E.coli Bacterial Growth Curve Assay Protocol
Materials
-1 brain-heart infusion (BHI) broth culture of 5h E.coli -1 tube with 5.0 ml BHI broth -Spectrophotometric tubes -Plastic disposable pipettes -Spectrophotometer at 590 nm -37°C water bath
Procedures
1. Add approximately 6 drops of the BHI into a spectrophotometer tube; this will be the blank tube.
2. Add about 6 drops of BHI into a spectrophotometer tube and and another 6 drops of the E.coli broth into the same tube; this will be experimental tube.
3. Read the blank tube on the spectrophotometer and blank the system at 590 nm.
4. Read the experimental tube at 590 nm and record the data.
5. Incubate the experimental tube for 20 minutes at 37°C.
6. Once the incubation is complete, read the experimental tube on the spectrophotometer and record the data.
7. Repeat steps 5-6 as many times as desired to get a good growth curve.
8. Graph the data accordingly.
