Bought the culture and starter medium from Amazon. I didn't dechlorinate my tap water so the first batch of culture I added yellowed and presumably died. Eventually the chlorine evaporated and subsequent additions seemed to take.

Anyone know a way to increase the concentration of CO2 going into the bioreactor? I know there are Oxygen Concentrators, but it appears that CO2 has no such luck. I guess that makes sense the whole problem with CO2 is that it is pretty non reactive.

I know I could buy a CO2 cartridge but I'd prefer a renewable resource that pulls it out of the air.

I think that means I just need to get more air into the reactor.

New idea on this one. Use the exhaust gas from an O2 concentrator or a Nitrogen concentrator as input I to the bioreactor.

Theoretically, the exhaust gas from the concentrator had the Oxygen or Nitrogen mostly stripped out, so the percent of CO2 might be higher.
