TSB medium was made using our own recipe. TSB* and TSB 2.0. TSB* is from Wikipedia and TSB 2.0 is based on literature, what amounts of glucose and NaCl are beneficial for biofilm growth. Test difference between TSB* and TSB 2.0 with With four different strains: JH642, PY79, 3610 comI and -3610 comI ΔabrB on 4 different carriers: nylon, W2, W4 and W6. Experiment was performed in triplo. OD measurement
JH 0.85
PY 0.67
3610 1.53
ΔabrB 0.40
All ODs were diluted until 1.5 mL with an OD of 0.22 was obtained. The samples were diluted with water.
An OD of 0.22 was used to make comparing with the 128 plates experiment easier.
