FermSAVERTM for Bioethanol Production
FermSAVER™ is designed to strengthen yeast performance during fermentations challenged by heat and elevated ethanol levels. Under these conditions, yeast generates reactive oxygen species that damage cell membranes, proteins, and DNA, reducing vitality and ethanol output. When added at the start of fermentation, FermSAVER™ helps protect yeast from oxidative stress, supporting more consistent fermentation, improved efficiency, and ethanol yields.
Benefits and Features
- Maintains ethanol yield under heat/ethanol stress
- Protects yeast while preserving viability
- Improves efficiency even with limited cooling
- Dry powder; easy to handle and dose
- Food‑grade, non‑GMO, Kosher
- Compatible with standard plant equipment
Mode of Action
Heat and rising ethanol concentrations increase oxidative stress inside yeast cells. FermSAVER™ provides antioxidant support that helps neutralize these stressors, stabilizing yeast metabolism and preserving cellular function. This results in more consistent fermentation and improved ethanol output—without negatively affecting yeast viability.
Application and Usage Guidelines
FermSAVER is ideal for reducing losses in yeast vitality caused by heat or ethanol stress in fermentation processes experiencing elevated temperatures. It is well-suited for bioethanol facilities looking to improve ethanol yield under thermal stress and for systems where yeast viability must be maintained without the need for cooling upgrades.
Usage Guidelines:
- Recommended dose: 0.0005%–0.001% (w/w, dry corn basis)
- Optimal dosing varies by yeast strain and plant conditions
