摘要：Cultivation structure in the form of a portion of fabric like material web, whereat least one of the two large surfaces of the cultivation structure, during the cultivationforms an immobilization surface for microorganisms distributed in a nutrient solution,above the respective surface, is claimed. The cultivation structure consists of at least onepredominantly hydrophobic material and its immobilization surface or surfaces exhibits apermanently hydrophilic structure as a result of temporary wetting at least once with awetting agent. Independent claims are also included for: (1) producing a cultivationstructure for cultivating phototrophic microorganisms, comprising producing animmobilization surface for microorganisms distributed in a nutrient solution for
cultivating the microorganisms, above the respective surface, on at least one of the largesurfaces of a portion of a fabric like material web, where a material web of at least onepredominantly hydrophobic material is used for preparing the cultivation structure and
(a) the provided surface or surfaces of the relevant material web is wetted with a solutioncomprising at least one surfactant in a concentration of 10-50 ppm, for the formation ofan immobilization surface, and (b) at least one portion corresponding to the providedgeometry of the cultivation structure is produced, where the two steps (a) and (b) can becarried out in reverse order; and (2) cultivation method for phototrophic microorganisms,comprising immobilizing the microorganisms on at least one vertically arranged
cultivation structure, where above at least one cultivation structure, an aqueous nutrientsolution with the microorganisms to be inoculated is applied, and the microorganismsafter the inoculation, immobilized on at least one cultivation structure, are cultivated withthe supply of natural or artificial light and gaseous nutrients, where the nutrient solutionapplied above at least one cultivation structure, comprises at least one surfactant, wherethe concentration of at least one surfactant during the first application of the nutrientsolution, which is carried out in a circle, amounts to 10-50 ppm.
