Patent filed, optimization underway
•
Yeast accumulate lipids to >70%
of their cell mass.
•
Work done in a collaboration with Advanced BioEnergy Research Centre at Indian Oil Corporation IOC.
Strains identified that grow of LanzaTech broth
using acetate as the sole source of carbon and
energy.
Algae accumulate lipids to >50% of their cell
mass.
25% of lipids content are Omega-3 fatty acids
(Specifically DHA).

Acetic acid production from H2/CO2 using A. woodii in
LanzaTech’s single fermenter system setup
• Step change in achievable
acetate broth concentration
(from 2.5 to 4wt%)
• Optimized media recipe
• Stable high level production
• Acetic acid production rates at 180g/L/d at a concentration of 30g/L were
achieved in single fermenter system.
• Selectivity of acetic acid is ~95% as no other products apart from biomass is
produced
19
Lipid composition of acetate–fed algae
Acetate consumption rates: ~80g/L/d
Lipid Composition:
• Constant across dilution rates
• Consistently ~22% of lipids = DHA omega-3 fatty acid

“Electrosynthesis” the next step for LanzaTech
Bacteria that use gases such as CO2 as their source of carbon derive the energy needed
from electrons.

electrons:
Wind
Solar

CO2
CO2
eLanzaTech converts CO2 and electrons to products with no run-off, land use
change, or environmental uncertainty issues associated with crops
Crops convert CO2 and solar energy in to
Biomass
• LanzaTech bacteria can ferment CO2 and H2
• LanzaTech have shown enhanced reactor performance with electron-assisted fermentation (Patent
application: US61/295,145)
• Prof. Derek Lovley at U Mass (Amherst) is the leading researcher in this “electrofuels” field
• Prof. Lovley and LanzaTech are establishing a joint research effort (government funded) in this area
• This work is a natural extension of the microbial, synthetic bio, and engineering work being undertaken
on the LanzaTech platform
