It has been suggested by some research work, that a potential controlling factor in EPS biosynthesis is the availability of sugar nucleotides which is necessary for construction of the polymers (Boels et al., 2001). It was studied that microbial EPS
are not consumed as an energy source by the producing microorganism, but are released to protect the producer organism
during starvation conditions and also at extreme pH and temperature conditions (Kim et al., 2000).
