Summary
The pH of fodder beet pulp was varied to see how this affected solid phase fermentation by yeast. The process is for fuel ethanol production. When pulp was adjusted to a pre-inoculation pH of 3.0–3.5, ethanol yields (78–85% of theoretical, averaging 8.9% v/v) and fermentation efficiencies (97–99%) were greatest, the fermentation time was the shortest (30–39 h) and no bacterial contamination occurred.
