The fatty acids of 18 strains of Bordetella avium, 3 strains of Alcaligenes faecalis, 5 strains of Bordetella bronchiseptica, and 12 strains of a B. avium-like organism were examined by gas chromatography-mass spectrometry. The presence of a significant amount of the acid 2-OH C14:0 characterized B. avium and the B. avium-like organism. B. avium and the B. avium-like organism differed in their ...

polyhydroxyalkanoates (phas) are bioplastics derived from renewable resources such as vegetable oils, corn starch, or microbes. the polyhydroxybutyrate (phb) is a short-chain-length pha, and the most important bioplastic produced by certain microorganisms in the presence of excess carbon sources. in this study batch cultivation of alcaligenes eutrophus with the aim of increasing phb production ...

The purification and initial characterization of arsenite oxidase from Alcaligenes faecalis are described. The enzyme consists of a monomer of 85 kDa containing one molybdenum, five or six irons, and inorganic sulfide. In the presence of denaturants arsenite oxidase releases a fluorescent material with spectral properties identical to the pterin cofactor released by the hydroxylase class of mol...
