The complete chloroplast (cp) genome of Caulerpa sertularioides f. longipes was first assembled and characterized using Illumina pair-end sequencing from the South China Sea. It is 133,626 bp long, with a GC content of 32.94%. In total, 92 genes were identified in the genome, and they consisted 60 protein-coding genes (PCGs), 30 tRNA genes, and 2 rRNA genes. Like other species in Caulerpa, the whole cp genome of C. sertularioides f. longipes did not demonstrate an obvious quadripartite structure. A total of 31 microsatellites (SSRs) were identified in the cp genome using MISA. A phylogenetic tree revealed that C. sertularioides f. longipes was closer to Caulerpa cupressoides, which further clarified the phylogenetic relationships of species in Caulerpa. ARTICLE HISTORY

“…While C. sertularioides shown the ability to inhibit free radicals more than 10 percent compared to red algae and brown algae. [13] In addition, the oligosaccharide extracted from C. racemose, was also found in the form of α-(14) glucose after being hydrolyzed, and have been classified as gluco-oligosaccharides which can be a good source of carbohydrates for bacteria to grow.

Sea grapes or green cavier (Caulerpa lentilifera), a common tropical green seaweed, consisted of polysaccharides to be used as a prebiotic precursor for prevention of pathogens in aquatic animals. The efficiency of polysaccharides extracted from sea grapes for prebiotic properties was conducted by comparing the growth of probiotic bacteria Bacillus subtilis at different concentrations in co-cultured with pathogenic bacteria Vibrio parahaemolyticus, a gram-negative motile bacterium that inhabits marine and estuarine environments throughout the world, causes of violent diseases outbreak in aquatic animals. The experimental research was 4 treatments with 4 replications including control group (LB broth), extracted sea grape enrichment in LB broth at 0.5, 1.0 and 2.7 mg.C/l. The result showed that the highest growth of probiotic bacteria appeared significantly at extracted sea grape in LB broth with 0.5 mg.C/l (1.64×107 ± 6.04×106 cfu/ml). The said concentration was used as benchmark to clarify the pathogenic resistance. The comparison between monoculture of probiotic bacteria and co-culture of probiotic bacteria plus pathogenic bacteria indicated that there was non significantly different in growth of the bacterias. Hence extracted polysaccharides from sea graps (C. lentilifera) had potential to be utilized not only as a growth enrichment of probiotic bacteria but also inhibiting pathogenic bacteria.

“…And it exhibited approximate effect of aspirin (Arenajo et al, 2017). Shevchenko et al (2009) extracted three polysaccharide fractions, water-soluble P1, P2 and base-soluble P3. The molecular weights of these polysaccharides were 20-60 KDa, 20-40 KDa and more than 70 KDa, respectively.…”

The edible seaweed Caulerpa lentillifera, a powerful natural food source that is rich in protein, minerals, dietary fibers, vitamins, saturated fatty acids and unsaturated fatty acids, has been mass cultured in some Asian countries and has been the focus of researchers in recent years. Here, the operational conditions of its culture, application in wastewater treatment, and bioactive components are summarized and comparatively analyzed. Based on previous studies, salinity, nutrient concentrations, irradiance and temperature are stress factors for algal growth. Moreover, dried Caulerpa lentillifera seaweed is efficient in the biosorption of heavy metals and cationic dyes in wastewater, and fresh seaweed can be introduced as a biofilter in aquaculture system treatment. In addition, among the rich bioactive compounds in Caulerpa lentillifera, the phenolic compounds show the potential ability for regulating glucose metabolism in vivo. Polysaccharides and oligosaccharides exhibit anticoagulant, immunomodulatory effects and cancer-preventing activity. Siphonaxanthin is a compound with attractive novel functions in cancer-preventing activity and lipogenesis-inhibiting effects. Furthermore, the antioxidant activity of siphonaxanthin extracted from Caulerpa lentillifera could be stronger than that of astaxanthin. This review offers an overview of studies of Caulerpa lentillifera addressing various aspects including cultivation, wastewater treatment and biological active components which may provide valuable information for the cultivation and utilization of this green alga.
