Abstract:
Offenbart wird ein Verfahren zum Erzeugen von Biogas durch Vergärung von pumpfähigen organischen Ausgangsmaterialien, insbesondere von Güllen und Jauchen aus der Tierhaltung, wobei - ein Zustrom des organischen Ausgangsmaterials aufgeteilt wird in einen Dickstoffanteil mit gegenüber dem Ausgangsmaterial höherem Feststoffanteil und einen flüssigkeitsdominierten Dünnstoffanteil mit gegenüber dem Ausgangsmaterial geringerem Feststoffanteil, - der Dünnstoffanteil einem Dünnstofffermenter (23), in dem Mikroorganismen auf in dem Füllvolumen des Dünnstofffermenters (23) in der Schwebe gehaltenen Aufwuchskörpern (27) aufgewachsen sind, zugeführt und dort fermentiert wird, - in dem Dünnstofffermenter (23) entstandenes Biogas aufgefangen und für eine weitere Verwendung abgeführt wird, - in dem Dünnstofffermenter (23) entstehende Gärreste abgeführt werden. Dieses Verfahren erlaubt den Betrieb von kompakten und zu günstigen Investitionskosten herzurichtenden Anlagen zur Biogasgewinnung. Eine hier ebenfalls offenbarte Vorrichtung zum Erzeugen von Biogas nach dem Verfahren ist insbesondere modular aufgebaut mit straßentransportfähigen Modulen.
Abstract:
An apparatus for collecting or culturing cells or cell colonies includes: a common substrate formed from a flexible resilient polymeric material and having a plurality of wells formed therein; and a plurality of rigid cell carriers releasably connected to said common substrate, with said carriers arranged in the form of an array, and with each of the carriers resiliently received in one of the wells. A method of collecting or culturing cells or cell colonies with such an apparatus is carried out by depositing a liquid media carrying cells on the apparatus so that said cells settle on or adhere to said the carriers; and then (c) releasing at least one selected carrier having said cells thereon by gradual application of release energy to each carrier from the cavity in which it is received (e.g., by pushing with a probe).
Abstract:
The present invention relates to a hybrid cell culturing system, a process for culturing cells using said hybrid cell culturing system, a cell culture device comprising said hybrid cell culturing system and use of at least one second cell culturing support designed to be arranged to at least one arrangement position of a first cell culturing support for culturing cells.
Abstract:
Processes are disclosed for bioconversion processes in which a ME biocatalyst is surrounded by water-insoluble liquid during the bioconversion to facilitate one or more of mass transfer of substrate to and bioproduct from the biocatalyst and the separation and recovery of bioproduct from the water-insoluble liquid. The ME biocatalyst irreversibly retains microorganisms for the bioconversion and has, in its interior, an aqueous environment.
Abstract:
This culture device (10) comprises: a culture container (10) which houses cells, magnetic particles and a culture medium; a temperature adjustment unit (5) for adjusting the temperature of the culture container (10); a magnet (7a) which is provided to the outside of the culture container (10); a magnetic force adjustment unit (7b) for adjusting the magnetic force of the magnet (7a); and a control unit for controlling the operation of the magnetic force adjustment unit (7b). The magnetic force adjustment unit (7b) adjusts the magnetic force of the magnet (7b), thereby holding magnetic particles and cells in a predetermined region within the culture container (10), or dispersing the magnetic particles and cells within the culture container.
Abstract:
A photobioreactor for CO2 biosequestration according to the invention has a biomass of algae or cyanobacteria immobilised in capsules (3) which have an outer envelope (4). The capsules of the biomass of algae or cyanobacteria (3) are supplied with light from a light source (6) by a separate, single light tube (5). In the photobioreactor, the capsules (3) are surrounded by a gaseous atmosphere and are wetted with a culture medium and periodically flushed. The photobioreactor is polyhedral or circular in its cross section.
