Abstract
Buchnericin LB produced by Lactobacillus buchneri LB was purified to homogeneity by a rapid and simple three-step purification procedure including freeze drying, silicic acid adsorption/desorption and cation-exchange chromatography. After the silicic acid and cation-exchange chromatography steps, the activity of buchnericin LB was recovered by 85 and 25%, and its purity increased about 111 and 2,500 fold, respectively. It was determined that the adsorption of buchnericin LB to silicic acid and cation-exchange chromatography was dependent on the pH of the suspending environment. The molecular weight of buchnericin LB was determined to be about 4.0 kDa by tricine SDS-PAGE.
