Phycocolloid ecology of underutilized economic red algae
Carrageenan and agar are structural cell wall components of several red algae. Both are sulfated polysaccharides, which can form gels in milk or water-based solutions. Of the two, carrageenan has a greater ash content and requires somewhat higher concentrations to gel; it is used widely in the food, cosmetic and pharmaceutical industries (Levring et al. 1969). Agar is employed principally as a bacteriological culture medium in hospitals and laboratories, but also has a wide variety of other applications (Chapman 1970).
