Bioethanol

NOVA™ EZL is a liquid formulation containing ethyl lauroyl arginate (ELA) that has shown to be effective against both gram-negative and gram-positive bacteria.¹ NOVA EZL is formulated to act as a surfactant, targeting bacterial cell membranes and cytoplasm throughout the propagation and fermentation stages of bioethanol production. NOVA EZL provides a unique antibiotic-free approach that effectively hinders bacterial resistance, ensuring a cleaner and more efficient bioethanol production process.

NOVA EZL is an effective antimicrobial for enhancing a bacteria control program for bioethanol plants interested in antibiotic-free ethanol production.

Key Features:

• Antibiotic-Free: NOVA EZL is an antimicrobial alternative to traditional antibiotics.


• Broad-Spectrum Efficacy: NOVA EZL demonstrates efficacy against a wide range of both gram-negative and gram-positive organisms. This ensures comprehensive protection throughout the entirety of the bioethanol production cycle.

Characteristics:

• Liquid formulation suitable for facilities preferring automated dosing
• Packaged in 1,000 kg totes
• Effective from pH 3 to 7
• Certified GRAS and Kosher 

FermSAVER* is a tea extract for use during yeast fermentation.  FermSAVER was developed to help reduce stress when yeast are exposed to excess heat generated during the summer months when chiller efficiency is low.  FermSAVER has been shown to increase ethanol production during heat stress compared to yeast without FermSAVER supplementation.

The enzyme alpha amylase is used by the bioethanol industry during the liquefaction stage to hydrolyze starches found in corn from long chains to shorter chains known as dextrins. The  ZyloZyme® AA is a highly active, non-GMO, alpha-amylase produced from Bacillus subtilis for use in the production of ethanol by fermentation.

For ethanol plants interested in the flexibility to optimize its production with a stand-alone and cost-effective Alpha-amylase, ZyloZyme® AA  is a specialized enzyme allowing plants to fine tune the amount used to break down starch, reduce viscosity and improve production output.

Benefits:

• High liquefaction temperature stability
• Generates high dextrose equivalents
• Reduces viscosity
• Non-GMO
• AAFCO Table 30.1

 ZyloZyme^® GA is a highly active, non-GMO glucoamylase specifically formulated for the fermentation process in bioethanol production. Developed using Aspergillus niger, ZyloZyme GA efficiently releases glucose from dextrins during fermentation. This glucose serves as a vital substrate for yeast, enabling them to produce ethanol effectively. ZyloZyme GA is recommended for use at low doses, typically ranging from 0.024% to 0.03% of weight enzyme/weight of dry corn.* 

Characteristics

• Liquid formulation
• Single enzymes packaging 
• AAFCO Table 30.1
• Non-GMO 

*Actual dose will depend on processing parameters and desired results.

Cellulase liberates fermentable sugars from cellulose during fermentation, increasing ethanol production and releasing corn oil that had been bound in the fiber. Studies show ZyloCell cellulase increases ethanol yield between 1 and 3%, giving you the opportunity to apply for cellulosic ethanol credits.

A concentrated dry product, ZyloCell stores compactly and requires no refrigeration. ZyloCell’s dry powder is supplied in water soluble bags that eliminate safety hazards from dust and are easy to incorporate at the desired dose. Kemin’s technical service team will help you optimize the dosage of the enzyme.

ZyloCell cellulase for corn kernel fiber:

• Increases ethanol yields 1-3%
• Decreases viscosity
• Concentrated dry powder for easy handling and accurate dosing
• 12-month stability for longer shelf life without refrigeration
• Add cellulosic ethanol to the bottom line 

Top yeast performance requires ample nutrition, with biologically available free amino nitrogen (FAN) being one of the most important.1 Plant feedstocks, while containing protein, lack sufficient FAN to meet the protein requirement of yeast. Thus, external nitrogen sources such as urea and ammonia are used to provide adequate nitrogen during fermentation.

Kemin’s unique fungal acid protease, ZyloPro, provides yeast nutrition and can reduce urea requirements to optimize yeast performance and increase the profitability of your ethanol plant.

ZyloPro protease is a highly active enzyme that hydrolyzes proteins in the feedstock itself to continually release FAN to boost yeast growth during fermentation, thus reducing urea use.

Kemin provides tailored customer lab services and technical expertise to help you maximize the value of your ingredients. By helping you identify the most efficient application rate of our stand alone ZyloPro protease, we can ensure you’re getting the maximum value from your enzymes.

ZyloPro is an economical supplemental enzyme:

• Improves yeast performance
• Offsets urea additions
• Concentrated liquid
• Effective at typical fermentation parameters
• Non-GMO and Generally Recognized as Safe (GRAS)
• Available in totes for ease of handling and storage
• Increase the profitability of your plant
