Abstract

A novel method for the lysis and subsequent fractionation of bacterial constituents from Mycobacterium paratuberculosis strain 19698 (M. paratuberculosis) and Escherichia coli strain DH5 alpha utilizing the technique of matrix solid-phase dispersion (MSPD) is described. Bacteria were blended with octadecylsilyl (C18) derivatized silica to obtain cellular lysis. The blended material was used to prepare a column which was sequentially eluted with solvents of increasing polarity. Fractionation of cellular components was confirmed by analysis of the solvent extracts. The possible applicability of the MSPD technique as a general method for the lysis and fractionation of bacterial components is proposed.
