This study aimed to determine the effects of using different carbon sources to the growth of different strains of phytase producing bacteria based on optical density (OD), colony forming unit (CFU), and their phytase production. All four strains of bacteria potentially producing phytase have been isolated from several hot springs in Malaysia, which were in Labis, Johor (L3), Dusun Tua, Selangor (RT), Ulu Legong, Kedah (A) and Ranau, Sabah (B9). The bacteria were grown in nutrient agar (NA) and modified Phytase Screening Medium (PSM) liquid media for culture enrichment. Glucose and lactose were used as the carbon source and growth was done under optimum culture conditions (pH 5.5, 37˚C, 200 rpm) for 72 hours through batch culture method using a shake-flask scale.
