In this article we will discuss about the chemical compositions of cell wall in various bacteria’s. The cell wall of bacteria is made up of network of peptidoglycan (murein, mums means wall). It is present almost on all bacterial cell wall except Halo-bacterium and Halo-coccus. Because these bacteria live in marine water which contains high […]

In this article we will discuss about the mechanisms of chemo-taxis. The special proteins called chemoreceptors are supposed to be present in the periplasmic space of plasma membrane that detects the attractants and repellents. These proteins bind to chemicals and transmit signals to the other components of chemo sensing system. So far about 20 chemoreceptors […]
