Oligosaccharides are used as therapeutic agents in infectious and inflammatory diseases, metabolic and cardiovascular disorders, transplantation, neutralization of toxins, and cancer immunotherapy. These are useful as bulking agents in diet foods and also act as pre-biotics. These activate the plant cell machinery leading to defence reactions or to plant developmental processes. They are also used as fertilizers. Gluconacetobacter hansenii PJK, a bacterial cellulose (BC) producing strain, can produce water-soluble oligosaccharides (WSOS) as a by-product from the chemically-defined medium. However, the yield of the WSOS from this medium was not enough for commercial applications. The current study deals with the optimization of medium for producing maximum amount of WSOS. The waste of beer fermentation broth was also tested as an alternative to the chemically-defined medium for the production of the WSOS. The structures of WSOS obtained were determined using various spectroanalytical techniques. Moreover, the various physical properties of the WSOS were determined to evaluate their potentials for commercial applications.
