Microbial exopolysaccharide are produced by various genera of bacteria and fungi. The maximum EPS production from G. lucidum and L. fusiformis from both medium were estimation at 89.33 ± 4.04 g/100ml and 84.33 ± 3.58 g/100ml at dry weight in EPS basal medium. The carbohydrate concentration was higher in EPS malt medium for G. lucidum 1.63± 0.11mg/ml and L. fusiformis1.60± 0.27mg/ml. The protein concentration was higher in EPS basal medium for G. lucidum 1.84± 0.23mg/ml and L. fusiformis1.27± 0.45mg/ml. The sulfate concentration was higher in EPS malt medium for G. lucidum 0.95± 0.05mg/ml and L. fusiformis 0.82± 0.12mg/ml. The chemical compositions of EPS from both basal and malt medium. The percentage of elements carbon, hydrogen, nitrogen and sulfur content of EPS from G. lucidum and L. fusiformis. This study suggested that the EPS from G. lucidum and L. fusiformis could potentially be used as antibacterial activity.
