CAROTENOIDS 



In the case of Sporobolomyces roseus and Sp. salmonicolor^ 

 Lederer^2,3 6 could find no p-carotene, but only torulene and torul- 

 arhodin. However, in some new Sporobolomyces species (^-carotene 

 occurs to the extent of 23 [j.g. per g., the corresponding values for 

 torulene and torularhodin being 92 and 41-7 (xg./g. 



Apparently in the Rhodotorulaceae the carotenoids are not secreted 

 in the fat globules but are dissolved in the pericapsular fat.** The 

 qualitative distribution of carotenoids in fungi is set out in Table 16.
