Growth properties of dehydrated ICR settle plates used in passive air monitoring

Settle plates provide continuous environmental monitoring of microorganisms in the volume of collected air. The formulation of the chosen culture media should promote the growth of a wide range of microorganisms. This application note investigates the growth properties of ICR settle plates with and without neutralizers. Using this method, the detection of environmental microorganisms could be compared between pre-dried and fresh plates without re-humidifying the dehydrated plates.
