    摘要： The present invention relates to a method for producing L-methionine using a bio-synthesis process and a specific enzymatic process. More particularly, the present invention relates to a method for producing L-methionine with high yield by enzyme conversion reaction from L-methionine precursor in the presence of methyl mercaptan (CH3SH). The process of the present invention enables selective production of L-methionine which may be used in various fields of industry, such as feed- and food-additives, as raw material for medical supplies, pharmaceutical drugs, and the like.

    摘要： The present disclosure relates to a microorganism producing L-lysine and a method for producing L-lysine by using the same. More specifically, the present disclosure relates to a microorganism of the genus Corynebacterium , which is modified such that the activity of a protein involved in cell wall hydrolysis is inactivated in comparison with the endogenous activity thereof; and a method for producing L-lysine using the same.

    摘要： A method of preparing a low-molecular lignin derivative comprises the step of: preparing lignin by hydrolyzing lignocellulosic biomass with an acid; preparing a first mixture by mixing 100 parts by weight of the lignin and 500 parts or more by weight of a phenolic compound; preparing a second mixture by mixing the first mixture with a solvent including the hydrophobic polar solvent; and recovering a low-molecular lignin derivative from the second mixture.
