Microbial surfactants exhibit various advantages over synthetic or chemical surfactants. BSs are regarded to be “green” substitutes to surfactants of chemical origin. Microbial surface-active agents, which exhibit significant surface properties, are considered as “greener surfactants.” The majority of the surfactants now available in the market for industrial and environmental applications are chemically synthesized. In the last decade, consideration toward the BSs has been raised, which is primarily due to their extensive range of functional characteristics and the diverse production potential of the producing organism. There is an emerging need for the sighting of new non-pathogenic strains with maximal production potential and exertions to commercialize through efficient downstream processing are vital to meet the future forecasts of BSs market size. Biodegradability is recognized as a vital feature, exclusion of these amphiphiles from environmental sites, and, henceforth, degradability is regarded as an important property when estimating the environmental hazard linked with surfactant use. Regarding a solo approach for comparing BSs and chemical surfactants, would not be appropriate as no one tactic would consistently measure characteristics, usage, and disposal. Furthermore, the reply to this present situation hinges on what we mean by “efficiency.” For any surface-active agent “efficiency” can be demarcated in different ways, i.e. critical micelle concentration, surface tension, and emulsification potential (the lower the concentration, the improved the surfactants), decrease in air-water surface tension, emulsification (how efficiently they stabilize two different mixtures with diverse surface tension). Even though BSs have been considered as a promising substitute for synthetic surfactants for years, but they still need to deliver on their efficacy on various fronts. It is hopeful to see that there is still abundant space is available for basic research of the molecular interactions of their surface potential, and it will be a huge step frontward to be able to fit this information into a better inclusive considerate of the interactions among microorganisms and their applications in biosurfactants applications as a greener sustainable agents. |
