Volatiles from the Psychrotolerant Bacterium Chryseobacterium polytrichastri

The flavobacterium Chryseobacterium polytrichastri was investigated for its volatile profile by use of a closed‐loop stripping apparatus (CLSA) and subsequent GC‐MS analysis. The analyses revealed a rich headspace extract with 71 identified compounds. Compound identification was based on a comparison to library mass spectra for known compounds and on a synthesis of authentic standards for unknowns. Important classes were phenylethyl amides and a series of corresponding imines and pyrroles.
Over 70 volatile organic compounds have been identified in a headspace extract from C. polytrichastri. The extract was particularly rich in nitrogen‐containing natural products, many of which were structurally derived from 2‐phenylethylamine. Several compounds are new natural products, their suggested structures are based on the observed mass spectral fragmentation, confirmed by synthesis of reference substances.
