METHOD FOR PREPARING SUCCINIC ACID USING SUCROSE AS A CARBON SOURCE

摘要

The present invention relates to a method for preparing succinic acid, which comprises culturing a succinic acid-producing microorganism in a medium containing sucrose as a carbon source, and more particularly, a method for preparing succinic acid, which comprises culturing a succinic acid-producing microorganism under batch or fed-batch culture conditions in a medium containing sucrose as a carbon source at a high concentration. According to the present invention, when inexpensive sucrose, whose price corresponds to 28.9% of glucose price, is used as a carbon source, microorganisms have improved resistance against organic acids including succinic acid compared to the case using other carbon sources such as glucose to significantly increase succinic acid productivity as well as final succinic acid concentration, thus making it possible to reduce costs required for separating and purifying succinic acid.
