Serial dilutions of the cell suspension to be tested were prepared and 10 μL of each dilution were inoculated to a
96 wells plate containing 180 μL of LB media. For each dilution 10 replicates were prepared. Plates were incubated
at 37˚C for 24 hours and cell concentration was determined using the Reed and Muench Method [16].
Spores were counted using the same method, but the plates were heated to 80˚C for 20 minutes before incubation.
