Optimization of condiction for Exopolysaccharid(EPS) production from Lactobacillus Plantarum localy isolated

Abstract

The optimum cultural and ecological condition for Exopolysaccharid Production from Lactobacillus PLantarum localy isolated were studied Results revealed that , using production medium ( simplified synthetic medium)containing date juice (5%) as a carbon source and yeast extract (0.2%) as a nitrogen source, the media was supplemented with a total concentration 0.9% of (magnesium sulphate and potassium phosphate ) as mineral salts. The primary pH was adjusted to 6.5 and the inoculum size was 3%(v/v), isolate were grown under anaerobic condition at 35 Co for 24 h and the EPS extracted with ethanol 95%.
