QA.A bio-PDO production process will also produce microbial biomass. A huge surplus biomass of roughly 10% of the PDO mass should be expected. A good use of this microbial biomass could be food of feed.

Question

Which organism properties disqualify their use in food/feed production from microbial biomass?
1/Pathogenicity 2/Phage sensitivity 3/Non-GRAS (GRAS = Generally Regarded As Safe status granted by FDA)4/ High growth rate 5/ Low production yield 6/Aerobic 7/Anaerobic

QB.Please indicate drivers that promote the transition to a biobased economy.
1/Increasing antibiotic resistance 2/Concerns about climate change 3/Novel nanotechnology 4/Energy-security of nations 5/Lowering waste production (incl. CO2)6/ Development of better storage options for electrical energy 7/Depletion of fossil resources 8/Obamacare 9/Increasing use of wind energy 10/Increasing availability of birth control methods 11/The need for sustainable organic (carbon-containing) molecules 12/A growing world population that deserves access to basic needs and a good environment.13/ The possibility to add sustainable value to the food chain (integral use of biomass) 14/Increasing feasibility of 3D printing technology 15/Decreasing use of solar energy 16/Opportunities for local farmers 17/Decreasing population growth

Answer 1

2/Concerns about climate change
4/Energy-security of nation
7/Depletion of fossil resources

Answer 2

For question A, the answers are going to be:
-Pathogenicity
-Non GRAS
