A Group of researchers at University of California, San Diego found that Single-cell bacteria could communicate with other members by sending out electronic signals.
This study is totally different from the one that many scientists known for years.According to them bacteria coordinate by exchanging specific chemicals. This process of chemical communication known as Quorum sensing. But the recent study pinpoint it.
Bacteria lives in biofilms, which they forms on solid surface by secreting a large, slimy,glue like substance. These substance could stick to all kinds of materials– plastics, soil ,metals, medical implant materials, particles or biological tissues.
In fact, You can find this biofilms everywhere. It could be on shower heads or on your teeth aka plaque or could be on boat hulls and on rocks.
Researcher at UCSD, Jintao Liu, noticed something weird about biofilms when she studied them two years ago. According to her, biofilms would expand and stop at every two hour of regular intervals.
How Bacteria Communicate electrically?
Furthermore, scientists discovered that they possess small pores i.e. ion channels in their membranes. It can be open and shut like microscopic portholes, allowing the cells to send and receive positively charged potassium ions.
The process is almost same in neurons with the only difference of quantity. In neurons, it happens over single cells whereas in bacteria, it happens over large communities of cells.
