ZyloProTM Protease for Bioethanol Production

Optimized for Yeast Nutrition and Fermentation Efficiency

ZyloPro™ is a highly active, acid proteolytic enzyme designed to enhance ethanol fermentation by improving yeast nutrition. Produced from Aspergillus niger, ZyloPro contains a blend of endo- and exopeptidases that break down plant proteins into free amino nitrogen (FAN), a vital nutrient for yeast metabolism. This non-GMO protease supports efficient fermentation and reduces the need for supplemental urea, helping producers optimize performance and profitability.

Benefits and Features

  • Increases yeast‑accessible FAN to support strong fermentation
  • Enhances ethanol production while reducing urea use
  • Improves ethanol yield by boosting nutrient conversion from plant protein
  • Achieves up to 18% higher ethanol levels vs. untreated fermentations
  • Maintains ethanol concentration at doses 30% lower than conventional proteases
  • Performs reliably under typical fermentation conditions
  • Liquid concentrate for simple handling and application
  • Contains endo‑ and exopeptidases for broad protein hydrolysis
  • Non‑GMO and Generally Recognized as Safe (GRAS)
  • Designed for consistent performance across diverse bioethanol systems

Mode of Action

ZyloPro breaks down complex plant proteins into peptides and amino acids through a combination of endo- and exopeptidase activity. This process generates free amino nitrogen (FAN), which enhances yeast health and ethanol conversion efficiency. By reducing the need for added urea, ZyloPro contributes to cleaner, more cost-effective fermentations.

Application and Performance

ZyloPro is intended for use during the fermentation stage of ethanol production. It has demonstrated:

  • Up to 48% more FAN released compared to fermentations without protease
  • Up to 18% higher ethanol yields in trials with only 50 ppm supplemental urea
  • Ethanol maintenance at 30% lower doses than conventional proteases

Actual dosage should be determined based on your plant's process parameters and production goals. Kemin’s technical team can help assess the optimal application rate.
