The removal efficiency for Cd (II) by the marine algae Ulva fasciata and Ulva lactuca was studied at different culture conditions. The maximum biosorption capacities were 8.353 and 8.804 mg g−1 dwt for U. fasciata and U. lactuca, respectively, at optimum conditions for each alga.

Studies on urease extracted from Ulva lactuca
Hydrobiologia, 1984Urea is an excellent nitrogen source for the growth of many algae (Syrett 1962; Naylor 1970). In algae, the enzymes which degrade urea are urease and ATP: urea amidolyase (U ALase) (Leftley & Syrett 1973). The properties of urease and U ALase are obviously different; consequently, they can be easily distinguished in extracts. U ALase requires ATP, Mg2+,

Studies on the constituents of the green alga Ulva lactuca
Chemistry of Natural Compounds, 2011Phytochemical investigations on a marine green alga Ulva lactuca led to the isolation of two new compounds (E)-6-heptacosen-5-one (1) and (E)-6-octadecen-5-ol (2), along with four known compounds, (Z)-10-hexacosene (3), docosanoic acid (4), palmitic acid (5), and isofucosterol (6).

The influence of temperature and illumination on the exchange of potassium ion in Ulva lactuca
Biochimica et Biophysica Acta, 1953Abstract 1. 1. Methods for the use of 42K in studying teh exchange of potassium ion in the green alga Ulva lactuca are described, and the effects of illumination and temperature on the dynamics of this exchange are presented. 2. 2. Conditions of illumination or increased temperature each markedly increases the exchange rate. 3. 3.

Osmotic adaptation in Ulva lactuca under fluctuating salinity regimes
Planta, 1982A study has been made of the osmotic responses of the green intertidal alga, Ulva lactuca, under two fluctuating salinity regimes; sinusoidal and square-wave fluctuations between 30 and 100% sea water in a 12 h cycle. These regimes closely resemble the tidal fluctuation of salinity encountered by the alga in its natural estuarine habitat.

Potential of Macroalgae Ulva lactuca as a Source Feedstock for Biodiesel Production
Recent Patents on Food, Nutrition & Agriculture, 2017The aim of this study was to investigate the possibility of growing of algae Ulva lactuca L.under different salinity levels coupled with varied KNO3 concentrations (source of N) as a potential source of oil for biodiesel production.U. lactuta was cultured in 10.0% NaCl coupled with either 2.5 g/L (S1+ 1N) or 1.0 g/L KNO3 (S1+ 2N) and in 30.0% NaCl ...
