Poster: Microbial survival in compressed gases under fast decompression to normal atmospheric conditions

This scientific poster reviews numerous scientific literature related to microbial survival under a broad range of environmental pressure conditions, and the resilience of microorganisms under variable compression and decompression environments.

Through a detailed analysis of previously published literature, microorganisms demonstrate the capability of surviving the relatively moderate environmental pressure found in compressed gases used in the pharmaceutical industry, and the decompression to normal atmospheric conditions during the sampling of these gases.

Moreover, compressed gases for pharmaceutical purposes are always decompressed before being in contact with the product. Therefore, sampling after decompression is closer to the real usage of the compressed gas.
