Yields and gel strengths of agar from cystocarpic and tetrasporic plants of Gradlaria verrucosa (Fiorideophyceae)
Yield, gel strength and chemical composition of agar extracts were analyzed from several species of Gracilaria collected from Guam, and Saipan in Micronesia and from Taiwan. Highest agar yields (to 71%) were obtained from the Guam species Gracilaria edulis with mild alkaline pretreatment (1% NaOH for 30 min.)Highest gel strengths (to 340 g cm~2) were obtained from agar extracts of G. lichenoides from Saipan after a relatively strong alkakine pretreatment of 5% NaOH for 90 min. Sulfate, pyruvate'and 3,6-anhydrogalactose contents of the agars ranged from 2.5 to 5.3, 0.07 to 0.16 and 26.5 to 44.0 percent, respectively. Specific viscosities of the agars ranged from 2.0 to 4.3 and agar gelling temperatures from 25° to 44 °C. Introduction The world demand for agar has increased rapidly in recent years (Moss 1978, Doty 1979), and presently, the agar-containing seaweeds are in short supply. Since approximately 60% of the world's present production of agar is derived from species of the red-algal genus Gracilaria, interest has been recently generated in examination of additional species for gels suitable for commercial use (Oza 1978, Kim and Henriquez 1978, Deboer 1978, Matsuhashi and Hayashi 1972, Abbott 1980, Whyte and Englar 1980, 1981, Whyte et ai
