Solenis™ Fermentation Aids

Solenis fermentation aids effectively control undesirable microorganisms while simultaneously promoting and aiding yeast propagation in the ethanol fermentation process. This family of proprietary, antibiotic-free products includes technologies specifically designed for propagation and fermentation as well as technologies that can be fed upstream for plant-wide control of competing microorganisms. Patented and patent-pending products are available.

Fermentation processes using Solenis fermentation aids typically achieve value-added benefits including:

  • Improved microbiological control
  • Enhanced yeast viability
  • Improved fermentation efficiency
  • Increased ethanol yields
  • Improved profitability

GRAS Designation

Solenis fermentation aids contain no antibiotics and do not expose distillers grains and the subsequent food chain to active, undesired antibiotic residue. All Solenis fermentation aids are generally recognized as safe (GRAS) when used to produce distillers grains for feed for food-producing animals.

How They Work

These fermentation aids significantly enhance the ability of yeast to compete with undesirable microorganisms in the critical initial stages of propagation and fermentation. They boost the metabolic functions of yeast and create a more favorable environment for yeast propagation.

The aids also hinder the propagation of undesirable microorganisms. They do so by damaging or destroying the cell membranes of these microorganisms, rendering them unable to effectively compete with yeast.

The products complement most fermentation processes in use today, including Isobutanol and second-generation processes. They are effective in both high and low pH systems.
