Exopolysaccharides (EPS) are biomolecular substance with high molecular weight
biopolymers that are secreted from diversity of bacteria. They are widely used in
industrial, pharmaceutical and etc. Bacteria excrete EPS through fermentation process.
Commonly glucose is use as a carbon source for EPS production but different type of
sugar like fructose, maltose and sorbitol can be use as an alternative. Few studies
have been attempted in producing EPS using bacteria isolated from polychaetes. There
is limited study on EPS production involving polychaetes’ bacteria, only involving
Marphysa moribidii. Hence, this study will illuminate the production of EPS by a
bacteria isolated from the gut of Marphysa moribidii polychaete. The objectives include
the investigation of bacterial growth and EPS production by the polychaete bacteria in
shake flask fermentation under certain conditions. By conducting this study, the
knowledge on mechanism and biosynthesis of EPS excretion by bacteria isolated from
the gut of Marphysa moribidii could be enhanced.
