Steps for Recovering the Desired Chemical

Q. Which one of these is the role of fermentors in microbial assisted synthesis of chemicals in industries?

1. They control the temperature, pressure and pH of the broth
2. They help in producing pure chemical that we desire
3. The fermenters are the huge vessels in which the microbes grow in a broth
4. The fermenters provide sterile conditions for microbial growth

Q. Why is downstream processing required?

1. The output from fermenter is a broth and not the final product
2. Downstream processing reduces the percentage purity of the chemical
3. During downstream processing, dead microbes get processed to release the chemical
4. All of the above
