The envelope containing Bionova® BT50 Spore Strip is

specifically designed to control steam 121 ºC to 134 ºC

(Steam) and formaldehyde (Form) sterilization processes.

Spore strips should be incubated in Bionova® MC20 or

MC1020 growth medium tube or in appropiate growth medium

for Geobacillus stearothermophilus ATCC 7953 growth. If the

sterilization process was not successful, MC20 or MC1020

growth medium will turn to yellow after incubation @ 60±2 ºC,

thus indicating the existence of living Geobacillus

stearothermophilus spores on the strips.

If the sterilization process was successful, MC20 or MC1020

indicating medium will remain its original color. A final readout

should therefore be performed after 24 hours of growth

medium incubation @ 60±2 ºC for steam sterilization

processes control, or 48 hours@ 60±2 ºC for formaldehyde

sterilization processes control.
