Modified bioreactor
First Claim
1. Bioreactor apparatus for culture of living matter in a liquid medium comprising a plurality of tubes connected at one end to a primary manifold section and at their other ends to a secondary manifold section such that a flow of liquid containing said living matter can be established within said manifolds and tubes, wherein the flow of liquid medium in said manifolds and/or said tubes is capable of control by at least one gas injection means in communication with the primary manifold section and at least one gas injection means in communication with the secondary manifold section.

Abstract
Bioreactor apparatus for culture of living matter in a liquid medium includes a plurality of tubes connected at one end to a primary manifold section and at their other end to a secondary manifold section such that a flow of liquid containing the living matter can be established within the manifolds and tubes. The flow of liquid medium in such manifolds and/or tubes is capable of control by at least one gas injection device in communication with the primary manifold section and at least one gas injection device in communication with the secondary manifold section. Such an arrangement provides finer control of the flow conditions in the tubes forming part of the bioreactor and of the environmental conditions for culture of the living matter. The arrangement can have a relative simplicity of design which also permits a reduction in the total number of tanks and/or control loops usually associated with bioreactor apparatus of this type.

8. Bioreactor apparatus including at least two generally tubular coils wound helically to permit gaseous products to be carried out of the coils located one above the other or in grouped batches around an upstanding support structure, the coils having inlets to receive a flow of liquid medium within which biomass or other living material can be cultured and an outlet for said medium, the inlets of the coils arranged in liquid communication with a primary manifold and the outlets of the coils arranged in liquid communication with a secondary manifold, both said manifolds being in liquid communication whereby a flow of liquid medium can be provided from the primary to the secondary manifold, primary flow control means being provided to act upon liquid medium in or flowing from the primary manifold and secondary flow control means provided to act on liquid medium in or flowing into the secondary manifold, the primary and secondary flow control means being adjustable whereby flow of liquid medium through the coils can be varied by adjustment of either or both said flow control means.
