Core Biogenesis


Molecular Farming is the use of entire plants as expression hosts for the production of recombinant proteins. DNA is inserted into the plant in a transient or stable manner, and this DNA is then used as the code for the plant to synthesize the corresponding proteins, in our case Growth Factors and cytokines.

The protein of interest accumulates in the plant and must then be extracted and purified in order to obtain the pure final product.

Our biofactory plant, camelina sativa.

Core Biogenesis leverages an oilseed plant called Camelina sativa for the stable expression of recombinant proteins and has developed various technologies to increase the expression yield of its plants and make the extraction process more efficient and more scalable. 

In addition to scalability and cost-effectiveness, molecular farming using a stable expression method has substantial sustainability benefits: our method at Core Biogenesis doesn’t require bioreactors, nor automated vertical farming technologies, allowing for a carbon-negative production thanks to the photosynthesis mechanism of the plant.

Solving the 2 key bottlenecks in bioproduction

The expression yield

Leveraging the expertise of its CSO, Dr. Chouaib Meziadi, in plant genetics and epigenetics, Core Biogenesis has identified various combinations of genes in Camelina Sativa, that are  involved in plant defense mechanisms and that increase the expression yield of the recombinant protein expressed in the plant, by orders of magnitude.

3. Core Biogenesis technology

Increased protein expression with Core Biogenesis technology vs conventional expression methods: 

1: Untransformed C.sativa leaf (no detection).
2: C. sativa leaves expressing RFP without Core Biogenesis technology (wild type).
3: C. sativa leaves expressing RFP with Core Biogenesis technology.

All three leaves were exposed to 558 nm excitation wave for RFP revelation and under normal light. 

This piece of technology removes the first bottleneck which is the low expression yield.

Our downstream process

The fixed cost of extraction and purification represent the true bottleneck of any bioproduction method, including molecular farming.

Core Biogenesis bioproduction method leverages the oleosin fusion technology, the targeted isolation of the recombinant protein of interest to the lipid body, a specific organelle of the plant located in the seeds of Camelina sativa, allowing for the development of phase-specific downstream process development that are scalable and guarantee a final product free from impurities.

This results in a downstream process with a scalability comparable to that of the food industry, with a cGMP quality grade. 

With these two bottlenecks (expression yield and purification) solved, Core Biogenesis unlocks the access to the true scalability of molecule farming, the use of plants for the bioproduction of recombinant proteins.
