Algal polysaccharide production

摘要

Selected polysaccharides are produced from algal plant tissue by (a) separating vegetative parts or spores into (i) gametophytes, or (ii) tetrasporophytes; (b) vegetatively propagating the separated plant material; (c) harvesting the resulting plant growth; and (d) recovering the desired polysaccharides from the harvested material. Different specific polysaccharides (e.g., kappa- or lambda-carrageenan) have been found to be produced by (i) or (ii) above. This method avoids difficult post-harvest separations and is amenable to controlled vegetative propagation of the separated plant material under optimum conditions.
