Abstract
An efficient method of extraction for carotenoids in Rhodotorula glutinis KCTC 7989 was developed. Major carotenoids produced were identified as torularhodin of 61.7%, $\beta$-carotene of 28.8%, and torulene of 9.5%. HCI treatment, as a pretreatment on cell, was necessary to carry out together with thermal treatment unlike DMSO pretreatment. The choice of solvent had an important effect on the composition of carotenoids extracted: benzene and chloroform were effective for the extraction of torularhodin, especially. However, diethyl ether was most effective for the extraction of total carotenoids. Freeze dried type cells showed high efficiency value for the extraction of carotenoids, in compared with dried and wet type cells.
