Article Abstract:
The properties of amine oxidases from Klebsiella oxytoca and their distribution in bacteria grown on primary amines were described. The bacteria K. oxytoca have used primary amines as a carbon and energy source. Amine oxidase was employed by K. oxytoca, E. coli and methylotroph Arthrobacter P1 while amine dehydrogenase was utilized by pseudomonads and Paracoccus versutus. Results showed that a single amine oxidase is involved in the conversion of all amines used. K. oxytoca was found to produce a copper-quinoprotein oxidase similar to Enterobacteriaceae.

Article Abstract:
Identification of the bacteria causing urinary tract infection by whole-organism DNA fingerprinting can be done using analytical spectroscopies of high intrinsic dimensionality coupled with chemometrics. Clinical bacterial isolates were examined using pyrolysis mass spectrometry, infrared spectroscopy and dispersive Raman microscopy. Results reveal that the causative agent can be identified using a combination of the above analytical methods and artificial neural networks.

Article Abstract:
Competition of three predominant ruminal celluloytic bacteria is discussed as it occurs in the presence or absence of noncellulolytic bacteria. The three are Fibrobacter succinogens S85, Ruminococcus flavefaciens FD-1 and Ruminococcus albus 7. Data show that cellulolytic bacteria interactions, though complex, may be changed further by noncellulolytic species.
