METHOD FOR TREATING FERMENTATIVE LIQUID CONTAINING POLYSACCHARIDES FOR THE PURPOSE OF INCREASING FILTRATION PERFORMANCE AND USE OF THIS LIQUID IN SECONDARY RECOVERY OF PETROLEUM

摘要

A fermentation wort comprising a polysaccharide is treated to increase its filterability by subjecting the wort to an ultrafiltration followed by heating. The filterability of the obtained wort is excellent and it can be applied to enhanced oil recovery.
