A coupling system for the transfer of a flat object from a confinement box towards a processing unit for processing the flat object. The coupling system includes a first shutter, at least one second opening, a second shutter, and a third shutter associated with the second opening on a side facing the processing unit, and devices for releasing the first, second and third shutter, after coupling the transfer opening of the confinement box with the transfer opening of the processing unit, in order to allow the transfer of the object between the confinement box and the processing unit.

Disclosed is a single-use bioreactor bag design providing substantially equivalent maximum shear rate at the impeller tip and average or bulk shear rate over a range of power per unit working volume and rpm needed for bioculture processing. The uniformity in shear profile of the bag design providing a unique advantage when used as a scale-down or scale-up platform. Also disclosed is a linearly scalable, single-use, bioreactor system for use in carrying out a scalable biomanufacturing process, the system comprising two single-use bioreactor bags of different volumes, wherein the ratio H/D of the height of the working volume H to the diameter D of the tank, or of the bag is equal to about 1.5, and the bulk shear in each of the bags is substantially constant. The disclosed small scale system models larger scale systems from both a shear/scalability/performance basis and also from a validation and regulatory basis. In summary, the 10 L bioreactor system disclosed provides for “linear scalability” by using the same or substantially simulating the same vessel geometry, gas sparging system, impeller shape and type, polymer composition of the flexible bag/components, process control system, and shear rates as larger 50-5000 L systems.

Provided are a method and a device for synthesizing proteins from DNA molecules captured in microchambers, whereby the distance between microchambers can be shortened, thereby allowing the density of arrays to be increased. Microchambers (32) are arranged at a high density. A DNA solution (34) which has been diluted so as to capture one DNA molecule on average is enclosed in the microchambers (32). Then, mRNA is synthesized using one DNA molecule on average as a template. Based on this mRNA, a protein (37) is extracellularly synthesized.

An evaporator is provided, comprising a heating core shell and a heating core assembly; the heating core assembly comprises a pipe bowl container, a cavity air passage structure, a heating element and a control circuit; the control circuit is configured to heat the heating element according to received trigger signals from different trigger paths, the heating element is configured to conduct heat energy to and evaporate a matter to be evaporated stored in the pipe bowl container, and evaporated gas is guided to outside of the heating core shell through the cavity air passage structure. A control method of the evaporator is also provided. The pipe bowl container is convenient for cleaning, and the control circuit receives signals from different trigger paths to heat the heating element, so as to make the heating working state of the control and operation of the heating element more concise and convenient.

The present invention relates to a cell for producing acyl glycinates wherein the cell is genetically modified to comprise

• • at least a first genetic mutation that increases the expression relative to the wild type cell of an amino acid-N-acyl-transferase,
  • at least a second genetic mutation that increases the expression relative to the wild type cell of an acyl-CoA synthetase, and
  • at least a third genetic mutation that decreases the expression relative to the wild type cell of at least one enzyme selected from the group consisting of an enzyme of the glycine cleavage system, glycine hydroxymethyltransferase (GlyA) and threonine aldolase (LtaE).

The present invention refers to a process for the purification of levulinic acid, an aqueous solution comprising levulinic acid and a process for the production of levulinic acid.

The present invention provides a cytokine-based culture method for ex vivo expansion of NK cells from postembryonic hematopoietic stem cells into a fully closed, large-scale, cell culture bioprocess. We optimized enrichment of CD34⁺ cells followed by efficient expansion in gas-permeable cell culture bags. Thereafter, expanded CD34⁺ cells could be reproducibly amplified and differentiated into CD56⁺CD3⁻ NK cell products with a mean expansion of more than 2,000 fold and a purity of >90%. Also provided are collections of cultured cells having specific properties.

An exemplary single bed reversing blower adsorption based air separation unit is configured to follow the O₂ load placed thereon by adjusting flow rates therethrough and power consumption. At least one and preferably multiple pressure sensors sense O₂ pressure within an O₂ storage region downstream of an adsorber vessel. These sensed pressures are utilized to generate control signals controlling flow rates at locations upstream of the compressor, such as at a reversible blower and an output compressor. Control loops for the blower and the compressor are independent of each other and have different time constants. Effective following of the O₂ load is thus achieved without driving the air separation unit into operational conditions outside of design and also maintaining optimal power consumption for the O₂ produced, such that efficiency is maintained over a large turndown ratio.

The present invention relates to a process of producing a monoterpene and/or derivatives thereof. The process comprises the steps of: a) providing a host microorganism genetically engineered to express a bacterial monoterpene synthase (mTS); and b) contacting geranyl pyrophosphate (GPP) with said bacterial mTS to produce said monoterpene and/or derivatives thereof. The present invention also relates to a microorganism for use in producing a monoterpene and/or derivatives thereof and a recombinant microorganism adapted to conduct the step of converting geranyl pyrophosphate (GPP) into a monoterpene and/or derivatives thereof by expression of a bacterial mTS. It was shown to produce 1,8 cineole using 1,8 cineole synthase and to produce linalool using linalool synthase, both from Streptomyces clavuligerus.
