ABSTRACT:
A disposable fermenter that may be used in the place of a more expensive jar fermenter giving the same performance in a temperature controlled room in place of a sterilized room, with the advantage of not being made of glass which breaks and which may be transported as is, by just sealing the bag.
A flat tube made of plastic film is inserted into the bottom of the bag with the tube sealed to the bag, leaving an opening through the tube so the opening may not be closed. Once the addition of liquid, semi fluid or solid media is made, the breather is set and the bag opening is sealed, the bag is sterilized before or after the bag opening is sealed and the aeration is done through the flat tube.
