In the original publication [1], there was an error in Figure 2 as published. In Figure 2, due to too many pictures in the data processing process, some pictures were repeated.
The corrected Figure 2 appears below.
Figure 2.
The D-alanine demand identification of recombinant L. casei strain pPG-Alr-COE/ΔAlr W56. The recombinant strains pPG-Alr-COE/ΔAlr W56, pPG-T7g10-PPT/ΔAlr W56, and ΔAlr W56 were streaked on de Man-Rogosa-Sharpe (MRS) plates to detect the demand of D-alanine. “+” and “−” represent MRS plates with and without D-alanine, respectively; Alr-COE/ΔAlr W56, pPG-Alr-COE/ΔAlr W56; PPT/ΔAlr W56, pPG-T7g10-PPT/ΔAlr W56.
The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
