Plate 10 µL B. subtilis 3610 ComI overnight culture (OD: 2,28 (600nm) after 22h growth) on different carrier materials on LB agar and MSgg agar plates. MSgg was prepared according to protocol.
Carrier materials using LB agar as a medium
Nylon positive charge (Boeringer, 1269299)
Nytran Plus 0.45 µm (Schleicher en Schuell, AH0495-1)
PVDF (Rocke, 03010040001)
Nitrocellulose 0.2 µm (invitrogen, LC2000)
Nylon 0.45 µm (Merck Milipore, HNWP04700)
Nitrocellulose 0.025 µm (Merck Milipore, VSWP02500)
Control (no carrier)
Carrier materials using MSgg agar as a medium
Nytran Plus 0.45 µm (Schleicher en Schuell, AH0495-1)
PVDF (Rocke, 03010040001)
Nitrocellulose 0.2µm (invitrogen, LC2000)
Nylon 0.45 µm (Merck Milipore, HNWP04700)
Nitrocellulose 0.025µm ( Merck Milipore, VSWP02500)
Control (no carrier)
All plates with carrier and bacteria were put in the incubator at 30°C.

After 24 hours, the biofilm growth was checked.

After 120 hours, the biofilm growth was checked. Biofilm growth thrives better on MSgg as can be seen on the images below. After 120 hours there is a clear difference visible between the LB and MSgg conditions. Furthermore, Nitrocellulose 0.2µM shows an nice and even distribution of biofilm and PVDF doesn't show biofilm growth at all on the MSgg plate.
