Abstract

Process for disrupting cells by contacting an aqueous, cell-containing medium with a protease enzyme, wherein the enzymic contact is preceded by contact with an ionic surfactant; the polysaccharide solutions thereby produced; and a process for displacing a fluid through a well and/or a permeable subsurface formation communicating with the well, by injecting into the well an optionally diluted, aqueous solution of such a polysaccharide.
