  • Process for producing coenzyme Q.sub.10
    Patent number: 4245048
    Abstract: The invention provides a process for producing coenzyme Q.sub.10 by cultivating a novel microorganism JY-155 which belongs to the genus Trichosporon (FERM-P4650, ATCC 20566) which we discovered, in a culture medium containing sulfite waste liquor as the carbon source. The microbial cells form and accumulate coenzyme Q.sub.10. These cells are then recovered from the culture and processed to obtain the coenzyme Q.sub.10 as a compound or to obtain it in usable form while still associated with at least some of the cell material.
