“…In their study, some macroalgae possessed antifungal activity, others antibacterial, and only Laurencia pinnatifida (Rhodomelaceae) exhibited both antifungal and antibacterial activity. Extracts from this rhodophyte also exhibited a strong antifouling activity against microalgae, comparable to that of heavy metals and biocides currently used in antifouling paints (Hellio et al, 2002). Several extracts from other macroalgae were also active.…”

Allelopathy in aquatic environments may provide a competitive advantage to angiosperms, algae, or cyanobacteria in their interaction with other primary producers. Allelopathy can influence the competition between different photoautotrophs for resources and change the succession of species, for exarnple, in phytoplankton cornmunities. Field evidence and laboratory studies indicate that allelopathy occurs in all aquatic habitats (marine and freshwater), and that ail prirnary producing organisms (cyanobacteria, micro-and macroalgae as well as angiospenns) are capable of producing and releasing allelopathically active compounds. Although allelopathy also includes positive (stimulating) interactions, the majority of studies describe the inhibitory activity of ailelopathicaily active compounds. Different mechanisms operate depending on whether allelopathy takes place in the Open water (pelagic zone) or is Substrate associated (benthic habitats). Allelopathical interactions are especiaily common in fully aquatic species, such as submersed macrophytes or benthic algae and cyanobacteria. The prevention of shading by epiphytic and planktonic primary producers and the competition for space may be the ultimate cause for allelopathical interactions. Aquatic ailelochemicals often target multiple physiological processes. The inhibition of photosynthesis of competing primary producers seems tobe a frequent mode of action. Multiple biotic and abiotic factors determine the strength of allelopathic interactions. Bacteria associated with the donor or target organism can metabolize excreted aiielochemicals. Frequently, the impact of surplus or limiting nutrients has been shown to affect the overail production of allelochemicals and their effect on target species. Similarities and differences of ailelopathic interactions in marine and freshwater habitats as well as between the different types of producing organisms are discussed.

“…showed potent algicidal activity (ALAMSJAH et al, 2005). Similarly, Jeong et al (2000) demonstrated that at a concentration of 50µg/ml the methanolic extract of Corallina pilulifera can inhibit the growth of the toxic microalga, Cochlodinium polykrikoides. Being less toxic to the crustaceans, the result obtained in the present study suggests that the extract of A. taxiformis has the potential to eradicate noxious algal bloom in coastal aquaculture ponds.…”

“…It has been reported that chemicals produced by some algalspecies can inhibit the growth both of algae and invertebrates as well as slow or stop larval development of bivalves (NELSON et al, 2003). Many studies have been undertaken to evaluate the antialgal property of seaweeds (TANAKA; ASAKAVA, 1988;LUSTIGMAM;BROWN, 1991;HELLIO et al, 2002). Cho et al (1999) reported that a methanol extract of Ishige sinicola at 200µg/ml greatly inhibited growth of Isochrysis galbana.…”

A B S T R A C TAmong the diverse variety of red algae, Asparagopsis taxiformis constitutes one of the abundant biomass in the Kollam coast (Southwest coast of India). Therefore, in the present study, A. taxiformis was collected, extracted and fractionated using column chromatography. The individual fractions were evaluated in vitro for their antifouling, anticyanobacterial, piscicidal and crustaceans toxicity assays. The fraction eluted with 2:8, petroleum ether and ethyl acetate exhibited strong and broad spectrum of bioactivity. In antifouling assay against Limnea truncatula, the active algal fraction produced 80% of foot repellency at 150 mg/L whereas in anticyanobacterial assay, the active fraction inhibited 100% growth of Trichodesmium sp. at 320 mg/L. The algal fraction showed higher piscicidal effect at the level of 60 mg/L. The crustacean toxicity of the active fraction was also evaluated to find compounds without toxicity in non target organisms, Penaeus monodon and Macrobrachium rosenbergii. It was found that column fraction showed less toxicity against the non target organisms. The chemical constituents of the active fraction were identified by means of chromatographic systems such as TLC, reverse phase HPLC and GC-MS. The overall activity profile envisages that the active column fraction of A. taxiformis might contain synergistic bioactive metabolites that could be utilized for the control of fouling organisms, algal bloom and herbivorous/predaceous fishes in aquaculture ponds. R E S U M OEntre as diversas variedades de algas vermelhas, Asparogopsis taxiformis constitui uma das que apresentam alta biomassa na costa de Kollam (Sudoeste da Índia). No presente estudo A. taxiformis foi coletada, seca e reduzida a pó, após o que foi realizada sua extração e feito o fracionamento usando-se cromatografia por coluna. As frações individuais foram avaliadas in vitro em ensaios para testar sua capacidade anti-incrustante, anticianobacteria e toxicidade para peixes e crustáceos. A fração extraída com eter de petróleo e etil acetato (2:8) apresentou o espectro de bioatividade mais forte e amplo. No ensaio anti-incrustação efetuado com com o molusco pulmonado Limnea truncatula, a fração algal ativa produziu 80% de repelência do pé em 150 mg/l, enquanto que no ensaio anticianobacteria a fração ativa inibiu 100% do crescimento de Trichodesmium sp., em 320 mg/l. A fração algal mostrou o efeito mais intenso contra peixes no nível de 60 mg/l. Em relação aos crustáceos, a toxicidade da fração ativa foi avaliada também visando encontrar compostos não tóxicos para organismos não alvo, tais como Penaeus monodon e Macrobrachium rosembergii. Foi visto que a fração ativa da coluna mostrou menor toxicidade para estas espécies. Os componentes químicos da fração ativa foram identificados por meio dos sistemas cromatográficos, tais como TLC, fase reversa do HPLC e GC-MS. O perfil geral de atividade aponta que a fração ativa da coluna para A. taxiformis pode conter metabolitos bioativos sinérgicos que podem ser utilizados para o c...

“…The survival of this sedentary vegetation has primarily relied on efficient defence mechanism against diverse invaders. Seaweeds from varied locales have been evaluated for a wide range of biological activities, e.g., antibacterial (TUNEY et al 2006), antiviral (SERKEDJIEVA 2004, antifungal (TANG et al 2002) and antialgal activities (HELLIO et al 2002). Over 2,400 secondary metabolites have been isolated and described from the divisions Rhodophyta, Phaeophyta, and Chlorophyta, many of which have been reported to have excellent biological activity (FAULKNER 2001 and references therein).…”

The marine red alga Laurencia brandenii collected from the southwest coast of India (Indian Ocean) was extracted and fractioned using column chromatography. The individual fractions were evaluated in vitro via antimicrobial activity against six species of Microbial Type Culture Collection and three species of clinical human pathogens, antipest activity on Sitophilus oryzae, maggoticidal activity against 2 nd instar larvae of Sarcophaga sp. and termiticidal activity against Microtermes obesi. It was found that the fraction eluted using petroleum ether:chloroform (6:4) exhibited broader biological activities. The phyco-constituents of the active fraction were identified by gas chromatography-mass spectrometry (GC-MS) analysis. The GC-MS profile of the active fraction revealed that the main constituent was octadecadienoic acid (49.75%) followed by n-hexadecanoic acid (14.24%), which might have a functional role in the biological activities. The overall activity profile envisages that these bioactive compounds from L. brandenii could be utilized as a renewable natural resource for the development of novel environmental-compatible formulations for the control of human pathogens, pests, termites and maggots.
