Comprehensive study of phycobiliproteins and sulfated polysaccharides from the red alga Ahnfeltiopsis flabelliformis

Successive extraction of phycobiliproteins (PBP) by two methods (0.1 M phosphate buffer and 1.5% NaNO 3 solution) and polysaccharides from reproductive (cystocarps) and sterile red alga A. flabelliformis was performed. The yield of phycoerythrin (PE) was twice as great for extraction by NaNO 3 than...

Description
Summary:Successive extraction of phycobiliproteins (PBP) by two methods (0.1 M phosphate buffer and 1.5% NaNO 3 solution) and polysaccharides from reproductive (cystocarps) and sterile red alga A. flabelliformis was performed. The yield of phycoerythrin (PE) was twice as great for extraction by NaNO 3 than by phosphate buffer. The yield of polysaccharides was 1.6 times greater for successive extraction than without preliminary extraction of PBP from the alga. The polysaccharide content in sterile plants was 1.5 times less than in alga with cystocarps regardless of the PBP extraction method. According to IR spectral data, the polysaccharide from sterile plants was κ-carrageenan; from alga with cystocarps, κ,ι-carrageenan.
