Surfactants are the complex amphiphilic compounds which reduce or lower the surface tension between the two states that is liquid-liquid or solid-liquid.
The surfactants arrange themselves in a state that their hydrophobic part is exposed in the air whereas their hydrophilic part is in the water.
The biosurfactants are produced by the micro-organisms which are considered superior emulsifiers as compared to the synthetic surfactants. Their amphiphilicity allows the insertion of the surfactant into the membrane which disrupts the integrity of the membrane.
