Immobilied blue-green algae in sheet form |
| abstract |
A composite structure having a thickness substantially less than its width such as a sheet is prepared which includes a substantially water-insoluble particulate or fibrous support having a surface energy of at least about 30 dynes per cm to which nitrogen-fixing filamentous blue-green algae heterocyst cells are attached. the support does not have a deleterious effect on the attached algae and is preferably cellulosic or a polyoletin such a polypropylene. The structure may contain a first and second layer and have a plurality of raised, three-dimensional shapes over at least a portion of at least one surface. Preparing the composite structure includes contacting the support with blue-green algae to permit the algae to attach to the support by means of heterocyst cells. The attach cells in a nitrogen deficient environment, fix nitrogen at a rate substantially greater than unattached cells, and have agricultural applications. |
