Tissue age as a factor affecting carrageenan quantity and quality in farmed Kappaphycus striatum (Schmitz) Doty ex Silva

Optimization of Carrageenan Extraction Process From Seaweed

“…[16] [17] However, the values for native carrageenan gel strength were higher than those found [18] [19] , used alkaline extraction but no salt in sample preparation, results in obtained weak gels (<50 g.cm -2) of carrageenan extracted from Eucheuma isiforme from different regions. Other workers [20][ 21] also obtained values close to those found for native carrageenan. When they analyzed the extract of the other seaweeds which produce carrageenan (Kappaphycus striatumpredominantly κ-carrageenan and Chondrus crispus -producer of carrageenan hybrid κ/ι, respectively).…”

Formation of carrageenan-CaCO 3 bioactive membranes

“…Peaks also emerged in the 925-935 cm −1 region for all the samples, due to 3,6-anhydro-D-galactose [18]. These bands represented the total sulfate in carrageenans [19]. Although band overlap made assignment of the presence of CaCO 3 in the membranes difficult, some changes in band intensity and shape stood out.…”

Effect of soda ash industry effluent on agarophytes, alginophytes and carrageenophyte of west coast of India

“…It is well known that the yield and quality of phyco-colloids produced in marine farms vary not only with the seaweed strain under cultivation but with a series of biological and environmental parameters such as age of plants, light, nutrients, temperature and salinity, amongst others [14][15][16][17][18]. Abiotic factors such as depth (light), salinity, substratum, nutrients, water motion, sedimentation and pollution affect the structure and distribution of algal communities at a local scale [19][20][21][22][23][24][25].…”
