A Gram-stain-negative, rod-shaped, motile bacterium, designated AER10T, was isolated from the roots of Ammodendron bifolium collected from Takeermohuer desert in Xinjiang Uygur Autonomous Region, northwestern China. Growth was found to occur from 10 to 45 °C, at pH 5.0-9.0, and could tolerate up to 10 % (w/v) NaCl. 16S rRNA gene sequence result indicated that the strain AER10T belongs to the ge...

Achromobacter xylosoxidans is frequently isolated from the respiratory secretions of cystic fibrosis (CF) patients, but identification with biochemical tests is unreliable. We describe fluorescence in situ hybridization assays for the rapid identification of Achromobacter xylosoxidans and Alcaligenes faecalis. Both assays showed high sensitivities and high specificities with a collection of 155...

To determine the incidence of bacteremia in healthy adults, blood cultures were obtained from 240 patients who had no demonstrable foci of infection. Five patients (2.1%) had positive blood cultures. Staphylococcus epidermidis was isolated from four patients and Alcaligenes faecalis from one. In each of these patients, the organism isolated probably represented contamination rather than bactere...

1,3-Propanediol (1,3-PD) is an important chemical product which can be used to produce polyesters, polyether, and polyurethanes. In the process of conversion of glycerol to 1,3-PD by Clostridium large number of byproducts (butyric, acetic and lactic acid) are generated in the fermentation medium. The aim of this work was to isolate bacteria strains capable of the utilization of these byproducts...

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 ...

Alcaligenes fecalis BDB4 was isolated from crude oil-contaminated soil in India. The genome sequence of A. faecalis BDB4 revealed the presence of important genes required for polyaromatic hydrocarbon (PAH) metabolism and other associated functions, such as chemotaxis, membrane transport, and biofilm formation, giving insight into the complete PAH mineralization potential of this bacterium.

D-Aminoacylase from Alcaligenes xylosoxydans subsp. xylosoxydans A-6 (Alcaligenes A-6) was strongly inactivated by diethylpyrocarbonate (DEPC). An H67N mutant was barely active, with a kcat/Km 6.3 x 10(4) times lower than that of the recombinant wild-type enzyme, while the H67I mutant lost detectable activity. The H67N mutant had almost constant Km, but greatly decreased kcat. These results sug...
