摘要

The present invention relates to a method for producing el-ribose based on el-arabinose, and more specifically, to produce an el-ribose by culturing a first microorganism in which an el-ribose production pathway is introduced from arabinose in a medium containing arabinose. Making a step; After removing the first microorganism from the culture medium, inoculating and incubating the second microorganism into which the L-ribulose metabolic pathway was introduced, consuming the L-arabinose and the L-ribulose, and then producing the resulting L-ribose Recovering. The method of producing el-ribose according to the present invention removes all sugars except for el-ribose in metabolism, so that it is possible to produce high-purity el-ribose from fermented products, and the produced ribose is various L-forms. It is useful because it can be usefully used in the manufacture of medicines as a starting material for the synthesis of pharmaceutical products per sugar nucleic acid.
