Biodiversity Analysis of Carrageenan Producing Seaweeds From the Balinese Coastal Area of Indonesia

Forty strains of carrageenan producing algae were collected form Lembongan and Nusa Penida islands of Indonesia. Genomic DNA from the samples was extracted, and mitochondrial Cox2-3 genes were cloned and sequenced. The classifications of the samples were determined by constructing a phylogentic tree. The result indicated that all the samples were divided into two different species: Eucheuma denticulatum and Kappaphycus striatum. This study adds to our knowledge of biodiversity of the carrageenan producing seaweeds from Indonesia.
