Hops-Derived Antibacterials for Ethanol Production

IsoStab®, LactoStab®, BetaStab® and LupuStab® are derived from natural acids found in hops. They will effectively control gram-positive bacteria in fermentation during ethanol production.

Key advantages of Isostab®, LactoStab®, BetaStab® and LupuStab®:

  • Eliminate the use of antibiotics.
  • Control lactic and acetic acid formation.
  • Add value to co-products with antibiotic-free DDGs.
  • Protect your equipment from harsh chemicals.
  • Potentially increase ethanol yields.
  • Derived from the natural growing hop plant.
  • Thermally stable.
  • pH tolerant.
  • Easy to handle and store.
  • Food grade, Kosher, Halal, GRAS, safe to handle.
  • Cost effective
  • “Invisible” to yeast, with no negative effect on yeast activity or vitality

How It Works


Hop Acid - Nutrients - How it Works

IsoStab®, LactoStab®, BetaStab® and LupuStab® inhibit bacteria’s glucose intake, without affecting yeast activity

BetaTec extracts naturally occurring acids from the hops flower to produce IsoStab®, LactoStab®, BetaStab® and LupuStab®. 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 antibiotics. IsoStab®, LactoStab®, BetaStab® and LupuStab® kill bacteria, but have no effect on yeast activity. In fact, without competition from bacteria, yeast do their job more effectively and alcohol yield benefits!
