What is Bacterial Chemotaxis?

Bacterial chemotaxis is a process where bacteria move directionally in response to chemical stimuli in their environment. Such behavior enables them to navigate toward favorable conditions, such as areas rich in nutrients, and away from toxic substances. The mechanism involves receptor proteins on the bacterial surface detecting chemical signals, which then trigger changes in the rotation of their flagella, resulting in movement. This sophisticated navigation system is crucial for bacterial survival, adaptation, and pathogenicity, allowing them to effectively respond to environmental changes and optimize their living conditions. Understanding bacterial chemotaxis provides insights into microbial behavior and potential therapeutic targets....

Discovery of Bacterial Chemotaxis

The discovery of bacterial chemotaxis was first discovered by T.W. Engelmann in 1881 and W. F. Pleffer in 1884 in the bacteria and in the ciliates in 1906 it was discovered by H. S Jennings.

Signal Transduction Process in Chemotaxis

The signal transduction process in bacterial chemotaxis begins when chemoreceptors on the cell surface detect chemical gradients. These chemoreceptors transmit the signal to the inside of the cell, initiating a phosphorylation cascade involving a series of proteins, including CheA and CheY. CheA autophosphorylates and transfers the phosphate to CheY, which then interacts with the flagellar motor, altering its rotation. This changes the bacterial movement between “running” and “tumbling.” Adaptation mechanisms, involving methylation and demethylation of chemoreceptors, reset their sensitivity, allowing bacteria to respond continuously to environmental changes, ensuring efficient navigation towards attractants or away from repellents....
