Production of acetoin and 2,3-BD isomers by B. licheniformis WX-02 and the gdh mutant strains. WX-02 wild-type strain, WX-02Δgdh the mutant strain with gdh gene knocked out from the genome of WX-02, WX-02Δgdh/PHY-gdh the mutant strain with gdh gene complemented to the knock-out strain WX-02Δgdh. The cells were grown under shake-flask culture conditions for 24 h. Data are means of three replicates, and error bars show standard deviations
