9. Secreción de aceites no-toxica
Non-toxic mechanism
Secreted LDs spontaneously separates, sidestepping
harvesting/extraction
Works by interactions between proteins on LDs and cell membrane
or other cellular components
Platform makes GPB uniquely positioned to implement oil secretion
in algae

10. Beneficios de secreción de aceites no-toxica
BASE CASE: GPB CASE:
• Milk harvested by killing cow • Milk harvested through secretion and cow returned to pasture
• Majority of energy Making cow • Majority of energy (grass) goes into making milk
• If cows are milked daily, there is no benefit to having cows that can
store more than one day’s worth of milk
MILK + MILK

11. Modelado Tecno-económico
Oil productivity model + operational & capital costs
• Physics: energy balanced,
reasonable energy inputs
•Biology: realistic growth and
enzymatic rates, cell densities, PSE
• Interaction between variables
(e.g., cell density affects total
energy captured)
• Pilot and commercial capex and
operational cost for PBRs and open
ponds (with Tryg Lundquist, PhD at
Cal Poly)
12. Modelado Tecno-económico: valor de GPB
Secretion
• Enables continuous process through recycling of cells after secretion
• Most benefit through higher TAG Productivity
• Elimination of several costly process steps in TAG recovery
Oil metabolic engineering
• Improved redirection of light energy into TAGs
• Very high oil content levels not necessary with oil secretion
Other
• Identify additional bioengineering solutions
• Prioritize R&D projects based on synergies and on relative impact in cost
Validation
We can reach $50/bbl with realistic performance metrics for each of our
genetic engineering solutions

Algae acts a catalyst that converts CO2 and sunlight into TAGs
efficiently, without being consumed in the process

Editor's Notes
Stable transgene expression Consistent transgene expression Much higher level of transgene expression More expressing transformants Access to all cellular compartmentsRNAi functional Strain health and stability #2 Algae has the ideal characteristics for an ideal renewable energy platform.satisfy increasing energy demands + mitigate effects of climate change+ protect increasingly scarce natural resource Minimize/avoid competition with arable land for agriculture High oil productivity per acre (10x-100X over plants) Use waste water and saline water, reducing competition for limited freshwater supplies Recycle carbon from CO2-rich flue emissions from power plants and other industrial emitters
GPB rnai- gives benefits of starch knockout/mutant- more oil- without drawbacks on growth rate.
A NOTE ON MILK STORAGE CAPACITY: There is a limit to how much milk a cow can produce in one day, since they can only process a fixed amount of grass (energetically limited) If cows are milked daily, there is no benefit to having cows that can store more than one day’s worth of milkBASE CASE: Once grown, cow produces milk which is harvested by killing cow Majority of available energy (grass) goes into making cow GPB CASE: Milk is harvested by secretion from cow (milking) and cows returned to pasture Roughly 100% available energy (grass) goes into making milk (once cow population is established)
