, cultivation in the sea, more turbulent habitats, at various depths, with and without commercial fertilizer supply. Initially, the effectiveness of a given cultivation strategy was based on the survival and growth of the fronds, here termed ‘bio-assay’ mariculture. Ambient seawater temperature, nutrient availability, hydro

Chinese phycologists have conducted research on sporeling and field cultivation of . for many years. Trials have been made using: (1) raft cultivation based on vegetative propogation of thallus fragments, (2) cul

General principles of on-shore cultivation of seaweeds: effects of light on production,e on on-shore cultivation systems, none of these has yet proved to be economically viable on a sustained basis; nevertheless, such cultivation systems offer the potential for productivities greater than can be achieved in other systems. In on-shore systems, factors other than light can be controlled

Chemical structure and physico-chemical properties of agar,iscussed. These advances are essentially the result of better separation techniques of the heterogeneous family of polysaccharides known as agar, the use of nuclear magnetic resonance spectroscopy, the use of agarases and, particularly, the use of combinations of the three approaches. Although physi

Agars from Chilean Gelidiaceae, hydrocolloids correspond to those of an agar-type polysaccharide. The percentages of 6-.-methyl-galactose and of pyruvic acid ranged between 5.7-6.2% and 0.42-0.54%, respectively. The gel melting and gelation temperatures of ., . and . agars were determined. A correlation between 6-.-methylgalactos

Agar and agarose biotechnological applications,he preparation of solid microbiological media. The numerous techniques available for the purification of agar affect the characteristics of bacterial-grade agar. The availability of agarose, that fraction of agar with the lowest possible charge, has enhanced the utilzation of this phycocolloid. The
