Fermentation is like tuning a high-performance engine. Every part\u2014from the fuel mix to the temperature gauge has to be just right. But what happens when the engine overheats? In ethanol plants, high temperature fermentation can throw the whole system off balance. Let\u2019s look under the hood and troubleshoot the most common issues that stall your fermentation.<\/p>\n\n\n\n

<\/p>\n\n\n\n

High-temperature fermentation brings a variety of benefits to fuel ethanol production, including increased yields, faster fermentation times and reduced cooling costs. However, high temperatures can also increase the toxicity of ethanol to yeast cells\u2014inhibiting fermentation. Ensuring the right thermotolerant yeast strain and conditions are key for optimal performance but there are additional steps ethanol producers can take to potentially limit the negative impact. Explore our top three tips for managing high temperatures below\u2014both before and during fermentation.<\/p>\n\n\n
