Abstract
|
|
|
|
Ubiquitous photosynthetic microalgae, Haematococcus lacustris, is believed to be the organism which can accumulate the highest levels of astaxanthin cultured under the stress conditions. In the present study our research aim is to establish the best condition for the immobilization of astaxanthin onto a matrix, chitosan. In order to optimize the condition for the immobilization of astaxanthin, cells were crushed using a mortar and extracted using ice-cold deionized water with small contents of ethanol. Cell extractants were immobilized by adsorption in physically onto chitosan, a natural polymer, for the immobilization of astaxanthin. A complex of chitosan and astaxanthin can be used as high-value of unique biomaterials in various fields such as in medical science, pharmaceutical, food, food or feed additives.
