Abstract: Procedimiento para la producción de ácido D-pantoténico y/o sus sales, caracterizado porque e) se utiliza al menos un microorganismo que produce ácido D-pantoténico, cuya biosíntesis de ácido pantoténico (pan) y/o de isoleucina/valina (ilv) está desregulada y que forma al menos 2 g/l de sales del ácido pantoténico mediante la fermentación en un medio de cultivo, añadiéndose al medio de cultivo 0 - 20 g/l de Beta-alanina libre y/o sal de Beta-alanina, f) se conduce la solución de fermentación que contiene D-pantotenato mediante la aplicación de un campo eléctrico a través de una o varias membranas selectivas de iones, eliminándose los iones de bajo peso molecular de la solución que contiene D-pantotenato, g) se ajusta el ácido D-pantoténico libre contenido en la solución mediante la adición de una base de calcio y/o de magnesio hasta un valor de pH de 3-10, obteniéndose una solución, que contiene pantotenato de calcio y/o de magnesio y h) se somete la solución que contiene pantotenato de calcio y/o de magnesio a un secado y/o formulación.

Abstract: The present invention relates to a process for the deionization of a cooling medium in a fuel cell (11) circulating in a cooling circuit (20), in which the cooling medium is subjected to at least intermittent, but preferably continuous, electrochemical deionization. To this end, at least one electrode deionization cell (23) , through which a diluate stream (27) serving as cooling medium and a concentrate stream (28) flow, is arranged in the cooling circuit. The concentrate stream (28) may be part of a secondary cooling circuit.

Abstract: Microreactors enabling mixing together of two or more gaseous and /or liquid phases comprise modular blocks which have feed channels (4, 6) for each component, connecting with multiple mixing chambers (3), and discharge channels (5, 7) for products. Different flow paths and numbers of mixing operations can be configured. The blocks may be formed from metal, glass or plastics materials.

The cathode is made from a material of the formula: (Sr1-xCax)1-yAyMn1-zBzO3-d (where A = Ba, Pb, Na, K, Y or lanthanide; B = Mg, Al, Ga, In, Sn or group IVb, Vb or VIb element; x = 0.2-0.8; y = 0-0.4; z = 0 to 1; and d = a value which takes into account the electro-neutrality principle). Preferred Features: The electrolyte is made from tetragonal zirconia polycrystals, scandium doped cubic stabilized zirconium oxide, lanthanum-strontium-gallium-magnesium oxide having a perovskite structure, gadolinium oxide doped cerium oxide, BiCuVOx or BiErOx. The anode is made from metallic or oxide ion conducting materials or a mixed-conducting material having catalytically active components.
