Characteristics Of "Nanowires" Conductor Of Electric Current On The Ability Of Micro-organism Cells

The phenomenon of "nanowires" that portrayed clearly for the first time successfully observed from the observation of the micro-organism Shewanella oneidensis strain MR-1 which is a type of bacteria similar intangible strands of hair that is enabled to supply power along the panhandle stem strands of hair, things that might seem to play a role Key events in the process of respiration in electron terlontarkannya out away from the cell.

Respiration occurs in the metabolic process in which a number of organisms in the body obtain energy from organic molecules that the process occurs in cells and tissues in the body when energy and QAS CO2 (carbon dioxide) is released and absorbed by the blood to be distributed to the lungs. The phenomenon is often referred to as the characteristic "conductive pili" or "nanowires" that shape the ability of micro-organisms in the cell to conduct electrical charges in the order of metabolic processes. The success of research observations of Shewanella oneidensis strain MR-1 performed by expert Moh El-Naggar biophysics from the University of Southern California published in the scientific journal Proceedings of the National Academy of Sciences October issue of the past. 

Unlike the case in the process of respiration with the activation of substances that the process of diffusion of oxygen through the process of exchange of electrons across the cell membrane; the figure for the group of micro-organisms bacteria Shewanella oneidensis MR-1 in the process of respiration is known capable of delivering energy to pass through some form of solid / solid non-organic "metal oxide" as an electron acceptors. Therefore, the experts believe that another mechanism is needed is a way to distribute the release of electrons out until it reaches far beyond the solid substance of the cell membrane. And for the latest research expert microbiologists one of the characteristics of a suspected the characteristic match thus is "nanowires" that are attached to a number of micro-organism cells. 

In research conducted by Moh El-Naggar et al. Shewanella oneidensis bacteria grow in such a way in a condition to make observed abundant production of nanowires as well as by limiting the presence of such substances metal electron acceptors character. Experiments were then apply an electric voltage scanner devices. Observations indicate the presence of electric currents channeled in this configuration. Similarly, when the panhandle nanowires cells set aside the flow of electric currents disappeared. Research has even managed to perform well for the first time the measurement of the nominal amount of electrical current flowing. 

As for the success of research for the first time with a very clear process of scanning the incident following the phenomenon of nanowires on the amount of electrical currents that occur make it as an important discovery for the study of current applied research microbiologi field. The highest appreciation of the importance of these research findings revealed by research scientist microbiologist colleague, namely: Gemma Reguera from Michigan State University, and Derek Lovley of the University of Massachusetts while append research findings which prove the existence of electric currents of the phenomenon of nanowires in the order of these microorganisms as stunning results
