    Abstract: Provided herein is a method for capturing DNA molecules in solution. The method may comprise: extracting DNA from a sample that comprises endogenous DNA and environmental DNA to produce extracted DNA; ligating universal adaptors to the extracted DNA; hybridizing the extracted DNA, in solution, with affinity-tagged RNA probes generated by: in vitro transcribing a library of fragmented reference genomic DNA that has been ligated to an RNA promoter adaptor, in the presence of an affinity-tagged ribonucleotide; binding the product with a capture agent that is tethered to a substrate in the presence of RNA oligonucleotides that are complementary to the adaptors, thereby capturing the hybridized DNA molecules on the substrate; washing the substrate to remove any unbound DNA molecules; and releasing the captured DNA molecules. A kit for performing the method is also provided.

    Abstract: A scalable process and device for producing a bio molecule, in particular pharmaceutical grade plasmid DNA is described. The process includes the steps of alkaline lysis, neutralization and clarification and can be further extended. For separating the lysate and the precipitate an improved floatation method is disclosed. This method is based on attachment of CO2 bubbles on the precipitate floe. The CO2 is released from a carbonate salt during or after neutralization (acidification). The method of the invention is preferably carried out in an automated continuous mode applying devices for lysis and neutralization and a novel device for completely continuous clarification (separation of floes and clarified lysate).
