A method for the production of natural L-cysteine by fermentation in a production fermenter in which a microorganism strain is cultured in a fermentation medium, characterized in that the fraction of the compounds L-cysteine, L-cystine and thiazolidine in the fermentation medium is controlled in a targeted manner by an iron concentration of a maximum of 8 mg/l in the fermentation medium.
摘要:
The invention relates to an antenna core, an antenna comprising an antenna core, and to methods for producing an antenna core and an antenna. The antenna core used in each case consists of a continuous soft-magnetic strip having a plurality of layers which are stacked one on top of the other and each of which is formed by a section of the strip. The layers are connected to one another by curved sections of the strip at end regions of the antenna core.

A connecting arrangement (1) is provided for connecting a stiffening beam (2) to a bracket (3) in a motor vehicle. The stiffening beam (2) and the bracket (3) having mounting sections (4, 5) that can be plugged into one another. The mounting sections (4, 5) each have two slots (6, 7) situated opposite one another. The slots (6, 7) at least partially overlap in pairs and are offset from one another by a predetermined angle (α) in the mounted position of the mounting sections (4, 5) to facilitate the insertion of a fastening element (12) into the slot pairs (6, 7). The connecting arrangement (1) simplifies the mounting of the fastening element (12) and enables an even retroactive correction or alignment of the connecting arrangement (1) in the plugging-together direction (13) of the mounting sections (4,5).

For the effective absorption of a side impact in a motor vehicle, a transversely extending component is provided in the vehicle that comprises a bearing element and profile parts situated on the ends thereof.
摘要:
A level sensor apparatus is disclosed for detecting contact of a pipetting needle with a liquid contained in a vessel. The apparatus includes a sensor head made up of a pipetting needle, a needle holder, and an electromechanical transducer. The sensor head also has an associated mechanical resonance frequency. An electrical signal generator is used to generate a driving signal which when applied to the electromechanical transducer causes vibration of the pipetting needle at the resonance frequency. A measurement device is used to measure a parameter of a vibration signal indicative of the mechanical vibration of the pipetting needle when it is driven by the driving signal. An electronic circuit and associated computer software is provided to evaluate variation of the vibration signal with time and thus detect contact of the pipetting needle with a liquid contained in the vessel.
