Acidovorax facilis is an aerobic, chemoorganotrophic bacterium used as a soil inoculant in agriculture and horticulture.
Members of A. facilis are generally 1.0-5.0 μm long and 0.2-0.7 μm wide. [1] Under a microscope, they appear as straight to slightly curved rods that occurs singly or in short chains. A. facilis are motile via a single flagellum at one end of the bacterium. They are negative by Gram stain and positive by the oxidase test. When grown on nutrient agar, they form unpigmented colonies. [1] They grow in the presence of oxygen. [1]
A. facilis has been used in agriculture and horticulture as a soil additive to improve plant growth. [2] Additionally, a nitrilase enzyme from A. facilis has been engineered into E. coli for the commercial production of 3-hydroxyvaleric acid. [3]
A. facilis was originally isolated from lawn soil in the United States by Albert Schatz and Carlton Bovell in 1950 and named Hydrogenomas facilis. [1] [4] In 1969, the genus Hydrogenomonas was abandoned and H. facilis was transferred to the genus Pseudomonas . [1] [5] Eventually, Pseudomonas was determined to contain several genera of bacteria, and so in 1990 Pseudomonas facilis, Pseudomonas delafieldii , and several other strains of Pseudomonas and Alcaligenes were transferred to the new genus Acidovorax .
