermophilus yaitu konsentrasi 30%, karena memiliki nilai total bakteri asam laktat sebesar 6,29 Log (cfu/mL) dan hasil uji organoleptik lebih disukai konsumen selang kepercayaan sebesar 6,50<µ<6,55.

“…The genus Gracilaria, is found in intertidal and subtidal zones of Indo-Pacific and Western Atlantic parts of earth. It is the largest genus in Gracilariales, and belongs to the Gracilariaceae family (Torres et al, 2019). The genus Gracilaria has been investigated for its nutritional, and biochemical potentials and valuable polysaccharide agar with a fast growth rate, ease of vegetative reproduction and other attributes favouring its cultivation (Porse and Rudolph, 2017).…”

Aim: Gracilaria dura, a red agarophyte, is known for its high-quality agarose content and holds significant potential for commercial applications in aquaculture-related industries. The successful commercial utilization of seaweeds relies heavily on obtaining high-quality seed material with commercially valuable traits. Methodology: This study focuses on employing a functional trait-based approach to develop superior strains of G. dura for commercial aquaculture in India. Cultivation through an open sea farm, variations in growth, agar yield, pigments, antioxidant capacity, and primary productivity among the strains were observed. Results: The daily growth rate ranged from 0.5 to 3.5% per day, while pigment content exhibited variations in the Chlorophyll-a, R-Phycocyanin, and R-Phycoerythrin contents. Antioxidant capacity and gross primary productivity also displayed diverse ranges. From a total of 38 strains of G. dura, three were selected based on their growth and other functional traits, namely ADI0221201, VER0220090, and ADI0221202. Positive correlations were identified between growth and regeneration, as well as growth and Chl-a. Agar content showed a positive association with antioxidant capacity and productivity. 1H NMR analysis identified 12 metabolites as potential biomarkers for G. dura growth. Interpretation: All three selected strains hold promise for future commercial cultivation of Gracilaria dura. Furthermore, six additional strains were selected based on their higher growth and agar yield for targeted breeding and hybridization to enhance desirable traits.
