The main functions of bio-surfactant in microbial cells are
emulsification of water insoluble substrates such as hydrocarbons
and facilitate its transport into the cell to stimulate the growth.
Similarly adhesion and desorption of cell is essential for the
survival of microbes in unfavourable conditions like toxin
accumulation, limited nutrients availability.
In this article, have presented the application of biosurfactant,
methods used for its isolation, production and
purification.
