Twenty-two strains of Rhodotorula were examined as to the optical nature of theircarotenoid pigments extracted with acetone and petroleum ether.The cells cultivated in two kinds of media were employed for the extraction of the pigments. One was a synthetic medium reported by WICKERHAM (1952) and the other was potato yeast extract. Each strain was incubated in 50 ml each of the above two media at 28℃ on a rotary shaker for four days. With the cells harvested from the latter medium, the pigment extracts of eighteen red strains were found to exhibit an absorption maximum at 48 mμ, while those of three yellow strains at 450 mμ. The pigment extract of the other yellowish orange one, Rht. glutinis var. aurantiaca, showed an absorp-maximum at 470 mμ.
