Isolation and structure determination of algicidal compounds from Ulva fasciata.
Thirty-seven species of seaweeds including 10 Chlorophyta, 13 Phaeophyta, and 14 Rhodophyta collected from the coast of Nagasaki Prefecture, Japan, were screened for algicidal activity against the red-tide phytoplankton Heterosigma akashiwo. The green alga Ulva fasciata (Ulvaceae, Chlorophyta) showed the strongest algicidal activity among the seaweeds tested. Bioassay-guided fractionation of th...
متن کاملIsolation and identification of antibacterial steroid compounds from Ulva fasciata in the Persian Gulf
Due to numerous reasons, marine-obtained resources have attracted the interest of researchers. One of the subjects attracted the interest of researchers in recent years in the field of biologist marine algae due to their nutritional value, their benefits for health and their biological activities. In this study, the powder was extracted using acetone, then the extract purified by silica gel col...
متن کاملAnticancer Activity of Methanolic and Aqueous Extract of Ulva Fasciata in Albino Mice
Seaweeds are primitive non flowering aquatic plants, which have been a source of food, feed and medicine since ancient times. The selected green seaweed U. fasciata collected from Gulf of Mannar is a unique marine habitat that belongs to the diverse class of seaweeds. Hence the present study was conducted with the specific objectives to explore the anticancer activity of green seaweed, Ulva fas...
متن کاملPhotosynthesis in Ulva fasciata: V. Evidence for an Inorganic Carbon Concentrating System, and Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase CO(2) Kinetics.
Evidence of an inorganic carbon concentrating system in a marine macroalga is provided here. Based on an O(2) technique, supported by determinations of inorganic carbon concentrations, of experimental media (as well as compensation points) using infrared gas analysis, it was found that Ulva fasciata maintained intracellular inorganic carbon levels of 2.3 to 6.0 millimolar at bulk medium concent...
متن کاملSelective toxic effects of polyunsaturated fatty acids derived from Ulva fasciata on red tide phyotoplankter species.
Alpha-linolenic acid and linoleic acid isolated from Ulva fasciata showed toxic effects on red tide phytoplankters in a concentration-dependent manner. Among six species tested, raphidophycean flagellate Heterosigma akashiwo was the most susceptible to these fatty acids, and 50% lethal concentrations (LC50) of alpha-linolenic acid and linoleic acid were estimated to be 0.58 and 1.91 microg/ml r...
