Gracilaria studies at SEAFDEC/AQD
(Network of Aquaculture Centres in Asia-Pacific, 1996)
Research in seaweed from 1988–1994 focused on the agar producing Gracilaria. Studies in the following areas were also conducted: inventory of the seaweed resources; production ecology; farming systems; and agar characterisation. ...
Agar production from Gracilariopsis heteroclada (Gracilariales, Rhodophyta) grown at different salinity levels
(Walter de Gruyter, 1994)
Gracilariopsis heteroclada grown in fiber glass tanks at four salinity levels was treated with three different concentrations of aqueous NaOH. Yield, gel strength, gelling and melting temperatures of the extracted agar ...
Agar yield, gel strength and sulfate content in Gracilariopsis heteroclada farmed in brackishwater canals
(Society of Israeli Aquaculture and Marine Biotechnology, 1996)
This paper aimed at determining the optimum NaOH pretreatment strength and duration and the monthly variations in gel strength, agar yield and sulfate content of agar from Gracilariopsis heteroclada (Zhang et Xia) farmed ...
Improvised filter unit for agar extraction/filtration
(San Carlos Publications, University of San Carlos, 1993)
Agar is a high-priced phycocolloid usually extracted from red seaweeds (Rhodophyta). It has many uses in the food and pharmaceutical industry (Chapman 1970, Armisen and Galatas 1987). Worldwide production of agar has reached ...
Effect of stocking density and nutrients on the growth and agar gel of Gracilariopsis bailinae (Gracilariales, Rhodophyta)
(San Carlos Publications, University of San Carlos, 1995)
The effect of additional nutrients and varying stocking densities (500, 1000, and 2000 g m<sup>-2</sup>) on the growth and physical properties of Gracilariopsis bailinae was determined. Growth was significantly higher (L ...
Evaluation of agar from three species of Gracilaria from Panay and Guimaras islands
(San Carlos Publications, University of San Carlos, 1993)
Agar from three species of Gracilaria, G. changii G. coronopifolia, and Gracilariopsis heteroclada, collected form Panay and Guimaras islands was evaluated. Each species was pretreated with NaOH solution before extraction. ...
Rheological properties of agar from Gracilariopsis heteroclada (Zhang et Xia) Zhang et Xia (Gracilariales, Rhodophyta) treated with powdered commercial lime and aqueous alkaline solution
(Walter de Gruyter, 1992)
Rheological properties were measured for 1.5% agar gels from Gracilariopsis heteroclada pre-treated with powdered commercial lime (CaCO<sub>3</sub>) during sun drying, and a combination of two alkaline solutions during ...
The interactive effect of some environmental factors on the growth, agar yield and quality of Gracilariopsis bailinae (Zhang et Xia) cultured in tanks
(Walter de Gruyter, 1997)
The single and interactive effects of light and temperature, salinity, and urea enrichment on the growth and agar yield and quality of Gracilariopsis bailinae were determined under indoor and outdoor tank conditions. Culture ...
