• Strain 1: Gives a 20% improved yield of product. Productivity and product concentration remain the same.
• Strain 2: Gives a 20% improvement in productivity. Yield and product concentration remain the same.
• Strain 3: Gives a 20% improvement in product concentration. Yield and productivity remain the same.

Question 1:

For each strain make a product concentration time plot to show the effect of introducing a new strain on the fermentation

Question 2:

Assuming you make the same total amount of product in a year (to match the market) and making any other assumptions as required, then complete the following table

Business development	Strain 1	Strain 2	Strain 3
Characteristics of the strain?
What OPEX savings will be made by introducing the new strain?
What CAPEX savings will be made by introducing the new strain?
Are there some extra costs?
Outline a development plan to introduce the strain.
How would you estimate the cost of the development plan?
How do you know if you make money by implementing the new strain?

OPEX: Operating cost (e.g. cost of raw materials)

CAPEX: Capital cost (e.g. cost of equipment)
