Inoculum on reference medium (Bacillus cereus ATCC 11778 (WDCM 00001)):
Colony count (Bacillus cereus ATCC 11778 (WDCM 00001)):
Recovery on test medium (Bacillus cereus ATCC 11778 (WDCM 00001)): ≥ 50 %
Growth (Bacillus subtilis ATCC 6633 (WDCM 00003)): no limit
Growth (Escherichia coli ATCC 8739 (WDCM 00012)): total inhibition
Growth (Escherichia coli ATCC 25922 (WDCM 00013)): total inhibition
Colonies (Bacillus cereus ATCC 11778 (WDCM 00001)): pink colonies with precipitation halo
Colonies (Bacillus subtilis ATCC 6633 (WDCM 00003)): yellow colonies without precipitation halo
Incubation:
B.cereus 24 ± 3 to 44 ± 4 hours at 30 ± 1 °C
other teststrains 44 ± 4 hours at 30 ± 1 °C
A recovery rate of 50 % is equivalent to a productivity value of 0.5.
The indicated colony counts result from the sum of a triple determination.
