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...

The lipid composition of five species of green seaweeds (Chaetomorpha linum, Rhizoclonium riparium, Ulva intestinalis, Ulva lactuca, and Ulva prolifera) grown in fish pond aquaculture systems was studied. In particular, the overall fatty acid (FA) profile and the FA profile of each main lipid class found in these seaweed species were thoroughly analyzed. It was found that every seaweed had a sp...

Ulva lactuca is a functional food ingredient with high antioxidant content. The presence of heavy metal contaminants in natural needs to be eliminated. was investigated for its potential as nephroprotector female Wistar rats. study assessed Blood Urea Nitrogen (BUN) levels, creatinine and kidney histopathology. experiment included Group I (control), II (administered 1000 mg/Kg BW/day lactuca), ...

Chromium was not required for normal growth of romaine lettuce (Lactuca sativa L. subsp. longifolia), tomato (Lycopersicon esculentum Mill.), wheat (Triticum aestivum L.), or bean (Phaseolus vulgaris L.) in solution culture containing 3.8 x 10(-4) muM Cr. Plants grown on this purified nutrient solution contained an average of 22 ng Cr/g dry weight. Duckweed (Lemna sp.) grew and reproduced norma...

Candidate effectors from lettuce downy mildew (Bremia lactucae) enable high-throughput germplasm screening for the presence of resistance (R) genes. The nonhost species Lactuca saligna comprises a source of B. lactucae R genes that has hardly been exploited in lettuce breeding. Its cross-compatibility with the host species L. sativa enables the study of inheritance of nonhost resistance (NHR). ...

Bismuth is a heavy metal whose biogeochemical behaviour in the marine environment is poorly defined. In this study, we exposed three different species of macroalga (the chlorophyte, Ulva lactuca, the phaeophyte, Fucus vesiculosus, and the rhodophyte, Chondrus crispus) to different concentrations of Bi (up to 50 μg L(-1)) under controlled, laboratory conditions. After a period of 48-h, the phyto...

Bioelectricity production from a phytoplankton, Chlorella vulgaris, and a macrophyte, Ulva lactuca was examined in single chamber microbial fuel cells (MFCs). MFCs were fed with the two algae (as powders), obtaining differences in energy recovery, degradation efficiency, and power densities. C. vulgaris producedmore energy generation per substrate mass (2.5 kWh/kg), butU. lactucawas degraded mo...

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±...
