Pyrolysis mass spectrometry as a method for the classification, identification and selection of actinomycetes.

Pilot experiments were designed to determine the potential of Curie-point pyrolysis mass spectrometry (PyMS) in the classification, identification and typing of industrially significant actinomycetes, and for the detection of target and novel actinomycetes needed for pharmacological screening programmes. The results indicate that the method is of value for the separation of actinomycetes at and below the species level, in the detection and circumscription of novel actinomycetes, and for the detection of identical and duplicated strains. There is also evidence that the pyrolysis system will permit the identification of target actinomycetes directly from selective isolation plates. PyMS is one of the methods that should be used to generate polyphasic taxonomies of actinomycete genera.
