ECOSynBioThis funding opportunity seeks submissions to establish new technologies to significantly improve the carbon efficiency of bioconversion platforms through the accommodation of external reducing equivalents.

Proposed systems of interest include, but are not limited to:
(1) carbon optimized

fermentation strains that avoid CO2 evolution, (2) engineered mixotrophic consortia or systems that avoid CO2 evolution, (3) biomass or gas fermentation with internal CO2 utilization, (4) cell-free carbon optimized biocatalytic biomass conversion and/or CO2 utilization, and (5) cross-cutting or other proposed carbon optimized bioconversion schemes.

All systems will need to demonstrate the capacity to accommodate external reducing equivalents to optimize the carbon efficiency of the system as compared to traditional fermentation systems (i.e.

the sum of the recoverable energy contents of the products is greater than the energy content of the biomass or primary carbon feedstock).
