E. coli advantages E. coli disadvantages
, Petrochemical: crude oil (using oil biorefinery). 1. Traditional: production of foods (beer,
There is a world shortage of crude oil. cheese, brad, soy sauce)
Biotechnological: uses sugars/biomass. One 2. Industrial: microorganisms discovered,
glucose produces 2 ethanol and 2 ethene. There production of for example
is the food vs fuel debate, so another carbon acetone/butanol and antibiotics
source has to be found (also shortage of 3. Modern: gene technology
substrate).
Red: medical/healthcare Feasibility: based on market, politics and
Green: agricultural/food competition
Blue: marine Competition:
White: biobased technology, replacing Availability substrate (price)
petrochemical production, industrial Relation between price and volume
Purity of the product/concentration in
water
Production of carbon dioxide
Low pH: fungi Profit (must be worthwhile, well reward long
Alcohols: yeast term), people (no social problems/conflicts) and
planet (must be environmentally good, must not
destroy the planet)
Folding (SS bridges by disulfide Safe host: no virulence factors and no toxins
oxidoreductases, chaperone proteins, (preferred: long term usage before)
secretion) GRAS status: generally recognised as safe (for
Peptide chain adjustment foods). The tolerated amount of microorganisms
Sugar residues (pharmaceutical)

Some strains produce toxins Can form inclusion bodies’
Forms a lot of proteins K12 does not produce toxins
Can incorrectly fold human proteins
