“…The characterization of macroalgae and seagrass assemblages shows poor coverage for all species in the invasion area (Bentaallah et al 2021). In a study area in the Adriatic Sea (Italy), a greater abundance of C. cylindracea on the sand and detrital substrates is recorded (Pierucci et al 2019). This is confirmed by a recent study by Sghaier et al (2015), along the Tunisian coast, indicating a very high presence of C. cylindracea on sandy substrates, as well as the places of rocks and P. oceanica meadows.…”

“…The effect of this alga on benthic communities was described by Piazzi et al (2016), highlighting some main direct and indirect factors affecting the spread of this taxon, many of which are still poorly understood. For example, the relevance of depth, water movement, herbivores and other invaders in the dispersal dynamics of this pest is still unclear (Pierucci et al 2019). Whereas, these communities play a significant role as environmental indicators because they have different levels of sensitivity to pollution (Kelly et al 2017).…”

Abstract. Ghellai M, Bachir-Bouiadjra MEA, Dahloum L, Megharbi A, Bachir-Bouiadjra B. 2021. Distribution of phytobenthosis in the presence of an invasive alga Caulerpa cylindracea on the Algerian west coast. Biodiversitas 22: 5644-5653. We have targeted and followed the speed of expansion of Caulerpa cylindracea Sonder 1845 through visiting sixteen sites on the Algerian west coast, out in five provinces which are; Tlemcen, Aïn Témouchent, Oran, Mostaganem and Chlef, where it was listed in eight stations; the coastal lines of Oran and Mostaganem, and in a single station in the province of Aïn Témouchent. The phytosociological surveys were established, made it possible to see the frequency of each identified taxon, mentioning a high degree of disturbance in the appearance of benthic macrophytes regarding the dominance of the invasive species. The calculation of the Shannon index and equitability identify the ecological state of the sites, varies from average (H’ around 3.29 for sites little and not invaded by Caulerpa) to poor (H’: 1.74 for Salamandre), with low macrophytic biodiversity (0.4?E?0.64). The calculation of the Caulerpa racemosa (ICar) index on sandy to rocky substrates with algae does not appear to be a limiting factor for the spread of the invasive species. The previous analyses were validated statistically using Factorial correspondence analysis (FCA), Ascending hierarchical classification (AHC), Principal component analysis (PCA), justifying the unbalanced state according to the degrees of pollution.

“…The Caulerpa genus consists of approximately 75 species of tropical to subtropical siphonous green seaweed [3]. Some Caulerpa species, such as Caulerpa cylindracea and Caulerpa taxifiolia, may cause serious environmental damage as invasive species [4]. Caulerpa lentillifera, known as "sea grapes" [5], grown commercially in ponds and consumed in the Philippines, Indonesia and Vietnam, contains proteins, minerals, dietary fibre, vitamins, and saturated and unsaturated fatty acids [6].…”

Caulerpa lentillifera (Sea Grapes) Improves Cardiovascular and Metabolic Health of Rats with Diet-Induced Metabolic Syndrome

Caulerpa lentillifera (sea grapes) is widely consumed in South-East Asia as a low-energy food with high contents of vitamins and minerals. This study investigated dried sea grapes containing 16.6% insoluble fibre commercially produced in Vietnam as an intervention. We hypothesised that insoluble fibre is the primary metabolite that will reverse diet-induced metabolic syndrome. Male Wistar rats (n = 48) were randomly allocated to four groups in a 16 week protocol. Two groups were fed either corn starch (C) or high-carbohydrate, high-fat (H) diets for the full 16 weeks. The other two groups received C and H diets for eight weeks and then received C. lentillifera added to these diets for the final eight weeks (CCL and HCL, respectively). High-carbohydrate, high-fat diet-fed rats developed obesity, hypertension, dyslipidaemia, fatty liver disease and increased left ventricular collagen deposition. C. lentillifera supplementation in HCL rats decreased body weight, systolic blood pressure, plasma concentrations of total cholesterol and non-esterified fatty acids, inflammatory cells in heart and liver, and visceral adiposity. The Firmicutes to Bacteroidetes ratio decreased in the gut microbiota of HCL rats. Therefore, C. lentillifera attenuated cardiovascular and metabolic symptoms of metabolic syndrome in rats, possibly by preventing infiltration of inflammatory cells together with modulating gut microbiota.

“…The lack of information about sulfated polysaccharides from such an important and widely distributed algal genus, comprising at least 75 species, some of which of them having invasive nature ( Galil, 2007 ; Pierucci et al, 2019 ), is noteworthy. Also noteworthy is the variety of structures proposed in the few investigations published for the different species of the same genus.…”

Diversity of Sulfated Polysaccharides From Cell Walls of Coenocytic Green Algae and Their Structural Relationships in View of Green Algal Evolution

Seaweeds biosynthesize sulfated polysaccharides as key components of their cell walls. These polysaccharides are potentially interesting as biologically active compounds. Green macroalgae of the class Ulvophyceae comprise sulfated polysaccharides with great structural differences regarding the monosaccharide constituents, linearity of their backbones, and presence of other acidic substituents in their structure, including uronic acid residues and pyruvic acid. These structures have been thoroughly studied in the Ulvales and Ulotrichales, but only more recently have they been investigated with some detail in ulvophytes with giant multinucleate (coenocytic) cells, including the siphonous Bryopsidales and Dasycladales, and the siphonocladous Cladophorales. An early classification of these structurally heterogeneous polysaccharides was based on the presence of uronic acid residues in these molecules. In agreement with this classification based on chemical structures, sulfated polysaccharides of the orders Bryopsidales and Cladophorales fall in the same group, in which this acidic component is absent, or only present in very low quantities. The cell walls of Dasycladales have been less studied, and it remains unclear if they comprise sulfated polysaccharides of both types. Although in the Bryopsidales and Cladophorales the most important sulfated polysaccharides are arabinans and galactans (or arabinogalactans), their major structures are very different. The Bryopsidales produce sulfated pyruvylated 3-linked β- d -galactans, in most cases, with ramifications on C6. For some species, linear sulfated pyranosic β- l -arabinans have been described. In the Cladophorales, also sulfated pyranosic β- l -arabinans have been found, but 4-linked and highly substituted with side chains. These differences are consistent with recent molecular phylogenetic analyses, which indicate that the Bryopsidales and Cladophorales are distantly related. In addition, some of the Bryopsidales also biosynthesize other sulfated polysaccharides, i.e., sulfated mannans and sulfated rhamnans. The presence of sulfate groups as a distinctive characteristic of these biopolymers has been related to their adaptation to the marine environment. However, it has been shown that some freshwater algae from the Cladophorales also produce sulfated polysaccharides. In this review, structures of sulfated polysaccharides from bryopsidalean, dasycladalean, and cladophoralean green algae studied until now are described and analyzed based on current phylogenetic understanding, with the aim of unveiling the important knowledge gaps that still exist.
