Lactate production of engineered Synechocystis PCC6803. Comparison of WT, ldhD-lldP, ldhDc-lldP, ldhDnARSdR-lldP, ldhDARSdR-lldP. Synechocystis grew for 7 days(OD=1), then L-Rhamose(1g/L) was added. After induced 72 hours, lactate concentration in culture supernatant has shown above.Obviously ,we can see the engineer sphaerocystis produced more lactate. | Lactate production of engineered Synechocystis PCC6803.

RBS-ldhDC-FLAG-lldP-his tag
Show the expression of the protein.
Characterization
We add FLAG-tag and His-tag to help us to detect whether the protein has been expressed or not.
Fluorescence image
To make sure that we get the target gene, we did the detection of fluorescence microscopy .And here is the result.Needless to see that the gene expressed well. The fluorescence of YFP is much more brighter than negative control.Therefore ,to some extant the expression is was successful.
SDS page
There were nearly 0.2g bacteria used to testify the expression of lldP. After affinity chromatography, the protein was electrophoresed through SDS-PAGE. As the red box shows, lldP can be seen . Comparing to wild type, lldP is expressed in Synechocystis sp. PCC 6803.
lactate detect
Lactate production of engineered Synechocystis PCC6803. Comparison of WT, ldhD-lldP, ldhDc-lldP, ldhDnARSdR-lldP, ldhDARSdR-lldP. Synechocystis grew for 7 days(OD=1), then L-Rhamose(1g/L) was added. After induced 72 hours, lactate concentration in culture supernatant has shown above.Obviously ,we can see the engineer sphaerocystis produced more lactate.
