“…Caulerpa racemosa growing in three earthen ponds ( n = 3) at Tanjung Kupang, Johor, approximately 1 kg wet weight (kg w/w ) each, was hand-picked and treated separately with assistance from volunteers of the Kelab Alami Mukim Tanjung Kupang in January 2018. Samples identification was confirmed based on morphological identification and description from Verlaque et al [ 19 ], Belleza and Liao [ 20 ] and Zubia et al [ 21 ]. A herbarium voucher (UMTP1901) was stored at the Faculty of Marine and Environmental Sciences herbarium of Universiti Malaysia Terengganu.…”

Caulerpa racemosa (Forsskal) J. Agardh is a green seaweed used as food and folk medicine since ancient times in the Indo-Pacific region, particularly in southeast Asia. In this study, the proximate nutrient composition, phytochemical, anti-oxidant and anti-diabetic properties of sea grape C. racemosa collected from culture fishponds in Johor, Malaysia were analysed. The contents (dry weight basis) of carbohydrate, crude protein, crude lipids, ash and caloric value obtained were 33.42 ± 1.34%, 20.27 ± 0.14%, 4.20 ± 0.32%, 28.25 ± 0.27% and 2544.67 ± 7.04 cal g−1, respectively. The amino acid score (AAs) and biological protein value (213.43 mg g−1) indicated that C. racemosa presented a better protein quality. The most abundant fatty acids were C16:0 (palmitic acid: 63.27%), followed by C18:1 (oleic acid: 5.80%), and C18:2 ῳ6 (linoleic acid: 5.33%). The analysis of the ash content indicated that essential minerals and trace elements, such as Ca, Fe, and Mn, were present in the seaweed. The total phenolic content (TPC) and total flavonoid content (TFC) observed in the ethyl acetate extract were 17.88 ± 0.78 mg GAE g−1 and 59.43 ± 2.45 mg QE g−1, respectively. The ethyl acetate extract of C. racemosa demonstrated notable anti-diabetic activity in diabetic induced rats. The low (100 mg kg−1) and high (200 mg kg−1) doses of cultivated C. racemosa extract exhibited a significant decrease (p < 0.05) in blood glucose levels while preventing weight loss, reducing plasma AST, ALT levels as a sign of hepatoprotective effect and recording albumin levels similar to positive control in diabetic induced rats. The results support the usefulness of cultivated C. racemosa as a potential functional food.

“…The genus Caulerpa (Chlorophyta: Bryopsidales) is a group of marine green siphonous algae distributed in tropical and subtropical regions (Ratana-arporn and Chirapart 2006). It includes more than 100 species (Zubia et al 2020) and is considered as one of the most widespread, conspicuous and abundant groups of seaweeds worldwide (Silva 2003).…”

Comparative evaluation of multiple protein extraction procedures from three species of the genus Caulerpa

et al. 2021

View full text Add to dashboard Cite

The aim of this study was to define the simplest and least expensive protocol for total protein extraction for three different macroalgae of the genus Caulerpa (the invasive C. taxifolia and C. cylindracea and the autochthonous C. prolifera). Five multi-step protein extraction procedures, set up for other macroalgal species, were tested. For each of them, different pre-treatment and extraction conditions were simultaneously examined, according to a factorial design, considering the starting material, the solvent-to-biomass ratio, and the incubation temperature. Protein yield in the obtained extracts was estimated with the Bradford method. Further, polyacrylamide gel electrophoresis (SDS-PAGE) was used to resolve proteins, assessing their quality and integrity. Significant differences in protein yield were observed among the extraction protocols and the conditions tested, also in relation to the considered species. Profiles having an acceptable quality were obtained for C. prolifera and C. cylindracea, and from the obtained results, the best method to obtain high yield and quality protein extracts for the two above-mentioned species appears to require the use of a primary TCA/acetone extraction buffer followed by a lysis buffer with NaCl, KCl, urea, Triton, SDS and a protease inhibitor. The best results, in particular, were obtained starting from fresh pulped material with a buffer-to-biomass ratio of 10:1 and an incubation temperature of 4°C. For C. taxifolia, instead, none of the tested protocols produced satisfactory results and further studies will be required.

“…Caulerpa lentillifera are easily and sustainably culturable due to their propagation via fragmentation and the low need for expensive infrastructure or expertise (de Gaillande et al 2017). Sea grapes are in particular cultured in open-tidal ponds as in the Philippines and Vietnam (de Gaillande et al 2017;Zubia et al 2020), and in the latter, pond culture is increasingly implemented at the coasts of the Central South in the Khánh Hòa province. In Japan and China, where the demand for sea grapes is especially high, land-based raceway culture is already practiced to some extent (Long et al 2020;Zubia et al 2020).…”

A major factor during sea grape culture is solar radiation, which can be partially controlled through artificial shading of ponds.…”

Cultured and packed sea grapes (Caulerpa lentillifera): effect of different irradiances on photosynthesis

2020

View full text Add to dashboard Cite

The green macroalga Caulerpa lentillifera (sea grapes, green caviar) is a promising source for future nutrition due to its beneficial composition for human consumption. It is cultured in tidal ponds, mainly in Vietnam and the Philippines, and stored for shipment and retail in plastic containers, like polystyrene (PS) and polyethylene terephthalate (PET), exhibiting different properties. This study investigates the influence of irradiances on the physiology of sea grapes under culture and packaging ambience in PET using pulse-amplitude modulated (PAM) fluorometry. Fv/Fm values of C. lentillifera significantly decreased < 0.54 ± 0.06 standard deviation (SD) after 7 days of culture under 100 μmol photons m−2 s−1, but with the potential of recovery. In packaging ambience in the state of desiccation, sea grapes exposed to room irradiances (3 μmol photons m−2 s−1) for 12 days were still physiologically in a good condition (Fv/Fm = 0.70 ± 0.06). However, 12 days under irradiances of 70 μmol photons m−2 s−1 leads to decreased Fv/Fm (0.42 ± 0.11) and a moisture content of 88.2 ± 3.3% of initial. After re-immersion in sea water under room irradiances, Fv/Fm values recovered to a certain degree. In darkness, desiccation was followed by a decrease of Fv/Fm to 0.09 ± 0.19 and moisture content of 49.3 ± 20.2% of initial with no recovery after re-immersion under room irradiances. Results suggest shading of C. lentillifera in pond culture and PET containers as suitable packaging for sea grapes, but a dim light source should be provided during storage.
