Catalysts-ADY
High-Performance Active Dry Yeast for Efficient High-Gravity Ethanol Fermentation
Conventional yeast propagation and culture-based systems can lead to variability in fermentation performance, contamination risks, and lower ethanol yield due to inconsistent yeast health.
Maintaining high viable yeast cell counts and consistent yeast activity is therefore important for achieving stable fermentation performance across different sugarcane-based feedstocks.
Catalysts-ADY is a specially selected active dry yeast strain designed to deliver high fermentation efficiency, robust performance, and consistent ethanol yield. It provides high viable cell counts and exhibits tolerance to ethanol, temperature, osmotic pressure, volatile acids, and sulphites.
- Achieves ethanol titre up to 15% v/v with consistent performance
- Improves fermentation efficiency compared to culture yeast
- Reduces contamination risks through single-step propagation
- Enhances yeast viability and fermentation stability
- Reduces dependency on skilled microbiological handling
- Enables processing of multiple feedstocks without product change
- Saves energy through high-gravity fermentation
Catalysts-ADY is applicable in :

FAQ's
Conventional culture yeast may struggle under high-gravity conditions due to osmotic, ethanol, and organic acid stress. CATALYSTS-ADY is selected for higher stress tolerance, helping simplify fermentation, reduce contamination risk, lower residual sugars, and support consistent ethanol recovery.
Long fermentation cycles, high residual sugars, inconsistent alcohol levels, contamination during propagation, poor yeast viability, or excessive wastewater generation are strong indicators that upgrading to active dry yeast can improve performance.
It is a complete fermentation solution supported by process optimization, rehydration guidance, laboratory analysis, onsite technical assistance, and continuous performance monitoring to help improve fermentation efficiency.
