E.A. Thallus consist of creeping stolons (0.6–1.25 mm in diameter) bearing numerous descending delicate rhizoids and erect branches at distance 4–8(–13) mm from each other. Ellen Lavoie1, Scott Braswell2 1,2: University of Washington, Molecular Analysis Facility, MolES, Seattle, WA Introduction: Caulerpa is a genus of tropical marine algae within the phylum Chlorophyta ... provide and increase in surface area GC-MS analysis also revealed the existence of hydrocarbon compounds in purified fractions of C. glomerata with antibacterial activity.111, Monounsaturated fatty acid, (9Z)-hexadecenoic acid, and the relatively unusual PUFA (6Z,9Z,12Z)-hexadecatrienoic acid were isolated from P. tricornutum. Via column chromatography, reverse-phase HPLC, and H-NMR spectroscopy, the PUFA eicosapentaenoic acid (EPA) was identified as an antimicrobial compound active against a broad spectrum of microorganisms, including MDR S. aureus bacterium.110, Postoperative infections can cause serious problems, including failure of the surgical procedure, other surgical complications, organ failure, and death. For example, Ulva spp. Aside from their food use, the Japanese have made and marketed ‘Kombu-Cha’ – a kind of tea made out of processed Laminaria. Caulerpa toxins, namely, caulerpin and caulerpinic acid, have also been shown to have insecticidal activity against the common house mosquito Culex pipiens (Alarif et al., 2010). Thallus light to dark green, consisting of creeping slender stolons 1(–2) mm in diameter, bearing branched rhizoids and erect branches 1–3 cm high. Destructive methods require the removal of the macroalgae and the substratum (bottom materials, seagrasses) in a quadrat from the site (Barnes 1980, Heijs 1987). Sampling of macroalgae in such variable habitats may require various sampling strategies. Genus Caulerpa Species Caulerpa cupressoides. form, In the growing stage, they form surfaces varying be- tween 0.5 to 6 m2 and located 20 to 100 m from each other. In the United States it is found from North Carolina to Florida. The tender tops of Sargassum and Hormophysa are cooked with vegetables; Cladosiphon and Laminaria are relished as soup preparations. The genus Caulerpa is highly diverse, especially in the Caribbean Sea, the Indo-Malay archipelago and the temperate waters of southern Australia. Gian Powell B. Marquez, ... Tatsuya Hasegawa, in Seaweed Sustainability, 2015. GENUS Caulerpa (Gk. Codium fragile, also considered as a notorious invader, was found growing on eelgrass rhizomes in Canada. New Chlorophyceae, new Rhodophyceae and miscellaneous notes as published in the Bulletin of the Torrey Botanical Club. Creeping stolons are dark green, (1)–1.5–2.5 mm in diameter and bearing descending delicate rhizoids. In seagrass meadows, both the bottom (sand, mud, rocks, coral rubbles) and seagrasses themselves act as substrata for macroalgae (Phillips 1978, Phillips et al. Branches 2.5–5(–20) cm high, 4–5(–20) mm wide, stalked (1–3 mm high). Specimens from this area corresponded well to the Caulerpa strain previously reported as C. taxifolia from Turkey (Cevik et al., 2007) and C. taxifolia var. Caulerpa serrulata in association with the red alga Hypnea pannosa occupied the live coral Stylophora pistillata. Moreover, green seaweeds are known to produce extensive blooms in eutrophic waters. Rhizoids fine, branched. Distribution. Growing on hard substrates covered with sand and on sandy bottom. It is no wonder that sea vegetable is now known as the poor man's source of cheap protein and iodine, and has an export potential for tropical countries. Caulerpa species are eaten as delicacies in some Pacific countries, 89 and it was the search for the distinctive “peppery principle” of C. racemosa that led the initial investigation into this genus. was initially incorrectly assigned as a phenazine derivative (172)89 with the structure later being revised90 and confirmed by X-ray crystallography91 as 173, featuring two indole moieties fused to a central cyclooctatetraene diester moiety90,91 (Figure 1.15). Organic extracts from Caulerpa prolifera inhibited the growth of two gram-positive and one gram-negative unidentified marine bacteria (Smyrniotopoulos et al., 2003). 1982, Ogden and Ogden 1982, Fonseca and Fisher 1986, Heijs 1987, Bell and Pollard 1989, Borowitzka and Lethbridge 1989, Verheij and Erftemeijer 1993, Jupp et al. The rhizoids stalked, repeatedly branched, and tapering to slender apices. In Australia, Paul et al. Caulerpin was found to be slightly less active against HSV-1 than acyclovir but slightly more selective for HSV-1 over vero cells and hence less cytotoxic.113 In the BVDV assay, 173 proved to be more active than acyclovir, again with greater selectivity. Caulerpa taxifolia (Vahl): Caulerpa taxifolia (Killer Algae) is a light green macroalgal grow up to 2.8 m height in 40-60 cm deeper of tropical seas, 6-8 mm diameter of flattened upright leaf-like frond arising from the creeping stolons up to 3-15 cm long and from the base, the narrow tip upward small side branchlets are constructed opposite to the midrib 47, 48 Fig. Branches dark green, simple or occasionally branched, ending abruptly in a short apex, shortly stalked, feather-like, oblong or broadly lanceolate, dwarf, 1–3 cm high, 4–8(–10) mm broad, with flat midrib, 1–3 mm broad and with pinnules on both sides of the midrib. Thallus bright dark or grass green consists of widely spreading stolons bearing erect branches above and rhizoids below. The Chinese and Japanese are among the prolific seaweed-eating people, and are accredited with recognizing its food value. (2014) reported similar biomass yield values from the same species cultured in raceway. So if diffusion time increases with size, it’s going to make the cell into one hot mess. Species diversity indices combine both species richness and evenness into a single value (e.g., Shannon's Index, for details refer to the end of this Chapter). Titlyanov, ...
