Characteristics of "nanowires" Conductor electrical current capabilities in micro-organism cells.
The phenomenon of "nanowires" are described 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 hair strands are capable of distributing electricity throughout the overhung shaft of hair strands, the things that might seem to play a role key in the process of respiration in the incident electron terlontarkannya out away from the cell.
Respiration occurs in the process of metabolism whereby a number of organisms in the body obtain energy from organic molecules that occur in cells and processes in the body when jarinqan QAS energy and CO2 (carbon dioxide) is released and absorbed by the blood to be distributed to the lungs.
This phenomenon is often referred to as characteristic of "conductive pili" or "nanowires" that shape the ability of micro-organisms in the cell to deliver an electric charge in the order of metabolic processes. The success of research observation of the Shewanella oneidensis strain MR-1 is 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 published in mid October Yl.
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 through the cell membrane, then to group the figure 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 electron acceptor (electron acceptors). For that reason among experts believe that it takes a path other mechanisms for delivering the release of electrons out until it reaches far beyond the solid substance of the cell membrane. And for the latest research expert microbiologist suspected one of the characteristics that match berkerakteristik thus is "nanowires" are attached to the cell number of micro-organisms.
In research conducted by Moh El-Naggar et al. growing the bacteria Shewanella oneidensis in such a way in a condition to make teramatinya the abundant production of nanowires as well as by limiting the presence of such substances metal electron acceptors character. Experiments were then applied electrical voltage scanner device. Observations indicate the existence of a distributed electric current in this configuration. Similarly, when overhung nanowires cells set aside the flow of electric current disappeared. This research is even also for the first time successfully perform the measurement on a nominal amount of electric current flowing.
As to the success of research for the first time very clearly the events following the phenomenon of nanowires scan of the electric current magnitude which occurred making it as an important discovery for the study of recent applied research fields mikrobilogi. 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 mengimbuhkan research findings which prove the existence of electric current from the phenomenon of nanowires in order of these microorganisms as stunning results: "Fascinating ..."!
