The invention belongs to the technical field of enzyme engineering, and relates to a D-amino acid oxidase mutant and application thereof. According to the mutant, one or more of S3R, N54I, T56N, F58K, Q98R and M213S are mutated in D-amino acid oxidase of an amino acid sequence as shown in SEQ ID NO. 1. Compared with wild type D-amino acid oxidase, the mutant has the advantage that the fermentation activity and the conversion rate are obviously improved. The activity of the D-glufosinate ammonium is improved by 5400 times at most, the conversion rate reaches 49.8% (the theoretical value is 50%), and the D-glufosinate ammonium is almost completely converted. According to the mutant, the use cost of the enzyme is remarkably reduced, the reaction time is shortened, the generation rate of the L-glufosinate-ammonium precursor 2-carbonyl-4-[hydroxyl (methyl) phosphonyl] butyric acid is increased, and the mutant is more suitable for industrial application.
