Abstract

  Lysozyme from saliva of Bali cattle (Bos sondaicus) was successfully isolated through an aqueous mixture system of polyethylene glycol (PEG 4000) and salt (Na2SO4). About 100 µg/ml lysozyme of 14.2 kDa, determined through sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), per 4800 µg/ml saliva was obtained. Based on turbidity assay of Staphylococcus aureus, it was revealed that inhibition activities of 40 µg/ml isolated lysozyme were comparable to 800 µg/ml of a commercial hen egg white lysozyme.   Key words: Lysozyme, Bali cattle, Bos sondaicus, PEG, aqueous mixture system.
