Modified Procedure of Starch Gel Electrophoresis for β-Casein Phenotyping

Abstract

Hence, by using tributyriu as the substrate under the optimal conditions of the test described above, we have been able for the first time to demonstrate lipolytie activity in the following lactic acid bacteria: Lactobacillus bulgaricus~ L. helveticus, L. ~a, ctis~ L. pIantarum, L. brevis~ L. viridescens, Leuconostoe mesenteroides~ and Pediocoecus cerevisiae.We have also been able to confirm the presence of lipolytic activity in L. easel, as reported by Peterson and Johnson (7).Details of this and further work on the lipolytie activity of the lactobaeilli using the pH star assay system will be reported later.
