Hops-Derived Natural Antimicrobials
for Ethanol Production
Bacteria Control
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
FermaHop® Pro
The antimicrobial properties of hop acids against gram positive bacteria have been known and used in the brewing industry for more than a millennium and constitute a legitimate naturally derived alternative. Furthermore, hop acid extract (BetaTec’s IsoStab®) have been successfully used in dry mill and wet mill ethanol plants since 2004.
More recently, BetaTec has developed a new proprietary hop extract product called FermaHop® Pro. FermaHop Pro exhibits high stability and activity against lactic acid bacteria in a broad pH spectrum. The newly developed product can also be added to the yeast propagation tank and/or to the fermentation vessel, to inhibit the growth of lactic acid bacteria during the production of ethanol and entirely avoid the need for antibiotics or hazardous chemical use.
