Hops-Derived Natural Antimicrobials
for Ethanol Production
Another value added benefit of using our bacterial control program is the ability for ethanol plants to sell antibiotic-free distiller grains. Using BetaTec Hop Products, ethanol plants now have the capability to kill yield-robbing gram-positive bacteria without using antibiotics or hazardous chemicals. As the FDA and consumers drive stricter requirements of many co-products used in the feed industry, ethanol plants need to consider regulatory changes and public perception as antibiotics are becoming heavily scrutinized.
How It Works
Inhibits bacteria’s glucose intake, without affecting yeast activity.
BetaTec extracts naturally occurring acids from the hops flower to produce IsoStab® and LactoStab®. These natural acids are absorbed by the bacteria cell and lower its pH. This inhibits the cell’s ability to transfer glucose through the cell wall. In essence, bacteria commonly found in ethanol production are starved to death. They can’t eat. They can’t multiply. And they die. All without the use of chemical antibiotics. Better yet, the bacteria do not recognize IsoStab® and LactoStab® as a threat, and therefore do not develop a resistance. In fact, without competition from bacteria, yeast do their job more effectively and alcohol yield benefits!
