Abstract
Lytic enzyme produced by Bacillus circulans A1.383-2 was proved to be able to hydrolyze the cell wall of Phaffia rhodozyma effectively and make astaxanthin be extractable by the uniform design. When the hydrolysis temperature and pH to modify the yeast-walls were 37°C and 5.0, respectively, and 33ml lytic enzyme (1603.8u.g-1 dry yeast) was added, over 98% of the astaxanthin could be extracted within 16.5h.
