Industrial microbio

Question 1

primary metabolites are produced during the exponential phase - example?

Answer 1

alcohol

Question 2

Answer 2

stationary phase

Question 3

antibiotics are

Answer 3

secondary metabolites

Question 4

example of industrial microbio products

Answer 4

antibiotics
enzymes
food additives
chemicals
alcohol

Question 5

Fermentation refers to

Answer 5

any large scale microbial process (anaerobic or aerobic)

Question 6

wild type strains are normally not suitable, instead use?

Answer 6

mutant strains that overproduce the desired metabolites. deregulated mutant leads to large scale production of the compound

Question 7

genetical modified organisms to ___

Answer 7

overproduce desired compound. can control expression

- examples are human insulin and rennet

Question 8

production of samotpotropin

Answer 8

• human growth factor

- defeciency causes dwarfism

Question 9

Insuline (hormone) production in body

Answer 9

produced by beta cells of pancreas. insulin injection needed for type 1 diabetes

Question 10

what was the first human protein to be produced by bacteria?

Answer 10

insulin

Question 11

how do bacteria produce insulin?

Answer 11

put human insulin gene into Recombinate bacteria–> fermentation–> isolate insulin –> put into pills

Question 12

Genetically engineered pant with roundup, how?

Answer 12

Glyphosate (roundup) kills plants by inhibiting amino acid synthesis. Take roundup resistant gene from bacteria and put into plant seed. now plants are resistant. by all other weeds will die

Question 13

resistance to insects

Answer 13

put gene that encode insect toxin into plant
