METHOD OF OXYGENATING YEAST SLURRY USING HYDROPHOBIC POLYMERIC MEMBRANES

摘要

Disclosed is an economical method of efficiently oxygenating yeast slurry without bubble formation. The method employs a membrane oxygenator comprisin g at least one hydrophobic, microporous membrane having a gas side and a liqui d side. The yeast slurry flows over the liquid side of the membrane; oxygen is delivered to the gas side of the membrane and passes through the pores to th e yeast slurry.
