I am looking for any advice, guidance or pointers surrounding the topic of a DIY bioreactor. The bioreactor does not need to be industrial size or grade and to contextualise, would be used to grow and harvest enough recombinant insulin producing yeast to produce enough insulin for an individual or small community containing individuals with type 1 diabetes. No small contribution or tid-bit of info would go unappreciated as I am beginning here with a lot of knowledge around biology/biotech but little-to-no knowledge of engineering. Materials, pumps, internal/external pressures, filters, nutrient mixtures, filtration processes post cultivation, time-scales, energy requirements. Literally anything provided would be greatly appreciated.
