Query: NC_008686:1960034 Paracoccus denitrificans PD1222 chromosome 1, complete sequence
Lineage: Paracoccus denitrificans; Paracoccus; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: This organism is commonly found in soil and sewage sludge. This organism is able to survive in both aerobic and anaerobic environments due to its ability to use both oxygen and nitrogenous oxides making it a popular model organism for the study of electron transfer and and energy conservation.
Subject: NC_010125:2884762 Gluconacetobacter diazotrophicus PAl 5, complete genome
Lineage: Gluconacetobacter diazotrophicus; Gluconacetobacter; Acetobacteraceae; Rhodospirillales; Proteobacteria; Bacteria
General Information: Gluconacetobacter diazotrophicus strain PAL5 (ATCC 49037) was isolated from sugarcane roots in Brazil and will be used for comparative analysis. Nitrogen-fixing plant symbiont. This acid-tolerant organism is endophytic and colonizes internal plant tissues, establishing a symbiotic relationship with its host. This bacterium has been found in sugarcane, coffee, rice, tea, and other plants. The nitrogen-fixation systems of the bacterium provide the plant with essential nitrogenous compounds while the plant provides a protected environment for the bacterium to grow in. Nitrogen-fixation is important for sugarcane production, and this organism can fix nitrogen even in the presence of nitrate.
