The invention relates to a biochemical method for preparing scopolamine, and belongs to the technical field of bioengineering. The invention aims to realize efficient conversion from scopolamine to scopolamine and improve the yield and industrial applicability of a target product. The invention provides a biochemical method for preparing scopolamine. The biochemical method comprises the following steps: adding scopolamine 6 beta hydroxylase into a culture medium containing L-scopolamine; the amino acid sequence of the hyoscyamine 6 beta hydroxylase is shown as any one of SEQ ID NO.1-5. The invention further discloses a preparation method of the hyoscyamine 6 beta hydroxylase. And the biochemical engineering method for realizing efficient and high-selectivity synthesis of scopolamine is realized.

The present invention relates to an apparatus for use in a biotechnological process, the apparatus comprising a vessel and a separator. The present invention also relates to a method for controlling flow of cells and culture medium between a vessel and a separator.

The utility model relates to the technical field of biochemical engineering extraction, and discloses biochemical engineering extraction equipment which comprises a base, a plurality of rolling rods are connected to the upper surface of the base in an embedded and rolling mode from left to right, the upper surfaces of the rolling rods are jointly and movably connected with a C-shaped base, and an extraction tank is fixedly connected to the interior of the C-shaped base in a penetrating mode. A shaking mechanism is arranged on the upper surface of the base and located on the right side of the rightmost rolling rod, and a supporting block is mounted above the extraction tank. An adjusting mechanism for driving the supporting block to lift is arranged on the upper surface of the extraction tank; the first motor in the shaking mechanism drives the turntable to rotate to drive the extraction tank to shake, so that the mixing of the biochemical engineering extract and the extraction agent is accelerated, meanwhile, the second motor drives the stirring rod to rotate, the mixing of the biochemical engineering extract and the extraction agent is further accelerated, and the adjusting mechanism drives the stirring rod to leave the material. The stirring rod is prevented from influencing the standing effect of the materials, and the influence on subsequent layering is also avoided.

The system (1000, 1000') enables realising a method for transferring objects and / or materials (A) and a pharmaceutical, microbiological or biotechnological process comprising the method.

A flow cell for optical spectroscopy is provided with a housing having a cavity which forms a measuring chamber, inlet and outlet channels and an optical window which seals an opening of the measuring chamber. The optical window is connected to the housing by melting a glass connecting element. A recess is formed around the opening and a supporting surface for the optical window is formed around the opening, so that the optical window contacts the housing at the supporting surface. The use of such a flow cell in processes monitoring of biotechnological processes and methods is also disclosed.
