Applications / Alcohol & fermentation
Alcohol and fermentation: define the process stage
Use the substrate and process stage to frame your enzyme enquiry. Confirm each product’s intended use and operating guidance before a trial.
Follow the process, then define the trial
Raw material and preparation
Identify the feedstock and record changes in composition or solids. Keep the sampling point consistent so that results can be compared between runs.
Liquefaction and conversion
Separate a handling or viscosity objective from a conversion objective. Record the stage, temperature, pH and residence time where each observation is made.
Fermentation and review
Record the baseline, measurement method and downstream conditions. Review results alongside other process changes before attributing an effect to an enzyme.
Separate the questions before choosing an option
A useful enquiry distinguishes the symptom from its possible causes. The checks below structure the discussion; they are not a diagnosis.
Handling difficulty
Locate where the restriction first appears and compare solids, temperature and equipment conditions with the baseline.
Conversion or residual sugars
Identify what is being measured, the sampling time and analytical method. A result from one stage does not describe the whole process.
Repeatability
Compare like-for-like material and operating conditions. Record departures from the plan, including changes unrelated to the enzyme.
Record conversion and fermentation separately
Keep material handling, conversion measurements and fermentation results connected without merging their different endpoints.
Preparation and conversion record
Identify feedstock, solids basis, treatment sequence and sample locations. Record the product, batch, addition time and dosage basis for any enzyme candidate, together with actual temperature, pH and contact time.
Fermentation time profile
Use the same sampling schedule and analytical method for reference and trial. Include the starting material record and other process changes so the final comparison is not detached from upstream conditions.
Review the limiting step
State which observation changed and which did not. Decide whether to repeat the comparison, investigate preparation or request a product-specific review; a single final value cannot establish the cause.

Process-to-evaluation matrix
Demonstration structure for reviewing an application. Candidate names, approved conditions and actual results will be supplied after technical review; this is not an operating instruction.
| Stage | Question | First check | Candidate status | Evidence to record |
|---|---|---|---|---|
| Preparation / handling | High viscosity or difficult transfer | Check material, solids basis and sample temperature | Liquefaction candidate — product confirmation required | Viscosity method and transfer observation |
| Conversion | Residual material at the chosen endpoint | Identify the component and analytical method | Conversion candidate — suitability to be reviewed | Reference and trial measured on the same basis |
| Fermentation | Slower time profile | Compare upstream preparation and actual conditions | Do not assume an enzyme is the cause or remedy | Time-stamped profile and product-quality checks |
