Ubiquinone-10 is produced by culturing a microorganism belonging to the genus Sporidiobolus or Oosporidium and capable of producing ubiquinone-10, causing the microorganism to accumulate ubiquinone-10 and recovering ubiquinone-10.

Method for producing ubiquinone-10

Deacetoxycephalosporin C can be produced with advantage by fermentation of a microorganism which belongs to the genus Streptomyces, Cephalosporium, Emericellopsis, Paecilomyces, Anixiopsis, Arachnomyces or Spriroidium and is capable of producing deacetoxycephalosporin C. Deacetoxycephalosporin C is a useful antibiotic as such or can be used as a starting material for the production of other various cephalosporin antibiotics.

Production of deacetoxycephalosporin C

D-Ribose is produced by cultivating a strain belonging to the genus Bacillus, which lacks sporulation ability or has high 2-deoxy-D-glucose-oxidizing activity or has both of these two properties and also lacks at least one of transketolase and D-ribulose phosphate 3-epimerase, to cause said strain to elaborate and accumulate a large amount of D-ribose. The thus accumulated D-ribose can be recovered in good yield.
