Comparison the cytotoxic effects of Ulva fasciata and lactuca on MCF-7 MDA-MB-231breast cancer cell lines

the study aimed to come up with a list of specific macroalgae species, which could be used to biomonitor specific metal elements in the coastal waters of east africa. water extraction, edta, aqua regia extraction and optimized bcr 3-step sequential extracts were used to mimic bioavailable metals under various environmental conditions. the results indicated that ulva lactuca could be used as a ...

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.

Ulva is a common component of marine intertidal flora in Australia with many species frequently observed along the Queensland coastline. Three species of Ulva, U. lactuca, U. intestinalis and U. prolifera were found to naturally occur at the Bribie Island Research Centre (BIRC) in Southeast Queensland. Studies were undertaken to establish the most optimal conditions for growing Ulva in the BIRC...

The nutritional composition of the edible seaweeds Durvillaea antarctica (frond and stem) and dried Ulva lactuca was determined, including the soluble (SDF), insoluble (IDF) and total (TDF) dietary fiber content, amino acid and fatty acid profiles along with tocopherols and tocotrienols (pro-vitamin E). Results show that U. lactuca contained 60.5 ± 1.5%, and D. antarctica frond and stem 71.4 ± ...

Two experimental feeding trials were conducted during four weeks to evaluate the use of Ulva lactuca in shrimp culture: (1) for wastewater bioremediation, and (2) using different inclusion levels of U. lactuca meal in shrimp feed. In feeding trial 1, shrimp reared under seaweed U. lactuca water exchange in a re-circulation system (SWE) resulted in similar growth and feed utilization as shrimp r...

In vitro antioxidant activity of Ulva lactuca (Chlorophyta) and three brown seaweeds belonging to the division Phaeophyta were evaluated. The species Padina pavonica, Colpomenia sinuosa, Cystoseira myrica and U. lactuca were collected during low tide between March and June 2012 from the coastline of the Persian Gulf (Hormozgan and Bushehr provinces), Iran.Ethyl acetate, n-Hexane and methanol e...

The effects of nutrient supply on photosynthesis (estimated as chlorophyll fluorescence), chlorophyll content, biomass yield and proximate chemical composition of tank cultivated Ulva lactuca L. (Chlorophyta) were evaluated. To assess the effect of nutrient supply on resistance capacity against short-term stress, algae grown in high nutrient supply (HNS) fishpond effluents and in low nutrient s...

This study aimed to evaluate the effects of diet containing the green macroalgae, Ulva lactuca, on the growth performance, feed utilization and body composition of African catfish Clarias gariepinus. Four experimental diets were formulated: D1 as a control group and D2, D3 and D4 which included 10%, 20% and 30% U. lactuca meal, respectively. 180 African catfish, weighing 9.59 ± 0.43 g, and with...
