Effect of Time and Temperature in Assessing Microbial Contamination on Flat Surfaces

摘要

Experiments were performed to investigate incubation time and temperature effects for Rodac agar contact plates applied to bench top surfaces in industrial clean rooms. For studies of general microbial levels, incubation at 32 C for 43 hr was found suitable for Rodac plates containing 15.5 ± 0.1 ml of Trypticase Soy Agar.
