title: Strategy for preventing bacterial contamination by adding exogenous ethanol in solid-state semi-continuous bioethanol production.
abstract: 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 50 g kg(-1) prevented contamination, and the ethanol yield reached 0.50 g g(-1).
