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 کاملThe influence of sulfathiazole on the macroalgae Ulva lactuca.
Sulfonamides (SA) are a class of antibiotics routinely found in environmental matrices and therefore their role as contaminants should be investigated in non-target organisms. With this purpose the present experimental work has evaluated the exposure of the chlorophycean Ulva lactuca L. to sulfathiazole (STZ), a SA drug commonly used in aquaculture, at two concentrations representing prophylact...
متن کاملBioremediation of reject water from anaerobically digested waste water sludge with macroalgae (Ulva lactuca, Chlorophyta).
Phosphorus and biologically active nitrogen are valuable nutrient resources. Bioremediation with macroalgae is a potential means for recovering nutrients from waste streams. In this study, reject water from anaerobically digested sewage sludge was successfully tested as nutrient source for cultivation of the green macroalgae Ulva lactuca. Maximal growth rates of 54.57±2.16% FW d(-1) were achiev...
متن کاملProtective effect of Ulvan from Ulva lactuca against experimentally induced fibrosarcoma in wistar rats
Ulvan, a sulphated polysaccharide has been extracted from the green seaweed, Ulva lactuca. Results showed that ulvan pocesses 59.5% sugars, 16.9% sulphate, 19.5% uronic acid of viscosity of solution is 21(mPa). Functional groups of ulvan have been identified with IR spectrum. The efficacy of ulvan was tested against experimentally induced fibrosarcoma in wistar rats and found to be promising.
متن کاملEvaluation of Nutritional Composition of The Dried Seaweed Ulva lactuca from Pameungpeuk Waters, Indonesia
The nutritional composition of the dried seaweed Ulva lactuca from Pameungpeuk waters, including proximate, vitamins, minerals, dietary fibre and heavy metal has been carried out. The objective of this present study is to know the nutritional composition of the dried seaweed U. lactuca for utilisation in human nutrition in the future. Results show that carbohydrate was the major component in th...
