Turning Bioreactor into Reality
Bioreactors - or fermentators - are equipments widely used in the industry to produce a variety of enzymes, antibodies, among others. There are also bioreactors employed in effluent waste treatment.
In partnership with professors and experts in bioreactor (Fernando Garcia and Osmarina Godoy) we elaborate a fermentation in a DIY style using an old autoclave as base and its parts found in mechanic garage leftovers. “Accidentally” our bioreactor looked like the Star Wars R2D2 and, we loved that! Batches was conducted having manual addition in nutrients and inoculum. The vessel allowed 5 liters approximately.
The vessel is hermetically closed, however there is an optional air entrance that can be released if necessary an aerobic process. To move the air to our “R2D2” we used an aquarium air pump. The air is guided by a 7mm tube, passing by a particle filter (the same used in car fuel filter). Followed by that the air passes by a UV light (specific for gas sterilization) , only then it arrives to the process (clean and fresh air...for our fellows).
Inside the vessel we added a water pump in order to generate a liquid flux and oxygen. Any generated gas can be out through a 7mm tube driving it to an activated charcoal before been released to the atmosphere.
