BACKGROUND AND OBJECTIVES Leishmaniasis is a protozoan parasitic disease which is transmitted by the female Phlebotomus sand fly and is prevalent in four continents.The first-choice treatment for the leishmaniasis is pentavalent antimonials, which are potentially toxic and often ineffective and use of them exhibit therapeutic failure. These pharmaceutical problems point towards the need to deve...
BACKGROUND Marine algae, also called seaweeds, are abundantly present in the coastal area of Iran, especially in Persian Gulf. These plants contain important phytochemical constituents and have potential biological activities. The present study investigated the presence of phytochemical constituents and total phenolic quantification of the seaweeds Gracilaria salicornia and Gracilaria corticata...
This paper presents the biosorption of zinc from aqueous solutions using Gracilaria corticata (red algae) powder as a biosorbent. The equilibrium studies on biosorption of Zinc are carried out in batch process. The extent of removal depends on initial concentration of Zinc ion, pH, dosage, temperature etc. The optimum dosage is 15 g/L at the equilibrium agitation time of 60 min. The % biosorpti...
BACKGROUND Seaweeds are taxonomically diverse benthic algae, which are rich in bioactive compounds. These compounds have a potential application in medicine. OBJECTIVES The aim of the study was to investigate the bioactive properties of three seaweed samples, Enteromorpha antenna, Enteromorpha linza and Gracilaria corticata were collected from the shoreline of Mahabalipuram, Tamilnadu. MATE...
Abstract In this study, a 2×3 factorial design with two levels of shrimp density (25 and 50 shrimp per m-2) and three levels of red algae density (0, 200 and 400g per m-2) was applied to calculate nitrogen and phosphorous budgets in integrated culture of Litopenaeus vannamei with Gracilaria corticata during 45 days under zero water exchange system. Juvenile of L.vannamei (5.82 ± 0.11 g...
Selective macroalgae comprising green algae (Ulva lactuca), brown (Padina gymnosphora, Sargassam wightii, Turbinaria ornate) and red (Gracilaria corticata, Halimeda macrolopa, Halymenia dilatata, Gracilaria crassa) were collected from Gulf of Mannar, India. Taxonomic molecular identification affirmed the identity microalgal species. Free fatty acids Fatty Acid Methyl Ester (FAME) synthesis by t...
The antibacterial activity of crude extracts of Sargassum longifolium and Gracilaria corticata collected from the Gulf of Mannar Coast, Tamilnadu, India against common shrimp pathogens were tested by disc diffusion method. Three different solvents namely aqueous, ethanol and methanol were used for extraction. The qualitative phytochemical analysis revealed the presence of carbohydrates, protein...
Epiphytic and endophytic bacteria associated with green macroalgae Ulva (U. fasciata and U. lactuca) and red macroalgae Gracilaria (G. corticata and G. dura) have been identified from three different seasons to evaluate the effect of quorum sensing (QS) molecules on carpospores liberation from Gracilaria dura. The bacterial isolates belonging to the orders Bacillales, Pseudomonadales, Alteromon...
For the investigation of bioactive components from Sri Lankan seaweeds, three species of red algae (Chondrophycus ceylanicus, Gelidiella acerosa, Gracilaria corticata), two species of green algae (Chaetomorpha crassa, Caulerpa racemosa) and one species of brown algae (Sargassum cassifolium) were evaluated. For the bioactivity evaluations, total phenol content (TPC), free radical scavenging acti...
