ABSTRACT:
A composite is prepared which includes a substantially water-insoluble particulate or fibrous support having a surface energy of at least about 19 dynes per cm to which nitrogen-fixing filamentous heterocystous blue-green algae are attached. The support does not have a deleterious effect on the viability of the attached algae, and is preferably polypropylene or cellulosic. Preparing the composite includes contacting the support with blue-green algae to permit the algae to attach to the support by means of heterocyst cells. The attached cells in a nitrogen-deficient environment, fix nitrogen at a rate substantially greater than unattached cells, and have agricultural applications.
