“…The findings of present experiment coincide well with that of protein and carbohydrate contents reported by Ricketts (1966) who worked with golden brown algae. But lipid was 10-30 folds higher than that of Ricketts (1966). Simple lipids (with chlorophyll) were 0.82% and 0.96% of dry sample-l and sample-2, respectively, while 0.19% and 0.20% on wet weight basis.…”

Biochemical composition of bro\VIl alga Sargassum horneri was investigated by determination of moisture, protein, carbohydrate, ash, simple lipids and glycolipids. Fatty acid composition of simple lipids and glycolipids was determined by gas chromatography. The algal specimens were collected in two different months, January (sample-I) and February (sample-2). Moisture contents were 86.94 and 87.00% in sample-l and sample-2, respectively. Protein, carbohydrate and ash contents were 22.94,19.93 and 32.00% of the dry sample-1, respectively, while the contents of the dry sample-2 were 21.96, 20.81 and 33.58%, respectively. Glycolipids were 1.38 and 1.96% of the dry sample-l and sample-2, respectively, whereas 2.45 and 2.75% when the samples were digested with the abalone Haliatis discus enzyme. Of the glycolipids obtained, MGDG, DGDG and SQDG were nearly 15, 15 and 68%, respectively

“…There were little differences in protein, carbohydrate and ash contents in sample-l and sample-2. Ricketts (1966) reported that protein ranged from 24-46%. lipid 14-48% and carbohydrate 5-57% of various golden bro"\iVIl algae in dry weight basis.…”

“…Generally, carbohydrates such as α/β-glucans are known to be major storage compounds stored during photosynthesis and preferentially utilized as primary energy/carbon sources in the dark in many phytoplankton species, while lipids play a role in slow, degradable carbon storage (Ricketts 1966 ; Handa 1969 ). However, our results demonstrate that β-glucan is not a major energy/carbon storage in E. huxleyi since 14 C-flux into β-glucan for storage was extremely low, and therefore the amount of degradation was also very low (Fig.…”

Quantitative Analysis of Carbon Flow into Photosynthetic Products Functioning as Carbon Storage in the Marine Coccolithophore, Emiliania huxleyi

The bloom-forming coccolithophore Emiliania huxleyi (Haptophyta) is a dominant marine phytoplankton, cells of which are covered with calcareous plates (coccoliths). E. huxleyi produces unique lipids of C37–C40 long-chain ketones (alkenones) with two to four trans-unsaturated bonds, β-glucan (but not α-glucan) and acid polysaccharide (AP) associated with the morphogenesis of CaCO3 crystals in coccoliths. Despite such unique features, there is no detailed information on the patterns of carbon allocation into these compounds. Therefore, we performed quantitative estimation of carbon flow into various macromolecular products by conducting 14C-radiotracer experiments using NaH14CO3 as a substrate. Photosynthetic 14C incorporation into low molecular-mass compounds (LMC), extracellular AP, alkenones, and total lipids except alkenones was estimated to be 35, 13, 17, and 25 % of total 14C fixation in logarithmic growth phase cells and 33, 19, 18, and 18 % in stationary growth phase cells, respectively. However, less than 1 % of 14C was incorporated into β-glucan in both cells. 14C-mannitol occupied ca. 5 % of total fixed 14C as the most dominant LMC product. Levels of all 14C compounds decreased in the dark. Therefore, alkenones and LMC (including mannitol), but not β-glucan, function in carbon/energy storage in E. huxleyi, irrespective of the growth phase. Compared with other algae, the low carbon flux into β-glucan is a unique feature of carbon metabolism in E. huxelyi.Electronic supplementary materialThe online version of this article (doi:10.1007/s10126-015-9632-1) contains supplementary material, which is available to authorized users.

“…Presence of highest carbohydrate content of 56.78 mg/g in the seaweed C. aerea and a minimum of 27.57 mg/g in G. corticata of the current study closely resemble with the previous work carried out in this line. [28] In general, the lipid provides very much level of energy in oxidation process than other biological compounds. They comprise as a storage material for living organisms.…”

ABSTRACT. Proximate composition of the three green seaweeds viz., Chaetomorpha aerea, Enteromorpha intestinalis, Enteromorpha compressa one brown seaweed Dictyota dichotoma and one red seaweed Gracilaria corticata was investigated by determination of protein, carbohydrates, lipid, moisture and ash content. In the present study, the total protein was recarded upper most in E. intestinalis and bare minimum in E. compressa. The maximum carbohydrates recorded in C. aerea and minimum in G. corticata. The lipid content was acquired upper limit in E. compressa and least in C. aerea. The ash and moisture content in following of 5 different seaweeds are as follows: 7.45mg/g, 3.91mg/g were recorded in the C. aerea, 8.52mg/g, 3.42mg/g in the E. intestinalis, 8.58mg/g, 3.75mg/g in the E. compressa, 9.47mg/g, 4.23mg/g in the D. dichotoma and 6.95mg/g, 3.98mg/g in G. corticata. The proximate composition of 5 different seaweed species exhibited high nutritional value for human consumption.
