The influence of sulfathiazole on the macroalgae Ulva lactuca.

Bioremediation 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...

Huxley College of the Environment An Evaluation of Environmental Influences on Tributyltin Toxicity Using the Macroalgae Ulva lactuca

Uptake of urea and amino acids by the macroalgae Ulva lactuca (Chlorophyta) and Gracilaria vermiculophylla (Rhodophyta)

Dissolved organic nitrogen (DON) makes up a large fraction of the total dissolved nitrogen pool in coastal waters, but is often ignored as a potential nitrogen source for primary producers. In laboratory experiments, we measured the uptake of small, labile DON compounds, urea and a variety of different amino acids, by the common estuarine macroalgae Ulva lactuca and Gracilaria vermiculophylla. ...

Potential use of green macroalgae Ulva lactuca as a feed supplement in diets on growth performance, feed utilization and body composition of the African catfish, Clarias gariepinus.

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...

Biochemical Composition of Marine Macroalgae from Gangetic Delta at the Apex of Bay of Bengal

Variations in protein, lipid, carbohydrate and astaxanthin content of Enteromorpha intestinalis, Ulva lactuca and Catenella repens were documented over a 10 months period from September 2007 to June 2008. The macroalgal species were collected from six sampling stations of Indian Sundarbans, a Gangetic delta at the apex of Bay of Bengal. On dry weight basis, the protein content varied from 4.15±...
