(Springer, 2022-03)
The phytochemical constituents, total phenolic and flavonoid contents, antioxidant and antimicrobial activities of the ethanolic extract of the marine green alga Ulva pertusa collected from floating fish net cages off the ...
Sargassum studies in Currimao, Ilocos Norte, Northern Philippines I. Seasonal variations in the biomass of Sargassum carpophyllum J. Agardh, Sargassum ilicifolium (Turner) C. Agardh and Sargassum siliquosum J. Agardh (Phaeophyta, Sargassaceae)
(Walter de Gruyter, 1999)
Three species of Sargassum (S. carpophyllum, S. ilicifolium and S. siliquosum were collected each month for a period of one year from the inter- and subtidal zones of Pangil, Currimao, Ilocos Norte, The Philippines. Average ...
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 ...
Carrageenan properties and proximate composition of three morphotypes of Kappaphycus alvarezii Doty (Gigartinales, Rhodophyta) grown at two depths
(Walter de Gruyter, 1995)
Three morphotypes (brown, green and red) of Kappaphycus alvarezii grown at two depths were evaluated for carrageenan properties and proximate composition. The green morphotype was significantly different from the brown and ...
Tank culture of Gracilaria heteroclada (Zhang et Xia)
(College of Agriculture and Central Experiment Station, University of the Philippines Los Baños, 2003)
Culture conditions in tanks were manipulated to improve the growth and agar quality of Gracilaria heteroclada Zhang et Xia. Specific growth rates during culture ranged from -0.51% to 1.40% and gel strength of agar from 439 ...
Growing the reproductive cells (carpospores) of the seaweed, Kappaphycus striatum, in the laboratory until outplanting in the field and maturation to tetrasporophyte
(Springer Verlag, 2010)
Carposporophytes of the seaweed, Kappaphycus striatum, from the wild were made to shed spores in the laboratory and grown in multi-step culture method until they reached maturity. For each succeeding transfer onto increasingly ...
Assessment of some agarophytes from the coastal areas of Iloilo, Philippines. II. Seasonal variations in the agar quality of Gracilaria changii, Gracilaria manilaensis and Gracilariopsis bailinae (Gracilariales, Rhodophyta)
(Walter de Gruyter, 1996)
Three species of agarophytes (Gracilaria changii, G. manilaensis and Gracilariopsis bailinae) collected along the mud flats of Iloilo were investigated to determine the monthly variation in agar yield (%), gel strength (g ...
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 ...
