Query: NC_014837:387868 Pantoea sp. At-9b chromosome, complete genome Lineage: Pantoea; Pantoea; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria General Information: Environment: Host; Temp: Mesophile. Pantoea sp. (strain At-9b) is a cellulose-degrading Gram-negative bacterium isolated from the fungus gardens of Atta cephalotes leaf-cutter ants. Pantoea sp. has the capacity to degrade cellulose, and thus may play a role as cellulose-degrading symbionts in the gardens of leaf-cutter ants.

General Information: This organism was first isolated from the soil in Vineland, New Jersey, although it is found worldwide. It is a large obligate aerobe that has one of the highest respiratory rates of any organism. Azotobacter vinelandii also produces a number of unusual nitrogenases which allow it to fix atmospheric nitrogen to ammonia, a compound it can then use as a nitrogen source. It protects the oxygen-sensitive nitrogenase enzymes through its high respiratory rate, which sequesters the nitrogenase complexes in an anoxic environment. This organism has a number of unusual characteristics. Under extreme environmental conditions, the cell will produce a cyst that is resistant to dessication and is surrounded by two capsular polysaccharide layers. This organism produces two industrially important polysaccharides, poly-beta-hydroxybutyrate (PHB) and alginate. PHB is a thermoplastic biopolymer, and alginate is used in the food industry. Alginate is also used by the pathogen Pseudomonas aeruginosa to infect the lungs of cystic fibrosis patients.
