Yield and chemical characterization of Solieria filiformis carrageenan extracted from lipid extraction residues (Products 3a–b).

Product	Carrageenan Yield (%)	Carbohydrates (%)	Sulfate Groups (%)	3,6 Anhydro-Galactose (%)
Product 3a	17.09 ± 2.39 a	34.34 ± 1.88 a	18.15 ± 1.87 a	18.57 ± 2.01 a
Product 3b	29.67 ± 4.14 b	28.79 ± 1.02 b	34.91 ± 3.65 b	7.43 ± 0.77 b
Carrageenan from direct extraction	25.55 ± 2.6 b	22.47 ± 1.16 c	47.66 ± 10.4 b	16.11 ± 0.88 a

Different superscripts indicate significant differences (p < 0.05). Percentage of carrageenan expressed as a function of the initial biomass. Carbohydrates, sulfate and 3,6 anhydro-galactose content are expressed as percentage of carrageenan yield. a and b correspond to conditions denatured and non-denatured enzyme, respectively.
