#1 Selection / Swimming - 7th week

Swimming assay with trypton agar

Experiment:
A variety of agar conditions were tested: 1) 1% trypton, 0.3% agar, 0.5% NaCl; 2) 0.5% trypton, 0.3%, 0.5% NaCl; 3) like 1, but with additionally 0.5% glcose; 4) like 2), but with additionally 0.5% glucose. The swimming assay was performed as mentioned in methods.
Observations & results:
All plates w/o glucose showed strong swimming over night. Therefore, glucose could be considered to be taxis-inhbiting.

Comined swimming assays

Experiment:
The strains from the previos experiments were combined on a single plate (several distinct drops on the same plate) to compare their swimming ability directly.
