Zusammenfassung:The invention relates to the technical field of microbial engineering, in particular to a lactobacillus mutant strain HCYJ-06 and application thereof. The strain is obtained through mutagenesis screening by taking lactobacillus with the preservation number of CICC (China General Microbiological Culture Collection Center) 23474 as a starting strain, and the preservation number is CGMCC NO.26643; the preservation date is February 21, 2023; the preservation unit is China General Microbiological Culture Collection Center (CGMCC); the preservation address is No.3, Yard 1, Beichen West Road, Chaoyang District, Beijing; the lactobacillus mutant strain HCYJ-06 is named as lactobacillus (Lactobacillus sp) in taxonomy, and the lactobacillus mutant strain HCYJ-06 is named as Lactobacillus sp. After the lactobacillus mutant strain HCYJ-06 is cultured in a 5L fermentation tank, the gamma-aminobutyric acid conversion amount of the lactobacillus mutant strain HCYJ-06 can reach 413g/L-420g/L, and the strain has a relatively
