Abstract: Methods and systems are provided for the separation of solvents, including, but not limited to, butanol, from a fermentative solventogenesis reaction medium that utilizes Clostridium beijerinckii NCIMB 8052 or derivatives thereof, including, but not limited to, Clostridium beijerinckii BA101, ATCC No. PTA-1550, by contacting the reaction medium directly with an adsorbent that selectively adsorbs the solvent; separating the adsorbent/solvent adsorbate from the reaction medium; and desorbing the solvent adsorbate from the adsorbent.

Abstract: A unique valve assembly for simulated bed moving chromatography employs a combination of pressure compatible sealable materials that permit minimal frictional interaction between moving parts, ensures alignment of parts, and provides a method for conducting SMB countercurrent chromatography on a small scale, in which purity and separation efficiency are enhanced. Machine designs are disclosed which embody the SMB concepts. Finally, a quick disconnect connector and adaptor is provided for mounting chromatographic columns in an SMB device. Demonstration of this system in a fructose-glucose isomer separation with purity-recovery trade-off for this device is also presented.

Abstract: The present invention provides devices and methods for micro-scale simulated moving bed chromatography (SMB) for continuous preparation of analytic quantities of highly pure fractions of target molecules. The present apparatus and method of the invention is adapted in a preferred embodiment to separations by affinity chromatography involving three discontinuous liquid flow loops. An alternative embodiment of affinity chromatography utilizes standard SMB operating under isocratic conditions.
