Detection of non-host viable contaminants in Pichia pastoris cultures and fermentation broths.

Abstract excerpt

The ability to detect viable contaminants in cultures propagated from the original host-expression system ensures that the integrity and purity of seed banks, fermentation broths, and ultimately the final product are continually controlled and maintained. The method developed to detect such agents must be selective for a broad spectrum of microbes, which may be present at very low levels, while discriminating...
