Query: NC_017259:25400 Buchnera aphidicola str. Ua (Uroleucon ambrosiae) chromosome, Lineage: Buchnera aphidicola; Buchnera; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria General Information: It is believed that the Buchnera provide the essential nutrients the host lacks. Besides a nutritional co-dependence, due to a co-existence of millions of years, Buchnera have lost the ability to produce cell surface components such as lipopolysaccharides. This makes for an obligate endosymbiont relationship between host and Buchnera. Buchnera are prokaryotic cells which belong to the gamma-Proteobacteria, closely related to the Enterobacteriaceae family. Phylogenetic studies using 16S rRNA indicate that the symbiotic relationship was established around 200-250 million years ago. Since Buchnera are closely related to Escherichia coli and Haemophilus influenzae, comparative genomic studies can shed light on the evolutionary mechanisms of intracellular endosymbiosis as well as the different underlying molecular basis between organisms with parasitic behavior and symbionts.

General Information: This strain is a marine gamma-proteobacterium that was isolated from decaying Spartina alterniflora, a salt marsh cord grass, in the Chesapeake Bay, USA. Saccharophagus degradans 2-40 has been used to produce ethanol from plant material and may be useful for the production bioethanol. Bacterium able to degrade complex carbohydrates. Saccharophagus degradans is capable of degrading insoluble complex carbohydrates through the collective action of enzyme complexes found on its cell surfaces, utilizing the degradation products as a carbon source. This organism may be useful in bioremediation. The degradative enzymes this organism produces are typically exoenzymes that are collected and organized into large surface complexes termed cellulosomes.
