The results indicated that the EPS production varied with five different carbon sources. The predominant carbohydrate compositions in EPSs identified were glucose and mannose. Then, FT-IR spectral analysis revealed prominent characteristic groups in the EPSs. Furthermore, thermogravimetric analysis (TGA) indicated the EPS with lactose as the carbon source showed different degradation behavior as compared to the other four EPSs, probably due to larger ribose content as one of major monosaccharides in the EPS. The variation also affects the antioxidant activities investigated by using hydroxyl and DPPH radical scavenging assay. Sucrose was the best carbon source from the viewpoint of antioxidant activity due to the relatively high xylose content in the EPS. %8 2015-02-26
