Biosurfactants are a class of surface-active molecules derived from bio based origins such as plants and microorganisms as well. This diverse group of surface active molecules possesses both hydrophilic and hydrophobic moieties in their structure which allows their partitioning the liquid/liquid, gas/liquid or solid/liquid interfaces resulting into lower interfacial tension. This facilitates their emulsification, foaming, solubilization, detergent and dispersing functioning. This nontoxic, biodegradable and eco- friendly bio-molecules are competent to replace/blend with their chemically synthesized counterparts and divulge themselves as a green alternative to be applied in the application field of food, cosmetic, pharmaceutical, petrochemical and others. The chemical composition of bio-surfactants depends on the substrate and the microorganism present. They are also divided into two large sections based on their molecular weight namely low molecular weight and high molecular weight bio-surfactants. The high molecular weight bio-surfactants are also known as bio-emulsifiers. From the scientific investigations of recent times, it is observed that the bio-surfactants and bio-emulsifiers are widely used in the field of applied science.
