lversion? % substrate conversion compare with (4) at 90 i) How does the biomass productivity at 90 the maximum possible? QUESTION 2 (15 marks) You are assigned to design and fabricate a bubble column react the processes such as batch, fed-batch and continuous system kg/day of butanol production. As a biochemical engineer, identify the options of a) at the capacity of 500 follows fed-batch and continuous 5) Justify the selection of the process among the İ) processes based on the high yield and productivity of the butanol. ii) Identify the design steps of bioreactor for the selected process ii) Determine the size and volume of the bioreactor based on rate of production 6) given (kg/day)

Answer 1

Let us first start with " What is Bioreactor?"

This is basically a device in which the organisms, under the optimal tenperature and appropriate environment, Re cultivated to form the desired product.

1) The batch mode provides the highest solvent yield, whereas the fed-batch mode does not support solvent production.

The highest butanol yield and productivity was 0.21 g-butanol/g-glucose.

Continuous mode and batch mode were suggestive of higher butanol yield at the higher dilution whereas fed-batch mode is not because of the more time needed for its fermentation.

2) Butanol can be made from lignocellulosic biomass.

3) The size and volume of the bioreactor mainly depends on the type of material of which it is made. Stainless steal bioreactor holds capacity of 316 L.

Different bioreactors hold different different volume.

The laboratory fermentor holds 1-50 L, Plant scale bioreactor holds 2-500 meter cube.
