Introduction In the prevailing environmental status quo, escalation of anti-biotic resistant bacterial strains is becoming a threat to human health worldwide, since it is causing thousands of infections The plasma membrane or bacterial cytoplasmic membrane is composed of a phospholipid bilayer and thus has all of the general functions of a cell membrane such as acting as a permeability barrier for most molecules and serving as the location for the transport of molecules into the cell. In addition to these functions, prokaryotic membranes also function in energy conservation as the location about which a proton motive force is generated. Unlike eukaryotes, bacterial membrane…
