Query: NC_014228:4360676 Xenorhabdus nematophila ATCC 19061, complete genome
Lineage: Xenorhabdus nematophila; Xenorhabdus; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This genus is a group of insect pathogens which live in a mutualistic relationship with the soil nematode family, Steinernematidae. Free-living, juvenile Steinernema spp. enter insect larvae through the digestive tract. They penetrate the larvae body cavity and release Xenorhabdus spp. into the hemolymph (blood). The bacteria multiply rapidly, killing the larvae, and providing suitable nutrient conditions for the growth and reproduction of the Steinernema spp. The nematode matures and reproduces. The new juveniles reassociate with Xenorhabdus spp. and are released into the soil. Unlike Xenorhabdus bovienii, which is found in different Steinernema spp., Xenorhabdus nematophila is associated specifically with Steinernema carpocapsae and can be used as a model for studying host specificity.
Subject: NC_004349:3938 Shewanella oneidensis MR-1 plasmid pMR-1, complete sequence
Lineage: Shewanella oneidensis; Shewanella; Shewanellaceae; Alteromonadales; Proteobacteria; Bacteria
General Information: This strain was isolated from Oneida lake in New York, USA. Potential bioremediation organism. This genus includes species that inhabit a wide range of environments and are capable of utilizing a wide variety of electron acceptors during anaerobic respiration including some insoluble metal oxides while using very few carbon sources such as lactate or acetate. This group of organisms have been studied extensively for their electron transport systems. This organism is a facultative anaerobe that is capable of using a wide variety of terminal electron acceptors during anaerobic respiration which may make it valuable for bioremediation. Since the bacteria can reduce chromium and uranium from the liquid phase to form insoluble compounds, they may be used to eliminate these two environmental pollutants from water.
