Carpospore germination and early stages of development in Gracilaria edulis (Gmelin) Silva and Gracilaria rubra Chang et Xia (Gracilariales, Rhodophyta)
(San Carlos Publications, University of San Carlos, 1993)
Carpospore germination and early stages of development in Gracilaria edulis and Gracilaria rubra of the Philippines are described for the first time. Both species follow the "Dumontia type" or the immediate discal type of ...
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 ...
The effects of different stocking densities and some abiotic factors on cage culture of Gracilaria sp. (Rhodophyta, Gigartinales)
(Walter de Gruyter, 1992)
Specific growth rates (% day<sup>-1</sup>) and production rates (g m<sup>-2</sup> day<sup>-1</sup>) of Gracilaria sp. reared in net cages on a bamboo floating raft from March 1989 to February 1990 were determined at different ...
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 ...
Effects of gel depth and gel surface area on agar gel strength
(San Carlos Publications, University of San Carlos, 1993)
Agar is a high priced phycocolloid extracted from red seaweeds (Rhodophyta) called agarophytes. It is a mixture of polysaccharides whose basic monomer is galactose (Armisen and Galatas 1987). Agar has many uses in the food ...
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 ...
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 ...
