===<strong>Expression of indigoidine in Corynebacterium glutamicum</strong>===
 +
We have successfully expressed bpsA in Corynebacterium glutamicum. As shown below, the right conical flask shows the fermentation results after introducing empty PEKEX2 into the C.glutamicum, whereas the left conical flask shows the fermentation results of indigoidine production after introducing bpsA plasmid into C.glutamicum. Obviously, the left one expresses bpsA successfully with fully blue in the fermentation broth.

the composite part is used to express the bpsA gene.

Construction of the bpsA gene and tac inducible promoter to control the production of the blue-pigment indigoidine synthetase. The composite part is inserted into C.glutamicum in plasmid, resulting in the successful biosynthesis of indigodine pigment.

We amplified two bpsA fragments then transformed recombinant vector into DH5α E.coli strain and Corynebacterium glutamicum.

Expression of indigoidine in Corynebacterium glutamicum

We have successfully expressed bpsA in Corynebacterium glutamicum. As shown below, the right conical flask shows the fermentation results after introducing empty PEKEX2 into the C.glutamicum, whereas the left conical flask shows the fermentation results of indigoidine production after introducing bpsA plasmid into C.glutamicum. Obviously, the left one expresses bpsA successfully with fully blue in the fermentation broth.

We used DMSO to suspend C.glutamicum, and then sonicated the bacteria to break them apart. After centrifugation, we collected the supernatant to measure the absorption peak, and the absorption peak was about 590nm, which proved that it was indeed indigoidine.

Below is a diagram of SDS-PAGE of Corynebacterium glutamicum. From left to right, the first lane is the whole cell lysate of C. glutamicum, the second lane is the whole cell lysate after introduction of the plasmid, the third lane is the supernatant of wild-type C. glutamicum, and the fourth lane is the supernatant after introduction of the plasmid. It indicates that bpsA successfully expressed indigoidine after introduction of the plasmid.

Direct Dyeing

We stained the bacterial cellulose membranes directly with C. glutamicum cultures to test the binding capacity of microbial dye to bacterial cellulose membrane.
