Produção primária de Pterocladia capillacea (Gelidiaceae - Rhodophyta)

Unusual structures in the polysaccharides from the red seaweed Pterocladiella capillacea (Gelidiaceae, Gelidiales).

Sequential extraction of tetrasporic Pterocladiella capillacea with water at room temperature and then at 50 degrees C led to the isolation of two products that were each fractionated with cetrimide to give a soluble fraction and a precipitate. The precipitates were then subjected to fractional solubilization in solutions of increasing sodium chloride concentration. The whole treatment yielded ...

Preparation of Agar-Agar from the Red Seaweed Pterocladia capillacea off the Coast of Alexandria, Egypt.

The effect of different treatments on the quality of agar produced from Pterocladia has been studied, and the conditions for the production of material of good quality have been standardized. In the modified process, sun-bleached seaweed was washed well in water, soaked for 24 h, and then ground to a pulp and rinsed again in water. The pulp was then extracted with water (weed-to-water ratio, 1:...

Gelidium omanense sp. nov. (Gelidiaceae, Rhodophyta) from the Sultanate of Oman

A new species of the red algal genus Gelidium, G. omanense M.J. Wynne, is described from the Sultanate of Oman, northern Arabian Sea. This species is a very commonly occurring eulittoral seaweed on the Omani coast, essentially one of the dominant species during the summertime southwest monsoon on exposed rocky shores.
