Rhodosporidium diobovatum 08-225 is an oleaginous marine red yeast, isolated from southern Florida, USA. Its optimal growth temperature is between 25 C and 35 C. R. diobovatum is able to thrive well on a wide-range of substrates, including but not limited to glucose, galactose, sucrose, cellobiose, trehalose, ethanol, and glycerol. Like many other species in the same genus, besides producing lipids up to 70% of its dry cell weight, R. diobovatum is capable of producing carotenoids, such as β-carotene, torularhodin, and torulene in varying concentrations. Based on yet to be published work from our laboratory, R. diobovatum synthesizes β-carotene in the first 24 hours post-inoculation. However, by 48 hours post-inoculation, β-carotene concentrations decrease to below detectable levels, while concentrations of torularhodin increase greatly until 72 hours post-inoculation. Therefore, it appears that the primary carotenoid synthesized by R. diobovatum 08-225 is torularhodin.

 

The Rhodosporidium diobovatum 08-225 genome was not sequenced at JGI, but was provided by Irene Fakankun on Feb 5, 2018 and then annotated using the JGI Annotation Pipeline.
