The polysaccharide extracts from Pterocl dia tenuis, Laurencia flexilis Setchell var. tro-pica, Ceramium kondoi, Glaiopeltis furcata and Polysiphonia urceolata were investigated. The yield, gel strength, viscosity, gelation and melting temperature, and contents of sulfate and 3,6-anhydro-galactose of polysaccharide were analysed. Infrared and 13C-NMR spectroscopy were used to identify their structures.The results indicated that the polysacchari les from the five red algae species had repeating disaccharide units of agar or masked agar structure. The polysaccharide gel strength from alkali treated (32% NaOH, 30℃, 5 days) L. flexilis var. tropica was high (1%, 424g/ cm2), and that from alkali treated P. tenuis was very high (1%, 697 g/cm2), so these two red algae can be used as raw materials for agar production. The gelation temperature of the polysaccharide from alkaki treated C. kondoi was very low (22.4℃) so C. kondoi can be used to produce agar of low gelation temperature. Polysaccharides extracted from alkali treated G. furcata and P. urceolata showed little gelation ability.

Based on the results of the works on the fermentation of Tremella fuciformis spore polysaccharide in shaking flasks,the further study on the fermentation by the strain TS907.5 was carried out in a 7001-fermen- ters and a 25001-fermenters step by step.The above experiments mainly showed that it was essential to control the concentration of glucose and optimum aeration in the scaling-up of Tremella fuciformis spore polysac- charide fermentation process in order to accumulate more polysaccharide in the broth.Finally,in the 25001-fermenter the accumulated concentra- tion of Tremella fuciformis spore ploysacchride in the broth was 18.79g/1 (the average 12g/1).Meanwhile,the extraction rate of the polysacchride reaches 20.0g/1(the average 18.3g/1)and the quality of the polysaccha- ride powder reaches the enterprise-standards.And then the disscussion about the results of the above experiments was mathematically made.

The IR 13 C-NMR spectra of the alkali-treated products were very similar to that of agarose. So it seems to be suitable to call the former porphyran and to call the later porphyra agar. The results show that P. haitanesis may be used as raw material for agar industuy.
