Title: Virutas de madera con microorganismos, su preparación y su uso
Inventor: FERRER SOLER SERGIO
IPC: C12G1/073

Granted: 2018-04-16
Abstract: Virutas de madera con microorganismos, su preparación y su uso.#El método de la presente invención permite obtener cultivos de microorganismos inmovilizados en virutas o chips de roble recubiertos de almidón. Utiliza chips de roble sin deslignificar, de uso permitido en vinos. Los microorganismos quedan inmovilizados en los poros de las virutas o chips, prefiriéndose las especies de roble de alta porosidad y, especialmente, los chips sin tostar, que dan lugar a mejor viabilidad de los microorganismos, junto con la inmovilización por liofilización. Los chips obtenidos son especialmente útiles en la elaboración del vino, porque simultáneamente imparten características de la madera e intervienen en las fermentaciones. Los co-inmovilizados de levaduras y bacterias malolácticas permiten fermentación alcohólica y maloláctica simultáneas, acelerando la producción. Las levaduras de fermentación alcohólica inmovilizadas en estos chips pueden aplicarse en la segunda fermentación de espumosos, donde facilitan la eliminación de levaduras y aportan nuevas características organolépticas.

Granted: 1990-07-12
Abstract: An optical image is passed through a colour stripe filter having recurrent groups of different colour stripes to a photoelectical conversion target. The latter is scanned by an electron beam to generate a video signal comprising a carrier having a frequency inversely proportional to the intervals at which the recurrent groups of the strips are arranged. The carrier is modulated in phase with the stripes of each group and in amplitude with the intensity of the optical image. Prior to operation, the target is uniformly illuminated with light of a predetermined colour to generate the carrier, which is stored in a field memory. During operation, the memory is repeatedly addressed to generate a reference signal.
