Figure 3From: Acetaldehyde and hexanaldehyde from cultured white cellsChromatogram of acetaldehyde from the bioreactor headspace of cells from 4-, 24- and 48-h incubations and ambient lab air. For clarity, media chromatograms are not shown (see Fig 2 for associated media responses and standard deviations). Acetaldehyde was not present in appreciable concentrations in any of the identified sources of contamination such as Teflon vials, plastic culture ware and room air samples.Back to article page
