Thirty-seven species of seaweeds including 10 Chlorophyta, 13 Phaeophyta, and 14 Rhodophyta collected from the coast of Nagasaki Prefecture, Japan, were screened for algicidal activity against the red-tide phytoplankton Heterosigma akashiwo. The green alga Ulva fasciata (Ulvaceae, Chlorophyta) showed the strongest algicidal activity among the seaweeds tested. Bioassay-guided fractionation of th...

Marine seaweeds that belong to Chlorophyta, Rhodophyta, and Phaeophyta groups are reported biosynthesize metal nanoparticles. The morphology the stability of nanoparticles obtained from for biomedical environmental applications equivalent in most aspects other “green” methodologies. ability algae accumulate metals reduce ions make them a superior contender biosynthesis hence they called bio-nan...

Pantai Kelapa Panyuran memiliki sumber daya alam yang melimpah, salah satunya adalah makroalga. Makroalga merupakan biologi kelautan berperan penting dalam ekosistem perairan. Penelitian ini bertujuan untuk mendeskripsikan keanekaragaman makroalga di Kelapa, sehingga diharapkan dapat memberikan gambaran tentang Kelapa. Metode digunakan observasi, penelusuran sepanjang jalur pantai, dan dokument...
