Industrial Enzymes & Bio-Ingredients worked example

Fermentation Yield at 63% target fermentation yield: a worked example in industrial enzymes & bio-ingredients

This worked example runs the fermentation yield numbers for a tougher week than the baseline: 63% target fermentation yield instead of the typical 88%. Calculate fermentation yield for an enzyme or bio-ingredient batch using recovered product amount, theoretical product amount, and the target yield percentage.

The inputs for this scenario

  • Recovered enzyme or bio-ingredient amount: 820 kg (held at the documented default)
  • Theoretical batch product amount: 1,000 kg (held at the documented default)
  • Target fermentation yield: 63 % (the input this scenario stresses; the baseline uses 88)

Working through the calculation

  • The calculation starts from the formula this tool documents: Fermentation yield = recovered enzyme or bio-ingredient amount ÷ theoretical batch product amount × 100.
  • Fermentation yield works out to 82 % at these inputs, and this is the headline figure for the scenario.
  • Fermentation yield gap to target works out to -19 points at these inputs.
  • Recovered enzyme or bio-ingredient amount works out to 820 count at these inputs.
  • Theoretical batch product amount works out to 1,000 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target fermentation yield sits at 88% and the headline result is 82 %, this scenario lands almost exactly on the baseline at 82 %.
  • Use it after each batch harvest or recovery run to benchmark performance against the theoretical maximum and your process target. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Fermentation yield: 82 % (headline result)
  • Fermentation yield gap to target: -19 points
  • Recovered enzyme or bio-ingredient amount: 820 count
  • Theoretical batch product amount: 1,000 count
