Incubation Time and Conditions of Active or Passive Air SCDA Plates

Hey guys,

In our procedure the SCDA plates of active and passive air samples are incubated for 5 days in 32,5 C temp. incubators.

But our consultant told that it must be 3 days in 32,5 C (for bacterial growth) and than replace 22,5 C for 5 days (for fungal growth) more.

I agree that idea but i couldnt find any guide which tells the real story. What is the real incubation time, incubation order etc.

Thanks for your replies.

Incubate 2 days at 32.5 C and remaining 3 days at 22.5 C.
