“…S. horneri of Fukuoka Prefecture (Japan) has no substantial changes in the content of total lipids. A slightly higher content of lipids was shown at the growth of alga (in January and in February, 9.9 -10.1 mg/g of DW), a decrease their content in period maturation (in March and in April, 9.5 and 6.2 mg/g DW respectively), the lowest content was in physiologically old algae (5.26 mg/g DW) [6].…”

“…The content of all complexes of compounds as protein, total dietary fiber, ash, lipids was investigated only in a small number of algae. Foremost, seasonal variations in these nutritional components were investigated in S. horneri taking into account its growth and maturity, as well as seasonal changes in biomass and moisture was estimated [6]. Seasonal variations of total lipids, fatty acid composition, and fucoxanthin contents in details were investigated also for S. horneri [20].…”

The present study describes the content of total lipids (TL), the main components of polar and neutral lipids (NL) and photosynthetic pigments (PSP) in edible seaweed Sargassum pallidum (Ochrophyta) from the Sea of Japan, Russia, in different months of the year, taking into account life cycle. Special attention was paid to the fatty acids (FAs) of total lipids as well as the accumulation of important polyunsaturated fatty acids (PUFAs) in glyceroglycolipids (GL) and reserve lipids in the seasonal cycles of growth. The content of TL strongly varied in the course of a year. The major lipid components were GL (20.3% -36.4%) and NL (19.8% -30.6%), while phospholipids (PL) were present in negligible amounts (3.2% -6.9%). Significant seasonal variations were observed in content all classes of lipids. The PUFAs prevailed in total lipids and the content of n-6 PUFAs was higher than n-3 PUFAs on all stages of life with the exception of vegetation period. Monogalactosyldiacylglycerols (MGDG) and digalactosyldiacylglecerols (DGDG) were rich in PUFAs and n-3 PUFAs were dominated among them independently of stages of growth. Saturated fatty acids (SFA) were dominated in sulfoquinovosyldiacylglycerols (SQDG). Triacylglycerols (TAG) and diacylglycerols (DAG) contained many PUFAs, especially n-6 PUFAs. Significant concentration 20:3 n-6 was in the triacylglycerols. The concentration of chlorophylls and carotenoids was increased with the growth and maturation of S. pallidum and reached maximum in period of highest day length and water temperature. The content of pigments decreased with the onset of short days and decreasing water temperatures. Nutritional value and benefit for health of human this alga were evaluated. The n-6/n-3 PUFAs ratio, nutritional quality index (atherogenic and thrombogenic indices, and ratio between hypocholesterolemic and hypercholesterolemic fatty acids) were low, suggesting a high nutritional value of S. pallidum throughout the year.

ABSTRACT-We conducted a first order analysis on the proximate composition (protein, carbohydrate, fat and astaxanthin) of three dominant seaweed species viz. Enteromorpha intestinalis, Ulva lactuca and Catenella repens inhabiting Indian Sundarbans. The study was conducted at three stations (Gosaba, Bali Island and Jharkhali) during premonsoon, monsoon and postmonsoon of 2014-15. The relevant hydrological parameters (surface water temperature, salinity, pH, dissolved oxygen and dissolved nutrients) were monitored simultaneously during the tenure of the work. ANOVA carried out on the observed data reflects pronounced variations of all hydrological parameters except surface water temperature and salinity between stations. Pronounced seasonal variations were observed for all the selected hydrological parameters. In the domain of proximate composition, ANOVA results exhibit pronounced variations between stations and seasons (except carbohydrate in U. lactuca and C. repens between stations and astaxanthin in U. lactuca between seasons).

“…Several researchers reported light metal in particular calcium leaching from Sargassum biomass. [27][28][29] Due to high cation exchange capacity, Sargassum acquires these light metal ions from seawater. [30] It is interesting to note that the light metal leaching from S1 and S4 were approximately same, which confirmed the role played by zeolite is minimal.…”

In this study, in situ hybrid sand filters were designed to remove dissolved and suspended contaminants from eutrophic pond. Currently, there are no attempts made to eradicate dissolved as well as suspended contaminants from eutrophic water system in a single step. Monitoring studies revealed that examined pond contain high chlorophyll-a content (101.8 μg L(-1)), turbidity (39.5 NTU) and total dissolved solids concentration (0.04 g L(-1)). Samples were further exposed to extensive water quality analysis, which include examining physicochemical parameters (pH, conductivity, total dissolved solids, salinity, turbidity and chlorophyll-a), metals (Na, K, Ca, Mg, Al, Fe, Cu, Cd, Pb, Zn, Cr, and Ni) and anions (NO3, NO2, PO4, SO4, Cl, F and Br). To tackle pollutants, filtration system was designed to comprise of several components including fine sand, coarse sand/sorbent mix and gravel from top to bottom loaded in fiberglass tanks. All the filters (activated carbon, Sargassum and zeolite) completely removed algal biomass and showed potential to decrease pH during entire operational period of 20 h at 120 L h(-1). To examine the efficiency of filters in adverse conditions, the pond water was spiked with heavy metals (Cu, Cd, Pb, Zn, Cr, and Ni). Of the different filter systems, Sargassum-loaded filter performed exceedingly well with concentrations of heavy metals never exceeded the Environmental protection agency regulations for freshwater limits during total operational period. The total uptake capacities at the end of the fifth event were 24.9, 20.5, 0.58, 5.2, 0.091 and 2.8 mg/kg for Cr, Ni, Cu, Zn, Cd and Pb, respectively.
