| titleOfInvention | Method for preparing 2-pyrrolidone using biomass |
| abstract | The present invention comprises the steps of (a) culturing a microorganism containing glutamate decarboxylase as a whole-cell catalyst in a medium containing glutamic acid or glutamate to prepare 4-aminobutyl acid; (b) obtaining the 4-aminobutyl acid from the medium by filtration; And (c) relates to a method for producing 2-pyrrolidone using biomass comprising the step of converting the 4-aminobutyl acid to 2-pyrrolidone. The present invention provides a series of processes for preparing 2-pyrrolidone from glutamic acid or glutamate using biomass. According to the present invention, 2-pyrrolidone is produced in high yield using 4-aminobutyl acid directly using microorganisms as whole cells, and preferably directly using 4-aminobutyl acid which is not subjected to complicated purification processes such as crystallization. It can be manufactured economically. According to the present invention, 2-pyrrolidone can be produced in large quantities with high yield and low production cost. The present invention is suitable for mass production on an industrial scale through the simplification of the process for the production of 2-pyrrolidone. |
