Abstrak/Abstract |
Microalgae are microscopic photosynthetic organisms found in marine and freshwater
environments. This organism is a eukaryotic group of polyphiletic and very diverse. This study
investigated the biochemical composition of Chlorella Sp. and Spirulina Sp. isolated from Glagah
coastal water (Yogyakarta, Indoneisa) as a potential nutritional supplement for human health.
Microalgae culture was carried out at Biotechnology Laboratory, Faculty of Biology, Universitas
Gadjah Mada, Yogyakarta, Indonesia and analyzed for biochemical composition conducted at
Integrated Research and Testing Laboratory UGM) using several methods: AAS for metal
analysis (Pb, Cu, Fe, Mg, Zn, and Hg), GC and UV spectrophotometer for fatty acid profiles
analysis (LA (Lenolenic acid), EA (Eicosatrienoic acid), Arachidonic Acid, Linoleic Acid, Oleic
Acid, Eicosenoic Acid, EPA, DHA, and Omega (6 and 9)), Alkaloids, Steroids, Tanin and Saponin.
The resulting nutritional value, based on biochemical composition, is compared to commercial
Spirulina sp. and Chlorella sp. products. Microalga Glagah strain shows that biochemical content
is largely similar to commercial products, and in some cases superior. Meanwhile, organic
nutritional properties are relatively higher against commercially valued products, with a rich
biochemical profile of Fe, some nutritious polyunsaturated fats (such as Linolenic Acid,
Arachidonic Acid, Omega 6, and Omega 9). These findings suggest that Glagah strain microalgae
are considered to have great potential as a multi-nutritional human health supplement. |
