Pertumbuhan, Kadar Pigmen dan Aktivitas Antioksidan Spirulina platensis pada Kultur dengan Perbedaan Warna Pencahayaan Leds
Antioksidan diperlukan tubuh untuk melindungi kesehatan kulit kita. Salah satu sumber antioksidan adalah mikroalga Spirulina sp.

期刊介绍: The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
