Title: Bioreactor.
Abstract: The present invention relates to a bioreactor comprising a first fluid distribution chamber and a first fluid collection chamber, the reactor adapted to receive at least one conduit in fluid communication between the first fluid distribution chamber and the first fluid collection chamber; wherein the reactor includes a second fluid distribution means including a plurality of distributors arranged to distribute the second fluid between the first fluid distribution chamber and the first fluid collection chamber. The invention extends to a removable insert for a bioreactor comprising a first fluid distribution plate; a first fluid collection plate; and a second fluid distribution means including a plurality of distributors arranged to distribute the second fluid between the first fluid distribution plate and the first fluid collection plate. ...

BACKGROUND OF THE INVENTION

This invention relates to a bioreactor. In particular this invention relates to a bioreactor including including membrane conduits and being adapted to received a first and second fluid.

In the biotechnology and biopharmaceutical industry, the most relevant bio-origin compounds are produced using bioprocesses involving specific cell culture systems operated and controlled within a cell culture bioreactor or module.

In general, these cell-culturing systems are characterized by several process limitations as well as fundamental-physical constraints delimiting the maximal production capacity of these established generic technologies. These limitations are expressed fundamentally as limits in mass transfer capabilities of these technologies. Examples of such known technologies include pneumatic reactors, solid state reactors and membrane conduit bioreactors.

It is obvious that the limitations mentioned above have a negative impact on the cost-effectiveness of these reactors and on the efficacy with which they function.

Furthermore, usually a specific process demands a specific type of reactor and therefore it can be extremely costly to have to purchase new process-specific reactors as they are required.

A need exist for an improved bioreactor.

A further need exists for improved reactors which are either adapted to the purpose required or which can be adapted to such purpose in a commercially viable manner.

SUMMARY

OF THE INVENTION

According to a first aspect to the present invention there is provided a bioreactor comprising: a first fluid distribution chamber; and a first fluid collection chamber, the reactor adapted to receive at least one conduit in fluid communication between the first fluid distribution chamber and the first fluid collection chamber; wherein the reactor includes a second fluid distribution means including a plurality of distributors arranged to distribute the second fluid between the first fluid distribution chamber and the first fluid collection chamber.

The bioreactor may include a plurality of conduits in fluid communication between the first fluid distribution chamber and the first fluid collection chamber. The conduits are preferably membrane conduits. In a preferred embodiment of the present invention the conduits are axially elongate having first and second ends (resembling drinking straws). Such conduits are described in U.S. Pat. No. 5,945,002 (Leukes et al.) and US Publication No. 2004/0191855 A1 (Leukes et al.), the contents of both of which are included herein by reference.

The first end of the conduits are preferably adapted to engage in the first fluid distribution chamber and the second end of the conduit is adapted to engage with the first fluid collection chamber.

The first fluid may be a liquid, for example a liquid nutrient. The second fluid may be a gas, for example, oxygen, nitrogen or a mixture thereof.

Preferably the distributors distribute the second fluid amongst the conduits. The distributors preferably distribute the second fluid in a direction transverse to a longitudinal axis of the conduits. The distributors preferably extend between the first fluid distribution chamber and the first fluid collection chamber and may be substantially parallel with the conduits. There are preferably at least two distributors, more preferably at least three distributors, more preferably at least four distributors, more preferably at least five distributors, more preferably at least six distributors, more preferably at least seven distributors and more preferably at least eight distributors.

The chambers preferably include perforated plates. The conduits may engage with or within the perforations. The conduits may engage by epoxy sealants and/or clamping plates.

The chambers are preferably spaced from each other with the conduits extending between them.
