Recombinant bacteria for producing deoxyviolacein and uses thereof

摘要

Recombinant bacteria for producing deoxyviolacein and uses thereof are provided, wherein the recombinant bacteria is obtained by introducing the deoxyviolacein synthesis-related gene cluster into Escherichia coli BL21-CodonPlus (DE3)-RIL or Pseudomonas putida mt-2. The deoxyviolacein synthesis-related gene cluster is obtained by knocking out VioD gene from the violacein synthesis-related gene cluster composed of VioA, VioB, VioC, VioD and VioE, and the nucleotide sequence is as shown in the SEQ ID NO: 1 in the sequence listing. A method for producing deoxyviolacein by fermenting the recombinant bacteria to produce deoxyviolacein by using L-tryptophan as substrate is provided. The method has high efficiency of deoxyviolacein production, the deoxyviolacein produced is convenient to be extracted, and simple to be separated and purified.
