THE POTENTIAL OF HETEROTROPHIC MICROALGAE (Schizochytrium sp.) AS A SOURCE OF DHA

Abstract

Docosahexanoic acid (DHA) is commercially obtained from marine fish. W ith an increasing human population, the supplies of DHA are still not sufficient to meet the world's need of DHA as food supplement. The objective of this review is to discuss Schizochytrium sp., one of microalgae which is rich in DHA, as one of the best candidate as producer of sustainable and affordable DHA. Heterotrophic microalgae, especially genus Schizochytrium, produces omega-3 fatty acids up to 40% of total unsaturated fatty acids. Cultivation of the microalgae is easy as it does not require sunlight as source of energy. Previous publication reported that several local strains of Schizochytrium have been isolated from mangrove area in Indonesia. W e expect that those strains can be cultivated in mass production as producer of DHA.Keywords: docosahexanoic acids, fatty acids, Schizochytrium sp. ABSTRAK Docosahexanoic acid (DHA) komersial sebagian besar diperoleh dari ikan laut. Dengan meningkatnya populasi penduduk dunia, sumber ini tidak akan mencukupi permintaan dari masyarakat terhadap DHA sebagai salah satu makanan kesehatan. Tujuan dari review ini adalah untuk mendiskusikan Schizochytrium sebagai salah satu mikroalga yang kaya DHA, sebagai kandidat mikroalga yang mampu memproduksi DHA secara berkelanjutan dan terjangkau. Jenis mikroalga yang bersifat heterotrof terutama genus Schizochytrium mampu menghasilkan asam lemak omega 3 mencapai 40% dari total asam lemak tak jenuhnya. Kultivasi mikroalga ini juga lebih mudah karena tidak membutuhkan sinar matahari sebagai sumber energinya. Publikasi sebelumnya menunjukkan bahwa beberapa strain lokal telah di isolasi dari daerah mangrove di Indonesia. Kami berharap strain tersebut bisa dikembangkan ke produksi DHA secara masal.Kata Kunci: asam docosaheksanoat, asam lemak, Schizochytrium sp.

Heterologous expression of phytase in Schizochytrium sp. as a fortified feed additive for the Livestock industry

“…This study measured the activity of the partially purified phytase to eliminate any potential effects of crude biomass on the assay. Similar reports were also observed by Hakim (2013) and Padmavathi et al (2018).…”

Optimizing Docosahexaenoic Acid (DHA) Production by Schizochytrium sp. Grown on Waste Glycerol

“…The present experiments are part of larger pioneer research efforts on the use of waste organic substrates to grow heterotrophic microalgae Schizochytrium sp. for industrial purposes [47,48]. As these microalgae are able to grow on a variety of carbon sources, they may reasonably be grown on waste glycerol [49].…”
