GLUCANOACETOBACTER INTRODUCTION Glucanoacetobacter is a genuine in the phylum proto bacteria. It is like rod shape and circular ends. It can be classified as gram negative bacterium. The bacterium is known for stimulating plant growth and being tolerant to acetic acid with one to three lateral flagella and known to be found on sugar cane. Gluconacetobacter diazotrophicus was discovered in Brazil by Bladimir A Cavalcante and Johannna/Dobereiner. Domain: Bacteria Phylum: Proteobacteria Class :Alphaproteobacteria Order : Rhodospirillales Family: Acetobacteraceae Genus:Gluconacetobacter Species:G.diazotrophicus CHARACTERISTICS Originally found in Alagoas, Brazil, Gluconacetobacter diazotrophicus is a bacterium that has several interesting features and aspects which are important to note. The bacterium was first discovered by Vladimir A. Cavalcante and Johanna Dobereiner while analyzing sugarcane in Brazil. Gluconacetobacter diazotrophicus is a part of the Acetobacteraceae family and started out with the name, Saccharibacter nitrocaptans, however, the bacterium is renamed as Acetobacter diazotrophicus because the bacterium is found to belong with bacteria that are able to tolerate acetic acid. Again, the bacterium’s name was changed to Gluconacetobacter diazotrophicus when its taxonomic position was resolved using 16s ribosomal RNA analysis. In addition to being a part of the Acetobacter family, Gluconacetobacter azotrophicus belongs to the Proteobacteria phylum, the Alphaprotebacteria class, and the Gluconacetobacter genus while being a part of the Rhodosprillales order. Other nitrogen-fixing species in this same genus include Gluconacetobacter azotocaptans and Gluconacetobacter johannae. Gluconacetobacter diazotrophicus cells are shaped like rods, have ends that are circular or round, and have anywhere from one to three flagella that are lateral. Based on these descriptions of the cell, Gluconacetobacter diazotrophicus can be classified with the bacillus genus. The cells be viewed as darkish brown or orange colonies under a microscope addition, the cells are aerobic which describes their need of oxygen. Because the bacterium is found on sugar cane when first discovered, as explained prior, and reacts strongly to high amounts of sugar, Gram Negative is the correct classification for Gluconacetobacter diazotrophicus. In addition to sugarcane, G. diazotrophicus has been found in different plants like coffee tree and pineapple. Gluconacetobacter diazotrophicus is also known for nitrogen fixation. .
