Growth Profile And Lipid Composition Of Locally Isolated Benthic Diatom Amphora Subacutiuscula (Schoeman, 1972) Under Different Cultivation Conditions

Diatom bentik adalah pengeluar EPA semulajadi, namun demikian jumlah EPA yang dihasilkan adalah rendah dalam persekitaran semula jadi, terutamanya penderitaan daripada pembatasan resapan cahaya. Kekurangan ini telah mendorong penyelidikan untuk memperbaiki kandungan EPA dalam biojisim yang dikul...
