Water quality assessment of the Langat River, Selangor, Malaysia using the natural algal periphyton community and laboratory bioassays of two Chlorella species

The physico-chemical conditions in 10 sampling stations off the headwaters of the Langat River, Selangor, Malaysia were studied. Monitoring was done twice a month from June to December 1980. Changes in water quality were observed downstream. A total of 35 taxa of periphyton in four main divisions of algae were identified. The decrease in the number of species in downstream stations could be due to changes in the river rather than to chemical pollution. Two species of Chlorella , namely, C. pyrenoidosa and C. vulgaris , were grown in filtered river water obtained from the different sampling stations to assess their growth responses. Results suggest that pollution in the Langat River was caused mainly by heavy siltation rather than chemical pollutants.

This paper presents a historical account of the development of algal taxonomy in the Philippines, from its early beginnings in 1800 to the present, with emphasis on marine forms.
Marine algal taxonomists in the country are urged to shift emphasis from the classical morphologic approach to the chemotaxonomic and cytologic method in attempts at resolving the classification and phylogeny of important marine groups such as the polymorphic and economically important Caulerpa, Ulva, Codium, Sargassum , and Gracilaria . Chemotaxonomy has close affinity with the morphological approach, hence is given priority over cytology with the use of the scanning electron microscope.

A great variety of seaweeds grow abundantly along the 81,000-km coastline of the 13,000 islands comprising the Indonesian archipelago. However, it is only recently that the economic importance of seaweeds has really been appreciated. At present, seaweeds collected in Indonesia are mainly used for food supplement, domestic agar manufacture, and for export. Because of the increasing demands for the carrageenan-containing seaweed, mass cultures have been undertaken in both experimental and production sites established in many parts of the country. These efforts are expected to increase the annual volume of exports from 2000 to 6000 mt. The paper reviews the state and problems of seaweed utilization, development, and farming efforts in Indonesia.

Dogma Jr., Ireneo J.; Trono Jr., Gavino C.; Tabbada, R. A.
A discussion is presented on the commercial production of algae in mass culture conditions as a source of single-cell protein. Particular reference is made to the food situation in the Philippines, and research conducted by the Institute of Science and Technology regarding protein-rich algal strains suitable for commercial culture.
