“…Now a days surfactants are reported for application in many fields of industry -pharmacy, food industry, design of washing agents, petroleum industry, environmental protection and agriculture (Rostas and Blassmann, 2009;Deleu and Paquot, 2004;Singh et al, 2007;Moldes et al, 2011). The biosurfactant produced by microbes are helpful in bioremediation of heavy metal, pesticides and hydrocarbon contaminated sites (Juwarkar et al, 2008). They are also used as biocontrol agent to protect plant against various diseases resulting in higher crop yields (Asaka and Shoda, 1996;Krishnayya and Grewal, 2002;Gravel et al, 2005;Snook et al, 2009;Hultberg et al, 2010).…”

Biosurfactants are amphiphilic compounds produced by microorganisms and have multifarious uses in industry and agriculture. The biosurfactant producing microbes are helpful in bioremediation of heavy metal, pesticides and hydrocarbon contaminated sites. They are also used as bio-control agent to protect plant against various diseases, resulting in higher crop yields. The present study was aimed to isolate potential biosurfactant producing bacteria from oil contaminated sites. Initially 37 bacteria were isolated among them nine biosurfactant produces were screened based on surface tension reduction, emulsification index, modified drop collapse test and oil displacement activity. The isolate FKOD36 was the most effective biosurfactant producer as it showed the maximum reduction in surface tension (35.15 dyne/cm) with an emulsification index of 66.7% and oil displacement activity of 3.7 mm. The bacterium was identified by using partial 16S rRNA sequencing and it belonged to genus Klebseilla, and was designated as Klebseilla sp. FKOD36. The strain was also capable of utilizing phenanthrene as the highest bacterial biomass was produced by this strain in phenanthrene amended MS media compared to other isolates. This suggests that selected strain Klebseilla sp. FKOD36 could have potential to degrade the hydrocarbon contaminated sites that could be helpful in conservation of natural resources.

Environmental contamination by improper disposal of industrial, mining, agricultural, municipal, and other residues is known worldwide. Various chemical-, physical-, and biological-based methods are currently being developed for removal of such pollutants from soil and water. Among these techniques, biological treatment, or remediation using microbes, is one of the most promising techniques, mainly because of its cost-effectiveness and essentially complete destruction of numerous pollutants. The major requirement for this technique is survivability of the degrading microorganisms during the process. Biosurfactants, particularly microbial surfactants, play a vital role in cases where pollutants are not readily bioavailable, by increasing the apparent water solubility of the pollutants, which could be achieved either by ex situ addition or in situ production of biosurfactants by microbes. However, due to wide application potential of microbial surfactants in the environmental sector, it is important to know their mechanisms of action, recent advances in bioremediation processes, and other possible applications. The goal of this chapter is, therefore, to provide an overview of the different types of microbial surfactants and sources, their roles in several bioremediation processes, and recent advances in the field.
