3. Description and significance

The bacteria are aerobic anoxygenic phototrophs which use the sulfur derivatives as electron donor and oxygen as electron acceptor. This bacterium is found in the nutrient rich coastal salt seawater. This bacterium as other bacteria in the family gives the smooth red orange color because of its large amount of caroteniods. In the family, this bacterium is similar to others in the form of having no pore on its outer membrane and the bacteria is a gram negative. One of the important aspect is that this family bacteria can not move since they are non motile. Besides the important of the bacteria in recycling the inorganic and the organic compounds, this particular bacterium can also resist the effect of the tellurite and also be able to reduce the compound. This is important for the cleaning up of the environment because the tellurite is also toxic to the other organism including the humans. That ability is similar to the Erythromicrobium. Therefore it is important to sequence the genome of these bacteria in order to compare to the genome of the erythromicrobium. The sequenced genome will help us in understanding the structure of the protein that can help the bacteria in fighting and reducing the tellurite. Sequencing the genome may reveal the relationship between the bacterium and the erythromicrobium. And how are they related in the evolution scale.

Erythrobacter litoralis is the marine bacteria that can give the color of smooth red-orange. This bacterium can be found at the floor of the ocean or in nutrient coastal seawater. One can find this bacterium at the Sargasso Sea. This bacterium is useful in its function of recycling the organic matters. Also the bacteria can use some of the inorganic matter as carbon source. It is important to sequence the genome of this bacterium for its ability to resist the tellurite which is a toxic to the bacteria and other organism including the human. Not only the bacterium is able to resist the tellurite, the bacteria can also reduce the tellurite in order to help the movement of the electron. live at not high pressure environment. Because it. The genome of the bacteria can help scientist to understand more about other pathogen bacteria because of their close relationship. The study of the bacteria genome can explain the LOV- histidine kinase system that is used by other pathogen such as name. also the genome of this bacterium can help in increasing the knowledge of the marine microbes and help the study of the ocean’s biological process and the chemical processes. The study of the genome can help the scientist to see whether there is gene transfer between the cell and the other anaerobic cells. This bacteria is halotolerant aerobic phototroph and a gram negative. This bacterium is distributed in the euphotic zone. This bacterium belongs to the family that can use organic matter as energy source in the aerobic reaction. One of the significant of this family is that members of the family are able to produce bacteriochlorophyll-a which is normal presented in anaerobic organism. The bacterichlrophyll a is used for harvesting light. Yet these bacteria have low level of the photosynthetic unit in cells. Carotenoids of these bacteria which give the microbes their smooth red orange color inhibit light harvesting of the bacteriochlorophyll a. these bacteria can not grow photosynthetically under anaerobic conditions.
