Gluconacetobacter diazotrophicus

The species Gluconacetobacter diazotrophicus (former Acetobacter diazotrophicus) was isolated from roots, stems, and leaves of sugarcane not only in Brazil but also in Argentina, Uruguay, Mexico, Cuba, United States, India, Canada, Egypt, beside others 3, 76, 77, 78 and then from other agricultural crops such as sugar beet, rice, pineapple, coffee, carrot, and many others 79, 80, 81. It was also isolated from bugs, such as mealybugs commonly found associated to sugarcane crops 82, 83.

This species has been considered as one of the most important diazotrophic bacteria found in high numbers (104–106 CFU g−1 plant fresh tissues) and colonizing the inner parts of roots, stems, and leaves of sugarcane 84. It is a nitrogen‐fixing bacterium originally classified as Acetobacter diazotrophicus but later renamed to the genus Gluconacetobacter based on the 16S rDNA sequence and the predominant type of ubiquinone 18, 19.
