Toxicity of Synthetic Surfactants to the Marine Macroalga, Ulva lactuca
The toxicities of three synthetic surfactants to the marine macroalga, Ulva lactuca, have been examined by monitoring chlorophyll a fluorescence quenching. The anionic surfactant, sodium dodecyl sulphate (SDS), exerted no measurable toxicity over the concentration range 0–10 mg L, while presence of the non-ionic surfactant, Triton X-100 (TX), elicited a small reduction in photochemical efficien...
متن کاملLow densities of epiphytic bacteria from the marine alga Ulva australis inhibit settlement of fouling organisms.
Bacteria that produce inhibitory compounds on the surface of marine algae are thought to contribute to the defense of the host plant against colonization of fouling organisms. However, the number of bacterial cells necessary to defend against fouling on the plant surface is not known. Pseudoalteromonas tunicata and Phaeobacter sp. strain 2.10 (formerly Roseobacter gallaeciensis) are marine bact...
متن کاملNitrate and phosphate regimes induced lipidomic and biochemical changes in the intertidal macroalga Ulva lactuca (Ulvophyceae, Chlorophyta).
This study was carried out in order to understand the lipid and biochemical alterations resulting from different nutritional regimes of nitrate and phosphate in Ulva lactuca. The algal thalli cultured in artificial seawater (ASW) showed higher levels of carbohydrates and non-polar lipids and increased phosphatase activities, accompanied by degradation of polar lipids, proteins and pigments. Fur...
متن کاملStudy of L-Asparaginase Production by Streptomyces noursei MTCC 10469, Isolated from Marine Sponge Callyspongia diffusa
L-asparaginase is an anti-neoplastic agent used in the chemotherapy of lymphoblastic leukaemia. The present work deals with production of extra-cellular Lasparaginase from marine actinomycetes, using submerged fermentation. Marine actinomycete Streptomyces associated with marine spongeCallyspongia diffusa was isolated using specific ISP medium. Sponge-associated Streptomyces was character...
متن کاملBioactivity potential of some marine algae from south of Iran
Algae are composed of a diverse group of various aquatic organisms. Secondary or primary metabolites from these organisms may be potential bioactive compounds of interest for use in the development of new pharmaceutical agents. In this research, four species of marine algae, Ulva lactuca, Padina pavonica, Colpomenia sinuosa and Cystoseira myrica, isolated from Persian Gulf coasts were evaluated...
