General description
Application
Analysis Note
Appearance (color): red
pH-value (25 °C): 7.0 - 7.4
Growth promotion test in accordance with the current version of DIN EN ISO 11133.
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.
Reference media: Tryptic Soy Agar
Footnote
The designations basic, plus, or prime are added to indicate the quality control level, from basic quality control to standard QC plus to prime for full regulatory compliance.
