In Iowa, ingredient manufacturer Kemin Industries announced the launch of FermSAVER, a tea-extract product utilized during yeast fermentation for ethanol production, as part of its Kemin Bio Solutions portfolio. The firm said that FermSAVER was developed to help reduce stress when yeast is exposed to excess heat generated during the summer months. Supplementation with FermSAVER has been shown to improve ethanol production during periods of heat stress compared to yeast alone, Kemin Industries said. “Managing heat during ethanol production is critical to any bioethanol facility,” said Jason Ackerman, General Manager, Kemin Bio Solutions. “We are thrilled to introduce FermSAVER, which can give ethanol producers peace of mind during high-heat periods by helping to maintain productivity.” During industrial fermentation, yeast generates excessive heat through normal metabolic processes. In the absence of cooling — and during summer months when chiller effectiveness is lower — yeast fermentation is significantly affected, resulting in reduced ethanol production. “Ethanol manufacturing facilities have typically relied on cooling towers to reduce the negative consequences of heat generated during fermentation, but cooling towers may fail or become overwhelmed during periods of high heat. When this occurs, the facility must take action that is costly and may still not correct the production loss. FermSAVER can decrease the stress experienced by yeast during periods of increased temperature, ultimately leading to improved ethanol yield,” the company said.
