Biochemical tests for identification of medical bacteria, 3rd ed. Lippincott, Williams, and Wilkins, Philadelphia, PA. 7.

Achromobacter and Alcaligenes spp. are opportunistic human pathogens causing sporadic cases of pneumonia, septicemia, peritonitis, and urinary tract and other infections. 36–39 Achromobacter xylosoxidans and Alcaligenes faecalis are the most common isolates and agents of disease, but little is known about factors promoting virulence.

Misidentification might lead to unnecessary tests and inappropriate treatments. . Alcaligenes faecalis (A. faecalis) . VITEK 2 system misinterpreted the important biochemical characteristic results for distinguishing A. baumanni from A. faecalis as negative before the biochemical reactions were fully completed. Although the exact .

Characteristics. Alcaligenes are Gram-negative, aerobic bacteria although some strains are capable of anaerobic respiration in the presence of nitrite or nitrate. They are catalase and oxidase positive. They are short rods or cocci with dimensions 0.5–1.0 μm in diameter by 0.5–2.6 μm in length and the cells occur singly.

Although standard biochemical tests used for the identification of Alcaligenes spp. revealed only minor differences, the oxidative low-peptone technique clearly differentiated between Alcaligenes-like bacteria of avian origin and Alcaligenes spp. reference strains. .

alcaligenes faecalis biochemical tests bacteria alcaligenes faecalis. Biogenic souring and microbial-influenced corrosion is a common scenario in petroleum reservoir. The serious threat normally comes from sulfate-reducing bacteria (SRB). Alcaligenes faecalis was tested in this study for the ability to inhibit the growth of SRB.Arunkumar et al. / Research in Biotechnology, 3(4): 19-27, 2012 22 negative, motile bacillus based on microscopy and tentatively identified as genus Alcaligenes by biochemical tests (Table.1).The eighth edition of Bergey’s Manual of Determinative Bacteriology (Buchanan and Gibbons, 1974) lists the genus Alcaligenes under “Genera of Uncertain Affiliation”. Although Alcaligenes faecalis was first isolated from stale beer by Petruschky (1889) and subsequently described by many others, its taxonomy is still uncertain and controversial. .
