THE EFFECT OF ARGENTUM AND CADMIUM TOWARDS ASTAXANTHIN CONTENT IN GREEN ALGAE, HAEMATOCOCCUS PLUVIALIS

- Haematococcus pluvialis is a kind of microalgae with high potential in the production of astaxanthin- a secondary carotenoid with high commercial values. However, the mass production of astaxanthin is still not possible due to the low yield of astaxanthin obtained from this alga. The present st...
