| Popis: | Studies carried out to breakdown the yield and Fourier-Transform Infrared (FTIR) spectral properties of polysaccharide from Corallina elongata (J.Ellis & Solander), Liagora mannarensis (V.Krishnamurthy & Sundararajan) and Portieria hornemannii (Lyngbye). Carrageenan yield in the range of 16.4 to 24.2% in fresh algae than 14.2 to 23.8% defatted algae was recorded. Spent biomass in the range of 62.0 to 72.0% in fresh algae than 61.2–70.4% defatted algae was recorded. Total sugar, reducing sugar and sulphate were maximum in P. hornemannii (Lyngbye) and minimum in C. elongata (J.Ellis & Solander) having fresh algae carrageenan compared to the defatted algae carrageenan. FTIR spectroscopy study shows that the carrageenan extracted from fresh and defatted C. elongata (J.Ellis & Solander) have both kappa and iota type carrageenan. Fresh and defatted carrageenan from L. mannarensis (V.Krishnamurthy & Sundararajan) and P. hornemannii (Lyngbye) have kappa, lamda and iota type carrageenan. |
