The envelope containing Bionova® BT40 Spore Strip is specifically designed for the monitoring of Ethylene Oxide (EO) sterilization processes or for Dry Heat sterilization processes.
Spore strips should be incubated in Bionova® MC1020-2 growth medium tube or in appropriate growth medium for Bacillus atrophaeus ATCC® 9372 growth.
If the sterilization process was not successful, Bionova® MC1030-2 growth medium will turn to yellow after incubation at 37±2 ºC, thus indicating the existence of living Bacillus atrophaeus spores on the strip.
If the sterilization process was successful, MC1020-2 Medium will remain its original color. A final readout should therefore be performed after 48 hours of growth medium incubation at 37±2 ºC.
For conventional culture medium like TSB, incubation for 7 days at 37 ºC is recommended.
