Differentiation of selected Enterobacteriaceae by pyrolysis-gas-liquid chromatography.
Pyrolysis-gas-liquid chromatography was used to differentiate selected species of Enterobacteriaceae. Individual cultures of Salmonella typhi, Hafnia alvei, and Proteus vulgaris, and 12 strains of Yersinia enterocolitica were grown in nutrient broth. After harvest and lyophilization, the bacterial samples were pyrolyzed at 900 degrees C, and their volatile fractions were separated on a 50-m cap...
متن کاملEffect of different growth conditions on the discrimination of three bacteria by pyrolysis gas-liquid chromatography.
High-resolution pyrolysis gas-liquid chromatography was applied to three bacteria (Escherichia coli NCTC 9001, Pseudomonas putida (NCIB 9494, and Staphylococcus aureus NCTC 8532) grown under a variety of conditions. Changing the culture medium drastically altered the quantitative aspects of the pyrograms of all three organisms, but the effects of culture time and incubation temperature were les...
متن کاملDifferentiation and characterization of Klebsiella pneumoniae strains by pyrolysis-gas-liquid chromatography-mass spectrometry.
Nine coded duplicate strains of capsular nontypable Klebsiella pneumoniae were analyzed by pyrolysis-gas-liquid chromatography-mass spectrometry. All duplicate strains were correctly matched, and individual strains, including seven nontypable strains, were clearly distinguishable from one another. The addition of mass spectrometry to the analysis has aided the process of identification and has ...
متن کاملDetermination of sulfonylureas and metabolites by pyrolysis gas chromatography.
Various sulfonylurea derivatives are widely used to treat some types of diabetes. Although thousands of different compounds have been shown to possess some hypoglycemic activity (1), only a few are used therapeutically. The dose required to achieve an effective plasma concentration of sulfonylurea varies from person to person and even from time to time in the same person (2, 3). Some of the pro...
متن کاملField Detection and Identification of a Bioaerosol Suite by Pyrolysis-gas Chromatography-ion Mobility Spectrometry
Improvements were made to a pyrolysis-gas chromatography-ion mobility spectrometry (Py-GC-IMS) stand-alone biodetector to provide more pyrolyzate compound information to the IMS detector module. Biological aerosols were disseminated at DRES, Alberta, Canada and the Py-GC-IMS was tested for its ability to detect the biological aerosols. Forty-two trials were conducted and a simple area calculati...
