Document Type and Number:
WIPO Patent Application WO/2023/283821
Kind Code:
A1
Abstract:
Disclosed are a preparation method for and an application of lactic acid. The preparation method for lactic acid comprises the following steps: (1) inoculating a lactic acid-producing strain, after being activated, into a seed culture medium for culture to obtain a seed solution; and (2) mixing the seed solution obtained by step (1) with supplemental glucose, a fermentation culture medium, a trace element and amino acid for fermentation to obtain lactic acid. According to the preparation method for lactic acid provided in the present application, the operation steps are simple, the purity of the lactic acid is high, and the content of a byproduct 2-hydroxy acid-based compound is low.
