<P><B>ABSTRACT</B></P><P>A strategy for preventing reduction of ethanol yield in fermentation caused by bacterial contamination was developed. In solid-state ethanol fermentation in which saccharification, fermentation and ethanol recovery are performed simultaneously, the addition of exogenous ethanol to the fermentation mixture at the start of fermentation at 50gkg<SUP>−1</SUP> prevented contamination, and the ethanol yield reached 0.50gg<SUP>−1</SUP>.</P>
