Week 30
Jorrit
Tested transformation of week 29 on SDS-page with silver staining on the CFE, medium & pellet samples, no chaplains visible.
Transformation B sub.
Inoculated NZ8900 ΔTasA in 10 ml MM, overnight @ 37°C shaker.
1 ml overnight culture NZ8900 ΔTasA in 10 ml fresh MM for 3 hours @ 37°C shaker.
Added approx. 1 µg plasmid E and H in two 2 ml tubes and incubated 30 min @ 37°C shaker.
Diluted in pre warmed TY (300 µl) and put for 45 min @ 37°C shaker.
Plated on LB-agar with antibiotic Cm5/Spec100 and grown @ 37°C (colonies @ 30/7).
Inoculated 4 H colonies and 4 E colonies in 5 ml TY with antibiotics Km5 ,Cm5 and Spec100 and put overnight @ 37°C shaker.
Two -80°C stocks were made of B. sub NZ8900 ΔTasA with pNZ8901_E and B. sub NZ8900 ΔTasA with pNZ8901_H.
Inoculated 4 Greiner tubes with pNZ9801 E6, E2, H1, H3 in 5 ml TY with antibiotic Km5 and Cm5.
10 µl of OD cultures (pNZ9801 E6, E2, H1, H3) was taken and grown , overnight @ 37°C shaker, in 5 ml TY with antibiotic Cm5/Spec100 and Cm5.
Done growth curve with OD- measurement.
Of all measurementperiodes were taken 2 ml samples, spinned down and put supernatant and cell pellet in freezer.

We read and looked up some more articles on biofilm formation models. We found that Professor Van Loosdrecht in Delft knows a lot about this and planned a meeting with him. Joël, Arend, Laura, Djoke
