Conteúdo: | Chromobacterium violaceum is a Gram-negative bac-terium, abundant in a variety of ecosystems in tropical and subtropical regions, including the water and borders of the Negro River, a major component of the Amazon Basin. As a free-living microorganism, C. violaceum is exposed to a series of variable conditions, such as differ-ent sources and abundance of nutrients, changes in temperature and pH, toxic compounds and UV rays. These variations, and the wide range of enviranments, require great adaptability and strong protective systems. The complete genome sequencing of this bacterium has revealed an enormous number and variety of ORFs associated with altemative path-ways for energy generation, transpon-related proteins, signal transduc-tion, cell motility, secretion, and secondary metabolism. Additionally, the limited availability of iran in most environments can be overcome by iron-chelating compounds, iron-storage proteins, and by several proteins related to iron metabolism in the C. violaceum genome.
